+
+New Features
+============
+
+    Configuration:
+    -------------
+    - Add toolchain and cross-compile support
+
+      Added info on using a toolchain file to INSTALL_CMAKE.txt. A
+      toolchain file is also used in cross-compiling, which requires
+      CMAKE_CROSSCOMPILING_EMULATOR to be set. To help with cross-compiling
+      the fortran configure process, the HDF5UseFortran.cmake file macros
+      were improved. Fixed a Fortran configure file issue that incorrectly
+      used #cmakedefine instead of #define.
+
+      (ADB - 2018/10/04, HDFFV-10594)
+
+    - Add warning flags for Intel compilers
+
+      Identified Intel compiler specific warnings flags that should be used
+      instead of GNU flags.
+
+      (ADB - 2018/10/04, TRILABS-21)
+
+    - Add default rpath to targets
+
+      Default rpaths should be set in shared executables and
+      libraries to allow the use of loading dependent libraries
+      without requiring LD_LIBRARY_PATH to be set. The default
+      path should be relative using @rpath on osx and $ORIGIN
+      on linux. Windows is not affected.
+
+      (ADB - 2018/09/26, HDFFV-10594)
+
+    Library:
+    --------
+    - Allow pre-generated H5Tinit.c and H5make_libsettings.c to be used.
+
+      Rather than always running H5detect and generating H5Tinit.c and
+      H5make_libsettings.c, supply a location for those files.
+
+      (ADB - 2018/09/18, HDFFV-10332)
+
+
+Bug Fixes since HDF5-1.10.3 release
+==================================
+
+    Library
+    -------
+    - Allow H5detect and H5make_libsettings to take a file as an argument.
+
+      Rather than only writing to stdout, add a command argument to name
+      the file that H5detect and H5make_libsettings will use for output.
+      Without an argument, stdout is still used, so backwards compatibility
+      is maintained.
+
+      (ADB - 2018/09/05, HDFFV-9059)
+
+    - A bug was discovered in the parallel library where an application
+      would hang if a collective read/write of a chunked dataset occurred
+      when collective metadata reads were enabled and some of the ranks
+      had no selection in the dataset's dataspace. The ranks which had no
+      selection in the dataset's dataspace called H5D__chunk_addrmap() to
+      retrieve the lowest chunk address in the dataset. This is because we
+      require reads/writes to be performed in strictly non-decreasing order
+      of chunk address in the file.
+
+      When the chunk index used was a version 1 or 2 B-tree, these
+      non-participating ranks would issue a collective MPI_Bcast() call
+      that the participating ranks would not issue, causing the hang. Since
+      the non-participating ranks are not actually reading/writing anything,
+      the H5D__chunk_addrmap() call can be safely removed and the address used
+      for the read/write can be set to an arbitrary number (0 was chosen).
+
+      (JTH - 2018/08/25, HDFFV-10501)
+
+    Java Library:
+    ----------------
+    - JNI native library dependencies
+    
+      The build for the hdf5_java native library used the wrong
+      hdf5 target library for CMake builds. Correcting the hdf5_java
+      library to build with the shared hdf5 library required testing
+      paths to change also.
+
+      (ADB - 2018/08/31, HDFFV-10568)
+
+    - Java iterator callbacks
+
+      Change global callback object to a small stack structure in order
+      to fix a runtime crash. This crash was discovered when iterating
+      through a file with nested group members. The global variable
+      visit_callback is overwritten when recursion starts. When recursion
+      completes, visit_callback will be pointing to the wrong callback method.
+
+      (ADB - 2018/08/15, HDFFV-10536)
+
+    - Java HDFLibraryException class
+
+      Change parent class from Exception to RuntimeException.
+
+      (ADB - 2018/07/30, HDFFV-10534)
+
+    - JNI Read and Write
+
+      Refactored variable-length functions, H5DreadVL and H5AreadVL,
+      to correct dataset and attribute reads. New write functions,
+      H5DwriteVL and H5AwriteVL, are under construction.
+
+      (ADB - 2018/06/02, HDFFV-10519)

+Known Problems
+==============
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Three tests fail with OpenMPI 3.0.0/GCC-7.2.0-2.29:
+        testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio)
+        t_shapesame (sscontig2)
+        t_pflush1/fails on exit
+    The first two tests fail attempting collective writes.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.
