* Added support for vector I/O calls to the VFD layer, and
associated test code. Note that this includes the optimization
to allow shortened sizes and types arrays to allow more space
efficient representations of vectors in which all entries are
of the same size and/or type. See the Selection I/o RFC for
further details.
Tested serial and parallel, debug and production on Charis.
serial and parallel debug only on Jelly.
* ran code formatter
quick serial build and test on jelly
* Add H5FD_read_selection() and H5FD_write_selection(). Currently only
translate to scalar calls. Fix const buf in H5FD_write_vector().
* Format source
* Fix comments
* Add selection I/O to chunk code, used when: not using chunk cache, no
datatype conversion, no I/O filters, no page buffer, not using collective
I/O. Requires global variable H5_use_selection_io_g be set to TRUE.
Implemented selection to vector I/O transaltion at the file driver
layer.
* Fix formatting unrelated to previous change to stop github from
complaining.
* Add full API support for selection I/O. Add tests for this.
* Implement selection I/O for contiguous datasets. Fix bug in selection
I/O translation. Add const qualifiers to some internal selection I/O
routines to maintain const-correctness while avoiding memcpys.
* Added vector read / write support to the MPIO VFD, with associated
test code (see testpar/t_vfd.c).
Note that this implementation does NOT support vector entries of
size greater than 2 GB. This must be repaired before release,
but it should be good enough for correctness testing.
As MPIO requires vector I/O requests to be sorted in increasing
address order, also added a vector sort utility in H5FDint.c This
function is tested in passing by the MPIO vector I/O extension.
In passing, repaired a bug in size / type vector extension management
in H5FD_read/write_vector()
Tested parallel debug and production on charis and Jelly.
* Ran source code formatter
* Add support for independent parallel I/O with selection I/O. Add
HDF5_USE_SELECTION_IO env var to control selection I/O (default off).
* Implement parallel collective support for selection I/O.
* Fix comments and run formatter.
* Update selection IO branch with develop (#1215)
Merged branch 'develop' into selection_io
* Sync with develop (#1262)
Updated the branch with develop changes.
* Implement big I/O support for vector I/O requests in the MPIO file
driver.
* Free arrays in H5FD__mpio_read/write_vector() as soon as they're not
needed, to cut down on memory usage during I/O.
* Address comments from code review. Fix const warnings with
H5S_SEL_ITER_INIT().
* Committing clang-format changes
* Feature/subfiling (#1464)
* Initial checkin of merged sub-filing VFD.
Passes regression tests (debug/shared/paralle) on Jelly.
However, bugs and many compiler warnings remain -- not suitable
for merge to develop.
* Minor mods to src/H5FDsubfile_mpi.c to address errors reported by autogen.sh
* Code formatting run -- no test
* Merged my subfiling code fixes into the new selection_io_branch
* Forgot to add the FindMERCURY.cmake file. This will probably disappear soon
* attempting to make a more reliable subfile file open which doesn't return errors. For some unknown reason, the regular posix open will occasionally fail to create a subfile. Some better error handling for file close has been added.
* added NULL option for H5FD_subfiling_config_t in H5Pset_fapl_subfiling (#1034)
* NULL option automatically stacks IOC VFD for subfiling and returns a valid fapl.
* added doxygen subfiling APIs
* Various fixes which allow the IOR benchmark to run correctly
* Lots of updates including the packaging up of the mercury_util source files to enable easier builds for our Benchmarking
* Interim checkin of selection_io_with_subfiling_vfd branch
Moddified testpar/t_vfd.c to test the subfiling vfd with default configuration.
Must update this code to run with a variety of configurations -- most particularly
multiple IO concentrators, and stripe depth small enough to test the other IO
concentrators.
testpar/t_vfd.c exposed a large number of race condidtions -- symtoms included:
1) Crashes (usually seg faults)
2) Heap corruption
3) Stack corruption
4) Double frees of heap space
5) Hangs
6) Out of order execution of I/O requests / violations of POSIX semantics
7) Swapped write requests
Items 1 - 4 turned out to be primarily caused by file close issues --
specifically, the main I/O concentrator thread and its pool of worker threads
were not being shut down properly on file close. Addressing this issue in
combination with some other minor fixes seems to have addressed these issues.
Items 5 & 6 appear to have been caused by issue of I/O requests to the
thread pool in an order that did not maintain POSIX semantics. A rewrite of
the I/O request dispatch code appears to have solved these issues.
Item 7 seems to have been caused by multiple write requests from a given
rank being read by the wrong worker thread. Code to issue "unique" tags for
each write request via the ACK message appears to have cleaned this up.
Note that the code is still in poor condtition. A partial list of known
defects includes:
a) Race condiditon on file close that allows superblock writes to arrive
at the I/O concentrator after it has been shutdown. This defect is
most evident when testpar/t_subfiling_vfd is run with 8 ranks.
b) No error reporting from I/O concentrators -- must design and implement
this. For now, mostly just asserts, which suggests that it should be
run in debug mode.
c) Much commented out and/or un-used code.
d) Code orgnaization
e) Build system with bits of Mercury is awkward -- think of shifting
to pthreads with our own thread pool code.
f) Need to add native support for vector and selection I/O to the subfiling
VFD.
g) Need to review, and posibly rework configuration code.
h) Need to store subfile configuration data in a superblock extension message,
and add code to use this data on file open.
i) Test code is inadequate -- expect more issues as it is extended.
In particular, there is no unit test code for the I/O request dispatch code.
While I think it is correct at present, we need test code to verify this.
Similarly, we need to test with multiple I/O concentrators and much smaller
stripe depth.
My actual code changes were limited to:
src/H5FDioc.c
src/H5FDioc_threads.c
src/H5FDsubfile_int.c
src/H5FDsubfile_mpi.c
src/H5FDsubfiling.c
src/H5FDsubfiling.h
src/H5FDsubfiling_priv.h
testpar/t_subfiling_vfd.c
testpar/t_vfd.c
I'm not sure what is going on with the deletions in src/mercury/src/util.
Tested parallel/debug on Charis and Jelly
* subfiling with selection IO (#1219)
Merged branch 'selection_io' into subfiling branch.
* Subfile name fixes (#1250)