+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

+New Features
+============
+
+    Library
+    -------
+    - Moved the H5DOread/write_chunk() API calls to H5Dread/write_chunk()
+
+      The functionality of the direct chunk I/O calls in the high-level
+      library has been moved to the H5D package in the main library. This
+      will allow using those functions without building the high-level
+      library. The parameters and functionality of the H5D calls are
+      identical to the H5DO calls.
+
+      The original H5DO high-level API calls have been retained, though
+      they are now just wrappers for the H5D calls. They are marked as
+      deprecated and are only available when the library is built with
+      deprecated functions. New code should use the H5D calls for this
+      reason.
+
+      As a part of this work, the following symbols from H5Dpublic.h are no
+      longer used:
+
+        H5D_XFER_DIRECT_CHUNK_WRITE_FLAG_NAME
+        H5D_XFER_DIRECT_CHUNK_WRITE_FILTERS_NAME
+        H5D_XFER_DIRECT_CHUNK_WRITE_OFFSET_NAME
+        H5D_XFER_DIRECT_CHUNK_WRITE_DATASIZE_NAME
+        H5D_XFER_DIRECT_CHUNK_READ_FLAG_NAME
+        H5D_XFER_DIRECT_CHUNK_READ_OFFSET_NAME
+        H5D_XFER_DIRECT_CHUNK_READ_FILTERS_NAME
+
+      And properties with these names are no longer stored in the dataset
+      transfer property lists. The symbols are still defined in H5Dpublic.h,
+      but only when the library is built with deprecated symbols.
+
+      (DER - 2018/05/04)
+
+    Configuration:
+    -------------
+    - Add missing USE_110_API_DEFAULT option.
+
+      Option USE_110_API_DEFAULT sets the default version of
+      versioned APIs. The bin/makevers perl script did not set
+      the maxidx variable correctly when the 1.10 branch was
+      created. This caused the versioning process to always use
+      the latest version of any API.
+
+      (ADB - 2018/08/17, HDFFV-10552)
+
+    - Added configuration checks for the following MPI functions:
+
+      MPI_Mprobe - Used for the Parallel Compression feature
+      MPI_Imrecv - Used for the Parallel Compression feature
+
+      MPI_Get_elements_x - Used for the "big Parallel I/O" feature
+      MPI_Type_size_x - Used for the "big Parallel I/O" feature
+
+      (JTH - 2018/08/02, HDFFV-10512)
+
+    - Added section to the libhdf5.settings file to indicate
+      the status of the Parallel Compression and "big Parallel I/O"
+      features.
+
+      (JTH - 2018/08/02, HDFFV-10512)
+
+    - Add option to execute swmr shell scripts from CMake.
+
+      Option TEST_SHELL_SCRIPTS redirects processing into a
+      separate ShellTests.cmake file for UNIX types. The tests
+      execute the shell scripts if a SH program is found.
+
+      (ADB - 2018/07/16)
+
+
+    C++ Library:
+    ------------
+    - New wrappers
+
+      Added the following items:
+
+      + Class DSetAccPropList for the dataset access property list.
+
+      + Wrapper for H5Dget_access_plist to class DataSet
+        // Gets the access property list of this dataset.
+        DSetAccPropList getAccessPlist() const;
+
+      + Wrappers for H5Pset_chunk_cache and H5Pget_chunk_cache to class DSetAccPropList
+        // Sets the raw data chunk cache parameters.
+        void setChunkCache(size_t rdcc_nslots, size_t rdcc_nbytes, double rdcc_w0)
+
+        // Retrieves the raw data chunk cache parameters.
+        void getChunkCache(size_t &rdcc_nslots, size_t &rdcc_nbytes, double &rdcc_w0)
+
+      + New operator!= to class DataType (HDFFV-10472)
+        // Determines whether two datatypes are not the same.
+        bool operator!=(const DataType& compared_type)
+
+      + Wrappers for H5Oget_info2, H5Oget_info_by_name2, and H5Oget_info_by_idx2
+        (HDFFV-10458)
+
+        // Retrieves information about an HDF5 object.
+        void getObjinfo(H5O_info_t& objinfo, unsigned fields = H5O_INFO_BASIC) const;
+
+        // Retrieves information about an HDF5 object, given its name.
+        void getObjinfo(const char* name, H5O_info_t& objinfo,
+                unsigned fields = H5O_INFO_BASIC,
+                const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;
+        void getObjinfo(const H5std_string& name, H5O_info_t& objinfo,
+                unsigned fields = H5O_INFO_BASIC,
+                const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;
+
+        // Retrieves information about an HDF5 object, given its index.
+        void getObjinfo(const char* grp_name, H5_index_t idx_type,
+                H5_iter_order_t order, hsize_t idx, H5O_info_t& objinfo,
+                unsigned fields = H5O_INFO_BASIC,
+                const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;
+        void getObjinfo(const H5std_string& grp_name, H5_index_t idx_type,
+                H5_iter_order_t order, hsize_t idx, H5O_info_t& objinfo,
+                unsigned fields = H5O_INFO_BASIC,
+                const LinkAccPropList& lapl = LinkAccPropList::DEFAULT) const;

+
+
+    Java Library:
+    ----------------
+    - Java HDFLibraryException class
+
+      Change parent class from Exception to RuntimeException.
+
+      (ADB - 2018/07/30, HDFFV-10534)
+
+    - JNI Read and Write
+
+      Refactored variable-length functions, H5DreadVL and H5AreadVL,
+      to correct dataset and attribute reads. New write functions,
+      H5DwriteVL and H5AwriteVL, are under construction.
+
+      (ADB - 2018/06/02, HDFFV-10519)
+
+
+Bug Fixes since HDF5-1.10.2 release
+==================================
+
+    Library
+    -------
+    - Performance issue with H5Oget_info
+
+      H5Oget_info family of routines retrieves information for an object such
+      as object type, access time, number of attributes, and storage space etc.
+      Retrieving all such information regardless is an overkill and causes
+      performance issue when doing so for many objects.
+
+      Add an additional parameter "fields" to the the H5Oget_info family of routines
+      indicating the type of information to be retrieved.  The same is done to
+      the H5Ovisit family of routines which recursively visits an object
+      returning object information in a callback function.  Both sets of routines
+      are versioned and the corresponding compatibility macros are added.
+
+      The version 2 names of the two sets of routines are:
+        (1) H5Oget_info2, H5Oget_info_by_idx2, H5Oget_info_by_name2
+        (2) H5Ovisit2, H5Ovisit_by_name2
+
+      (VC - 2018/08/15, HDFFV-10180)
+
+    - Test failure due to metadata size in test/vds.c
+
+      The size of metadata from test_api_get_ex_dcpl() in test/vds.c is not as expected
+      because the latest format should be used when encoding the layout for VDS.
+
+      Set the latest format in a temporary fapl and pass the setting to the routines that
+      encode the dataset selection for VDS.
+
+      (VC - 2018/08/14 HDFFV-10469)
+
+    - Java HDF5LibraryException class
+
+      The error minor and major values would be lost after the
+      constructor executed.
+
+      Created two local class variables to hold the values obtained during
+      execution of the constructor. Refactored the class functions to retrieve
+      the class values rather then calling the native functions.
+      The native functions were renamed and called only during execution
+      of the constructor.
+      Added error checking to calling class constructors in JNI classes.
+
+      (ADB - 2018/08/06, HDFFV-10544)
+
+    - Added checks of the defined MPI_VERSION to guard against usage of
+      MPI-3 functions in the Parallel Compression and "big Parallel I/O"
+      features when HDF5 is built with MPI-2. Previously, the configure
+      step would pass but the build itself would fail when it could not
+      locate the MPI-3 functions used.
+
+      As a result of these new checks, HDF5 can again be built with MPI-2,
+      but the Parallel Compression feature will be disabled as it relies
+      on the MPI-3 functions used.