* Merge branch 'selection_io' into selection_io_with_subfiling_vfd (#1265)
* Added script to join subfiles into a single HDF5 file (#1350)
* Modified H5FD__subfiling_query() to report that the sub-filing VFD supports MPI
This exposed issues with truncate and get EOF in the sub-filing VFD.
I believe I have addressed these issues (get EOF not as fully tested as it should be), howeer,
it exposed race conditions resulting in hangs. As of this writing, I have not been able
to chase these down.
Note that the tests that expose these race conditions are in testpar/t_subfiling_vfd.c, and
are currently skipped. Unskip these tests to reproduce the race conditions.
tested (to the extent possible) debug/parallel on charis and jelly.

* Fixed -Wreserved-id-macro warnings from header include guards
* Removed all __int64 and LL suffix stuff now that C99 is minimum requirement
* Rename `H5FD_CTL__` to `H5FD_CTL_` to fix -Wreserved-id-macro warnings
Double underscore is reserved in C++ and this public header should be C++ compatible.
* Never define __STDC_FORMAT_MACROS anymore
Defining it causes a -Wreserved-id-macro.
Happily, according to the C++11 standard:
"The macros defined by <stdint> are provided unconditionally. In particular, the symbols __STDC_LIMIT_MACROS and __STDC_CONSTANT_MACROS (mentioned in C99 footnotes 219, 220, and 222) play no role in C++."
https://cplusplus.github.io/LWG/issue984
So looks like it's not necessary to define it with reasonably new toolchains.
* Fixed some -Wunused-macros warnings, removed dead code
* Fixed all -Wdouble-promotion warnings in C++ files
* Fixed remaining -Wsuggest-destructor-override warnings
* Committing clang-format changes

H5Pget_fapl_mpio() should return an MPI info object containing all the
MPI-IO hints used by the MPI library underneath, after the file is
opened. Some hints, such as cb_nodes (number of I/O aggregators), are
useful for HDF5 applications and I/O libraries built on top of HDF5.