+
+      (JTH - 2018/08/02, HDFFV-10512)
+
+    - User's patches: CVEs
+
+      The following patches have been applied:
+
+      CVE-2018-11202 - NULL pointer dereference was discovered in

+
+      CVE-2018-11206 - An out of bound read was discovered in
+                       H5O_fill_new_decode and H5O_fill_old_decode in H5Ofill.c
+                       (HDFFV-10480)

+
+      CVE-2018-11207 - A division by zero was discovered in

+        https://cve.mitre.org/cgi-bin/cvename.cgi?name=3DCVE-2018-11207
+
+      (BMR - 2018/7/22, PR#s: 1134 and 1139,
+       HDFFV-10476, HDFFV-10477, HDFFV-10478, HDFFV-10480, HDFFV-10481)
+
+    - H5Adelete
+
+      H5Adelete failed when deleting the last "large" attribute that
+      is stored densely via fractal heap/v2 b-tree.
+
+      After removing the attribute, update the ainfo message.  If the
+      number of attributes goes to zero, remove the message.
+
+      (VC - 2018/07/20, HDFFV-9277)
+
+    - A bug was discovered in the parallel library which caused partial
+      parallel reads of filtered datasets to return incorrect data. The
+      library used the incorrect dataspace for each chunk read, causing
+      the selection used in each chunk to be wrong.
+
+      The bug was not caught during testing because all of the current
+      tests which do parallel reads of filtered data read all of the data
+      using an H5S_ALL selection. Several tests were added which exercise
+      partial parallel reads.
+
+      (JTH - 2018/07/16, HDFFV-10467)
+
+    - A bug was discovered in the parallel library which caused parallel
+      writes of filtered datasets to trigger an assertion failure in the
+      file free space manager.
+
+      This occurred when the filter used caused chunks to repeatedly shrink
+      and grow over the course of several dataset writes. The previous chunk
+      information, such as the size of the chunk and the offset in the file,
+      was being cached and not updated after each write, causing the next write
+      to the chunk to retrieve the incorrect cached information and run into
+      issues when reallocating space in the file for the chunk.
+
+      (JTH - 2018/07/16, HDFFV-10509)
+
+    - A bug was discovered in the parallel library which caused the
+      H5D__mpio_array_gatherv() function to allocate too much memory.
+
+      When the function is called with the 'allgather' parameter set
+      to a non-true value, the function will receive data from all MPI
+      ranks and gather it to the single rank specied by the 'root'
+      parameter. However, the bug in the function caused memory for
+      the received data to be allocated on all MPI ranks, not just the
+      singular rank specified as the receiver. In some circumstances,
+      this would cause an application to fail due to the large amounts
+      of memory being allocated.
+
+      (JTH - 2018/07/16, HDFFV-10467)
+
+    - Error checks in h5stat and when decoding messages
+
+      h5stat exited with seg fault/core dumped when
+      errors are encountered in the internal library.
+
+      Add error checks and --enable-error-stack option to h5stat.
+      Add range checks when decoding messages: old fill value, old
+      layout and refcount.
+
+      (VC - 2018/07/11, HDFFV-10333)
+
+    - If an HDF5 file contains a malformed compound datatype with a
+      suitably large offset, the type conversion code can run off
+      the end of the type conversion buffer, causing a segmentation
+      fault.
+
+      This issue was reported to The HDF Group as issue #CVE-2017-17507.
+
+      NOTE: The HDF5 C library cannot produce such a file. This condition
+            should only occur in a corrupt (or deliberately altered) file
+            or a file created by third-party software.
+
+      THE HDF GROUP WILL NOT FIX THIS BUG AT THIS TIME
+
+      Fixing this problem would involve updating the publicly visible
+      H5T_conv_t function pointer typedef and versioning the API calls
+      which use it. We normally only modify the public API during
+      major releases, so this bug will not be fixed at this time.
+
+      (DER - 2018/02/26, HDFFV-10356)
+
+
+    Configuration
+    -------------
+    - Applied patches to address Cywin build issues
+
+      There were three issues for Cygwin builds:
+      - Shared libs were not built.
+      - The -std=c99 flag caused a SIG_SETMASK undeclared error.
+      - Undefined errors when buildbing test shared libraries.
+
+      Patches to address these issues were received and incorporated in this version.
+
+      (LRK - 2018/07/18, HDFFV-10475)
+
+    - The --enable-debug/production configure flags are listed as 'deprecated'
+      when they should really be listed as 'removed'.
+
+      In the autotools overhaul several years ago, we removed these flags and
+      implemented a new --enable-build-mode= flag. This was done because we
+      changed the semantics of the modes and didn't want users to silently
+      be exposed to them. The newer system is also more flexible and us to
+      add other modes (like 'clean').
+
+      The --enable-debug/production flags are now listed as removed.
+
+      (DER - 2018/05/31, HDFFV-10505)
+
+    - Moved the location of gcc attribute.
+
+      The gcc attribute(no_sanitize), named as the macro HDF_NO_UBSAN,
+      was located after the function name. Builds with GCC 7 did not
+      indicate any problem, but GCC 8 issued errors. Moved the
+      attribute before the function name, as required.
+
+      (ADB - 2018/05/22, HDFFV-10473)
+
+    - Reworked java test suite into individual JUnit tests.
+
+      Testing the whole suite of java unit tests in a single JUnit run
+      made it difficult to determine actual failures when tests would fail.
+      Running each file set of tests individually, allows individual failures
+      to be diagnosed easier. A side benefit is that tests for optional components
+      of the library can be disabled if not configured.
+
+      (ADB - 2018/05/16, HDFFV-9739)
+
+    - Converted CMake global commands ADD_DEFINITIONS and INCLUDE_DIRECTORIES
+      to use target_* type commands. This change modernizes the CMake usage
+      in the HDF5 library.
+
+      In addition, there is the intention to convert to generator expressions,
+      where possible. The exception is Fortran FLAGS on Windows Visual Studio.
+      The HDF macros TARGET_C_PROPERTIES and TARGET_FORTRAN_PROPERTIES have
+      been removed with this change in usage.
+
+      The additional language (C++ and Fortran) checks have also been localized

+Known Problems
+==============
+
+    At present, metadata cache images may not be generated by parallel
+    applications.  Parallel applications can read files with metadata cache
+    images, but since this is a collective operation, a deadlock is possible
+    if one or more processes do not participate.
+
+    Three tests fail with OpenMPI 3.0.0/GCC-7.2.0-2.29:
+        testphdf5 (ecdsetw, selnone, cchunk1, cchunk3, cchunk4, and actualio)
+        t_shapesame (sscontig2)
+        t_pflush1/fails on exit
+    The first two tests fail attempting collective writes.
+
+    Known problems in previous releases can be found in the HISTORY*.txt files
+    in the HDF5 source. Please report any new problems found to
+    help@hdfgroup.org.
+
+
+CMake vs. Autotools installations
+=================================
+While both build systems produce similar results, there are differences.
+Each system produces the same set of folders on linux (only CMake works
+on standard Windows); bin, include, lib and share. Autotools places the
+COPYING and RELEASE.txt file in the root folder, CMake places them in
+the share folder.
+
+The bin folder contains the tools and the build scripts. Additionally, CMake
+creates dynamic versions of the tools with the suffix "-shared". Autotools
+installs one set of tools depending on the "--enable-shared" configuration
+option.
+  build scripts
+  -------------
+  Autotools: h5c++, h5cc, h5fc
+  CMake: h5c++, h5cc, h5hlc++, h5hlcc
+
+The include folder holds the header files and the fortran mod files. CMake
+places the fortran mod files into separate shared and static subfolders,
+while Autotools places one set of mod files into the include folder. Because
+CMake produces a tools library, the header files for tools will appear in
+the include folder.
+
+The lib folder contains the library files, and CMake adds the pkgconfig
+subfolder with the hdf5*.pc files used by the bin/build scripts created by
+the CMake build. CMake separates the C interface code from the fortran code by
+creating C-stub libraries for each Fortran library. In addition, only CMake
+installs the tools library. The names of the szip libraries are different
+between the build systems.
+
+The share folder will have the most differences because CMake builds include
+a number of CMake specific files for support of CMake's find_package and support
+for the HDF5 Examples CMake project.

-HDF5 version 1.11.4 currently under development
-
-HDF5 source tar files with the HPC prefix are intended for use on clusters where 
-configuration and build steps will be done on a login node and executable and
-lib files that are built will be run on compute nodes.  
-
-Note these differences from the regular CMake tar and zip files:
-  - Test programs produced by this tar file will be run using batch scripts. 
-  - Serial and parallel HDF5options.cmake files, using parallel options by default.
-
-Note also that options are now available in HDF5 source to facilitate use of 
-toolchain files for using cross compilers available on login nodes to compile
-HDF5 for compute nodes.