* Take a stab at using constructors to initialize instead of
function-entry macros. This is a work in progress. It's good enough to
run `many_dsets`.
* Committing clang-format changes
* Add the `many_dsets` benchmark and some scripts I used on jelly for
setting up the build/test environment and for recording/flame-graphing
profiles.
* Committing clang-format changes
* Change my Makefile and environment script to work both on jelly
and on mayll (and probably on Summit).
* Disable clang-format "fix."
* Replace the `if (!H5_TERM_GLOBAL)` test in each FUNC_ENTER_ macro with
`if (true)`.
* Fix bad grammar in a comment.
* Instead of labeling the H5*__init_package routines constructors, fold
each into an initialization routine, H5*_init(), and call each of
the H5*_init() routines. Call most of the H5*_init() routines from
H5_init_library() in an explicit order that I found out earlier by
instrumenting each __init_package routine and running the library
tests. Roll H5FD*__init_package routines into H5FD*_init() routines.
This change ends just-in-time initialization of package dependencies by
package initializers.
Don't track in per-package variables (H5_PKG_INIT_VAR) whether each
package has been initialized. Instead, track in a single library
variable whether the whole library is initialized or not.
Drive the initialization of packages by H5_init_library() with a table
of initializer routines. Also drive the termination of packages by
H5_term_library() with a table.
Perform initialization as needed from FUNC_ENTER_API_INIT(err). This
basically restores the old behavior of that macro.
Delete a bunch of #definitions in H5private.h that have fallen out of
use with these changes.
* Committing clang-format changes
* Undo the bad auto-formatting that appears to have occurred in spite
of my disabling it. Bracket some code in /* clang-format off */ /*
clang-format on */ to prevent a recurrence.
* Remove a diagnostic abort().
* Fix a logic error: print a comma between every package terminator run,
and don't print an initial comma.
* Complete the changes I started in H5_term_library() that undo the bad
auto-formatting.
Stop tracking whether package "tops" were initialized in per-package
variables H5*_top_package_initialize_s. H5_term_library() takes care of
that for them.
Remove H5R_top_term_package() and H5R_term_package(), they don't do
anything.
* Committing clang-format changes
* NFCI. Simplify macro text: replace `if (true) {` with `{`.
* Fix formatting and suppress clang-format on a longer range.
* Quiet some unused label, unused variable complaints that cropped up
after I simplified the FUNC_ENTER_ macros for the sake of performance.
* Committing clang-format changes
* Delete some programs and scripts that don't belong in the pull request.
* Use the right function-entry macro.
* Use a sensible format and disable auto-formatting.
* Stop calling do-nothing initializer H5FS_init(). Delete it.
* Document what changes to make if the default VFD changes.
* While I am here, change an `await_prior` flag on the terminator table
to `true` to match the previous, non-table-driven code that was here.
Found the oversight making the following changes:
NFCI: insert an empty line and copy over slightly-edited comments from
the previous version, where those comments still correctly explained how
library termination operated.
* NFCI: lower a staircase.
* Replace every occurrence of FUNC_ENTER_NOAPI_INIT(...) with H5_PUSH_FUNC
since that is all that that macro does any more.
Quiet a bunch of new warnings by changing FUNC_ENTER_NOAPI(...) to
FUNC_ENTER_NOAPI_NOERR and removing disused `done:` labels.
* NFCI: add curly braces around a multiline statement.
* Quiet a signed/unsigned comparison warning.
* Add some documentation about library initialization and shutdown.
* Make sure that the library is initialized, or else that initialization
is already underway, before performing any VFD's initialization.
* Committing clang-format changes
* Committing clang-format changes
* Reduce differences from `develop` branch.
* Always initialize `tot_init`.
* Committing clang-format changes
* Fix typo: H5SL_init initializes skip lists, not VOL.
* Remove H5_TERM_GLOBAL test in H5T_init. H5T_init was unusual in that
it tested H5_TERM_GLOBAL and exited early if it was set. No other
module initializers did that, and I cannot find any reason that should
be necessary. Tests still pass when I remove it, so away it goes.
* Use HD prefix.
* Add function header comments.
* Drop the intermediate variable, it's only used once.
* Extract subroutine `H5FDperform_init(hid_t (*init)(void))` that
initializes the library, if necessary, before calling its VFD-initializer
argument. Use H5FDperform_init in the definition of the symbols
H5FD_<vfd> (e.g., H5FD_SEC2), which may be evaluated before the library
is initialized, like so:
```
```
I implement H5FDperform_init in its own source file, H5FDperform.c,
and exclude that file from trace processing because the `bin/trace`
cannot deal with the function-pointer type.
* Straggler from last: add new source file src/H5FDperform.c.
* Committing clang-format changes
* Add a missing file to the MANIFEST.
* Switch to FUNC_ENTER_API_NOINIT in H5FDperform_init() and hbool_t in
H5_term_library().

* Added "ctl" callback to the VFD interface, and the associated
H5FDctl() and H5FD_ctl() calls.
Modified the MPIO VFD accordingly -- specifically:
Added ctl() call with op-code support to expose rank, size,
and communicator.
Modified H5FD_mpi_get_rank(), H5FD_mpi_get_size(),
and H5FD_mpi_get_comm() to use the new ctl() callback. In passing
removed the const qualifier from the file parameter of these
functions, as the file parameter of the ctl callback is not
const.
Deleted the old H5FD__mpio_mpi_rank(), H5FD__mpio_mpi_size(), and
H5FD__mpio_communicator() calls from the MPIO VFD.
Deleted H5FD_class_mpi_t from H5FDprivate.h, and modified the
MPIO VFD accordingly. Note that all VFDs now use H5FD_class_t,
with no special class for VFDs that that support MPI.
Some minor touch ups to the Neil's selection I/O mods in passing.
Tested serial and parallel, debug and production on charis and
jelly.
* Reserve a range of VFD "ctl" opcodes for library and experimental usage
* Add "ctl" callbacks to passthrough VFDs
* Add RELEASE.txt entry for "ctl" callback
* Use H5FDopen with H5F_ACC_RDWR flag instead of H5F_ACC_TRUNC in vfd test
* Remove handling of passthrough "ctl" flag from multi VFD
* Move logic for testing H5FD_CTL__TEST_OPCODE into a testing VFD
Revise description of "ctl" callback in RELEASE.txt
Remove unused H5FD_CTL__NUM_OPCODES definition
Fix some warnings in multi VFD

- HDFS VFD files now ignored in the Autotools when the HDFS VFD is not
being built.
- All VFD init code uses idiomatic H5I_INVALID_HID instead of -1
or FAIL.
- The HDFS VFD now includes H5FDdrvr_module.h in the right place.
- The HDFS tests in test/hdfs.c no longer pass NULL to VERIFY macros, which
raised warnings.
- Minor tweaks to fix const, unused variables, etc. warnings in
several VFDs.