-Instructions to configure build and test HDF5 using CMake:
-
-1. The cmake version must be 3.10 or later (cmake --version).
-2. Load or switch modules and set CC, FC, CXX for compilers desired.
-3. run build-unix.sh to configure, build, test and package HDF5 with CMake.

-
-To cross compile with this HPC-CMake tar.gz HDF5 source file:
-On Cray XC40  haswell login node for knl compute nodes using CMake and Cray modules:
-        1.  Uncomment line in HDF5options.txt to use a toolchain file - line 106 for
-            config/toolchain/crayle.cmake.
-        2.  Uncomment lines 110, 111, and 115 - 122 of HDF5options.cmake.
-            Line 110 allows configuring to complete on the haswell node.
-            Line 111 switches the compiler to build files for knl nodes.
-            Lines 115 - 122 set up test files to use sbatch to run build tests
-            in batch jobs on a knl compute node with 6 processes.
-        3.  Compiler module may be the default PrgEnv-intel/6.0.4 to use 
-            intel/18.0.2 or other intel, PrgEnv-cray/6.0.4 to use cce/8.7.4,
-            or PrgEnv-gnu/6.0.4 for GCC compilers.  PrgEnv-pgi/6.0.4 is also 
-            available but has not been tested with this tar file.
-        4.  These CMake options are set in config/toolchain/crayle.cmake:
-                set(CMAKE_SYSTEM_NAME Linux)
-                set(CMAKE_COMPILER_VENDOR "CrayLinuxEnvironment")
-                set(CMAKE_C_COMPILER cc)
-                set(CMAKE_CXX_COMPILER c++)
-                set(CMAKE_Fortran_COMPILER ftn)
-                set(CMAKE_CROSSCOMPILING_EMULATOR "")
-
-        5.  Settings for two other cross-compiling options are also in the 
-            config/toolchain files which do not seem to be necessary with the 
-            Cray PrgEnv-* modules
-            a.  HDF5_USE_PREGEN.  This option, along with the HDF5_USE_PREGEN_DIR
-                CMake variable would allow the use of an appropriate H5Tinit.c 
-                file with type information generated on a compute node to be used
-                when cross compiling for those compute nodes.  The use of the 
-                variables in lines 110 and 111 of HDF5options.cmake file seem to
-                preclude needing this option with the available Cray modules and
-                CMake options.
-            b.  HDF5_BATCH_H5DETECT and associated CMake variables.  This option
-                when properly configured will run H5detect in a batch job on a
-                compute node at the beginning of the CMake build process.  It 
-                was also found to be unnecessary with the available Cray modules
-                and CMake options.

+************************************************************************
+
+========================================================================
+I. Prerequisites
+========================================================================
+    1. Create a working directory that is accessible from the compute nodes for 
+       running tests; the working directory should be in a scratch space or a
+       parallel file system space since testing will use this space.  Building
+       from HDF5 source in a 'home' directory typically results in test 
+       failures and should be avoided.
+	  
+    2. Load modules for desired compilers, module for cmake version 3.10 or greater, 
+       and set any needed environment variables for compilers (i.e., CC, FC, CXX).
+       Unload any problematic modules (i.e., craype-hugepages2M).
+
+========================================================================
+II. Obtain HDF5 source
+========================================================================
+Obtain HDF5 source code from the HDF5 repository using a git command or 
+from a release tar file in a working directory:
+
+    git clone https://git@bitbucket.hdfgroup.org/scm/hdffv/hdf5.git 
+        [-b branch] [source directory]
+
+If no branch is specified, then the 'develop' version will be checked out.
+If no source directory is specified, then the source will be located in the 
+'hdf5' directory. The Cmake scripts expect the source to be in a directory 
+named hdf5-<version string>, where 'version string' uses the format '1.xx.xx'.
+For example, for the current 'develop' version, the "hdf5" directory should 
+be renamed "hdf5-1.11.4", or for the first hdf5_1_10_5 pre-release version, 
+it should be renamed "hdf5-1.10.5-pre1".
+
+If the version number is not known a priori, the version string 
+can be obtained by running bin/h5vers in the top level directory of the source clone, and
+the source directory renamed 'hdf5-<version string>'.
+
+Release or snapshot tar files may also be extracted and used.
+
+========================================================================
+III. Using ctest command to build and test
+========================================================================
+
+The ctest command [1]:
+
+  ctest -S HDF5config.cmake,BUILD_GENERATOR=Unix -C Release -V -O hdf5.log
+
+will configure, build, test and package HDF5 from the downloaded source 
+after the setup steps outlined below are followed.
+
+CMake option variables are available to allow running test programs in batch 
+scripts on compute nodes and to cross-compile for compute node hardware using 
+a cross-compiling emulator.  The setup steps will make default settings for
+parallel or serial only builds available to the CMake command.  
+
+    1. For the current 'develop' version the "hdf5" directory should be renamed 
+       "hdf5-1.11.4".
+
+    2. Three cmake script files need to be copied to the working directory, or
+       have symbolic links to them, created in the working directory:
+   
+       hdf5-1.11.4/config/cmake/scripts/HDF5config.cmake
+       hdf5-1.11.4/config/cmake/scripts/CTestScript.cmake
+       hdf5-1.11.4/config/cmake/scripts/HDF5options.cmake 
+
+       should be copied to the working directory.
+
+    3. The resulting contents of the working directory are then:
+
+       CTestScript.cmake
+       HDF5config.cmake
+       HDF5options.cmake
+       hdf5-1.11.4
+
+       Additionally, when the ctest command runs [1], it will add a build directory 
+       in the working directory.
+
+    4. The following options (among others) can be added to the ctest
+       command [1], following '-S HDF5config.cmake,' and separated by ',':
+
+       HPC=sbatch   (or 'bsub' or 'raybsub') indicates which type of batch
+                     files to use for running tests.  If omitted, test 
+                     will run on the local machine or login node.
+
+       KNL=true      to cross-compile for KNL compute nodes on CrayXC40
+                     (see section IV)
+
+       MPI=true      enables parallel, disables c++, java, and threadsafe
+
+       LOCAL_BATCH_SCRIPT_ARGS="--account=<account#>"  to supply user account
+                                                       information for batch jobs
+
+       The HPC options will add BUILD_GENERATOR=Unix for the three HPC options.
+       An example ctest command for a parallel build on a system using sbatch is
+   
+         ctest -S HDF5config.cmake,HPC=sbatch,MPI=true -C Release -V -O hdf5.log
+
+       Adding the option 'KNL=true' to the above list will compile for KNL nodes, 
+       for example, on 'mutrino' and other CrayXC40 machines.
+
+       Changing -V to -VV will produce more logging information in HDF5.log. 
+
+    More detailed CMake information can be found in the HDF5 source in 
+    release_docs/INSTALL_CMake.txt.
+
+========================================================================
+IV. Cross-compiling
+========================================================================
+For cross-compiling on Cray, set environment variables CC=cc, FC=ftn 
+and CXX=CC (for c++) after all compiler modules are loaded since switching
+compiler modules may unset or reset these variables.
+
+CMake provides options for cross-compiling.  To cross-compile for KNL hardware 
+on mutrino and other CrayXC40 machines, add HPC=sbatch,KNL=true to the 
+ctest command line.  This will set the following options from the 
+config/cmake/scripts/HPC/sbatch-HDF5options.cmake file:
+
+    set (COMPILENODE_HWCOMPILE_MODULE "craype-haswell")
+    set (COMPUTENODE_HWCOMPILE_MODULE "craype-mic-knl")
+    set (LOCAL_BATCH_SCRIPT_NAME "knl_ctestS.sl")
+    set (LOCAL_BATCH_SCRIPT_PARALLEL_NAME "knl_ctestP.sl")
+    set (ADD_BUILD_OPTIONS "${ADD_BUILD_OPTIONS} -DCMAKE_TOOLCHAIN_FILE:STRING=config/toolchain/crayle.cmake")
+
+On the Cray XC40 the craype-haswell module is needed for configuring, and the 
+craype-mic-knl module is needed for building to run on the KNL nodes. CMake
+with the above options will swap modules after configuring is complete, 
+but before compiling programs for KNL.
+
+The sbatch script arguments for running jobs on KNL nodes may differ on CrayXC40
+machines other than mutrino.  The batch scripts knl_ctestS.sl and knl_ctestP.sl 
+have the correct arguments for mutrino:  "#SBATCH -p knl -C quad,cache".  For 
+cori, another CrayXC40, that line is replaced by "#SBATCH -C knl,quad,cache".  
+For cori (and other machines), the values in LOCAL_BATCH_SCRIPT_NAME and 
+LOCAL_BATCH_SCRIPT_PARALLEL_NAME in the config/cmake/scripts/HPC/sbatch-HDF5options.cmake 
+file can be replaced by cori_knl_ctestS.sl and cori_knl_ctestS.sl, or the lines 
+can be edited in the batch files in hdf5-1.11.4/bin/batch.
+
+========================================================================
+V. Manual alternatives
+========================================================================
+If using ctest is undesirable, one can create a build directory and run the cmake 
+configure command, for example
+
+"/projects/Mutrino/hpcsoft/cle6.0/common/cmake/3.10.2/bin/cmake" 
+-C "<working directory>/hdf5-1.11.4/config/cmake/cacheinit.cmake" 
+-DCMAKE_BUILD_TYPE:STRING=Release -DHDF5_BUILD_FORTRAN:BOOL=ON 
+-DHDF5_BUILD_JAVA:BOOL=OFF 
+-DCMAKE_INSTALL_PREFIX:PATH=<working directory>/HDF_Group/HDF5/1.11.4 
+-DHDF5_ENABLE_Z_LIB_SUPPORT:BOOL=OFF -DHDF5_ENABLE_SZIP_SUPPORT:BOOL=OFF 
+-DHDF5_ENABLE_PARALLEL:BOOL=ON -DHDF5_BUILD_CPP_LIB:BOOL=OFF 
+-DHDF5_BUILD_JAVA:BOOL=OFF -DHDF5_ENABLE_THREADSAFE:BOOL=OFF 
+-DHDF5_PACKAGE_EXTLIBS:BOOL=ON -DLOCAL_BATCH_TEST:BOOL=ON 
+-DMPIEXEC_EXECUTABLE:STRING=srun -DMPIEXEC_NUMPROC_FLAG:STRING=-n 
+-DMPIEXEC_MAX_NUMPROCS:STRING=6 
+-DCMAKE_TOOLCHAIN_FILE:STRING=config/toolchain/crayle.cmake 
+-DLOCAL_BATCH_SCRIPT_NAME:STRING=knl_ctestS.sl 
+-DLOCAL_BATCH_SCRIPT_PARALLEL_NAME:STRING=knl_ctestP.sl -DSITE:STRING=mutrino 
+-DBUILDNAME:STRING=par-knl_GCC493-SHARED-Linux-4.4.156-94.61.1.16335.0.PTF.1107299-default-x86_64 
+"-GUnix Makefiles" "" "<working directory>/hdf5-1.11.4"
+
+followed by make and batch jobs to run tests.
+
+To cross-compile on CrayXC40, run the configure command with the craype-haswell 
+module loaded, then switch to the craype-mic-knl module for the build process.
+
+Tests on machines using slurm can be run with 
+
+"sbatch -p knl -C quad,cache ctestS.sl" 
+
+or 
+
+"sbatch -p knl -C quad,cache ctestP.sl" 
+
+for parallel builds.
+ 
+Tests on machines using LSF will typically use "bsub ctestS.lsf", etc.
+
+========================================================================
+VI.    Other cross compiling options
+========================================================================
+Settings for two other cross-compiling options are also in the config/toolchain 
+files which do not seem to be necessary with the Cray PrgEnv-* modules
+
+1.  HDF5_USE_PREGEN.  This option, along with the HDF5_USE_PREGEN_DIR CMake 
+    variable would allow the use of an appropriate H5Tinit.c file with type 
+	information generated on a compute node to be used when cross compiling 
+	for those compute nodes.  The use of the variables in lines 110 and 111 
+	of HDF5options.cmake file seem to preclude needing this option with the 
+	available Cray modules and CMake option.
+
+2.  HDF5_BATCH_H5DETECT and associated CMake variables.  This option when 
+    properly configured will run H5detect in a batch job on a compute node 
+	at the beginning of the CMake build process.  It was also found to be 
+	unnecessary with the available Cray modules and CMake options.
