| | | | | | | | | | | | | | entry flush callback functions modifies the skip list or LRU out from under a partial or complete flush of the cache. This is a test for a situation that should not occur, but we test anyway. Also added code to skip longer tests in cache_api in express tests. Tested serial and parallel on phoenix (debian --x86-32), and commit test. Elena commit tested as well, and ran a manual test under MacOS X.
* [svn-r14442] Modified metadata cache to adapt more quickly to the insertion of aJohn Mainzer2008-01-181-10/+443
| | | | | | | | | | | | | | | | | large entry, or to a large increases in the size of an existing entry. This required some additions to the cache configuration structure, and thus will require changes in the metadata cache documentation. The basic idea is to monitor the size of entries as they are loaded, inserted, or increased in size. If the size of the entry (or increase) exceeds some user selected fraction of the size of the cache, increase the size of the cache. Note that this fix was designed quickly -- while it deals with the use case that exposed the problem, we may have to revisit the issue later. Tested serial and parallel on Phoenix, and h5committest.

* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-131-8/+375
| | | | | | | | | | | | | | | | | | | | | | 1) Added trace file support to the metadata cache. This allows capture of all metadata cache calls in trace files for purposes of optimization and debuging. 2) Added an expunge entry function. This allows an entry to be deleteded from the cache without writing it to disk even if it is dirty. 3) Added a function call to resize pinned entries. 4) Added code to deal with entries that are dirty on load. This is needed in support of a bug fix which can alter object headers on load to repair files. 5) Added progress reporting code to the "MDC API smoke check" test in cache_api.c. To enable the progress reporting, set report_progress to TRUE in mdc_api_call_smoke_check(). Tested with h5committest, and a parallel test on phoenix (dual athelon linux box).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Check in potential fix to unreproduceable bug in t_cache observed on Cobalt 2) Check in code supporting added pinned entry features in the metadata cache. Description: 1) Elena encountered a bug in t_cache when running on Cobalt. On investigation I found a potential race condition in t_cache that could explain her observation. 2) Quincey requested additions to the metadata cache allowing renaming of pinned entryies, and marking of pinned or protected entries as dirty. Solution: 1) Modified t_cache.c to prevent the potential race condition. Elena was unable to reproduce the bug on Cobalt, so we don't know if my fix actually addressed the problem. 2) Added code supporting the requested functions. The changes were relatively trivial, but required substantial new test code. Platforms tested: h5committest, serial test on heping, parallel test on phoenix. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Repair synchronization bug in the metadata cache in PHDF5 Also repair numerous other bugs that surfaced in testing the bug fix. Description: While operations modifying metadata must be collective, we allow independant reads. This allows metadata caches on different processes to adjust to different sizes, and to place the entries on their dirty lists in different orders. Since only process 0 actually writes metadata to disk (all other processes thought they did, but the writes were discarded on the theory that they had to be collective), this made it possible for another process to modify metadata, flush it, and then read it back in in its original form (pre-modification) form. The possibilities for file corruption should be obvious. Solution: Make the policy that only process 0 can write to file explicit, and visible to the metadata caches. Thus only process 0 may flush dirty entries -- all other caches must retain dirty entries until they are informed by process 0 that the entries are clean. Synchronization is handled by counting the bytes of dirty cache entries created, and then synching up between the caches whenever the sum exceeds an (eventually user specified) limit. Dirty metadata creation is consistent across all processes because all operations modifying metadata must be collective. This change uncovered may bugs which are repaired in this checkin. It also required modification of H5HL and H5O to allocate file space on insertion rather than on flush from cache. Platforms tested: H5committest, heping(parallel & serial) Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | Interim checkin of code changes moving management of the is_dirty flag into the cache code. Description: Prior to this checkin, management of the is_dirty flag was handled above the level of the metadata cache. This can no longer be allowed, as it introduces a race condition in the proposed fix for a cache coherency bug in PHDF5. Solution: Move management fo the is_dirty flag to the cache code proper. Entries are now marked as dirty via a flag on the unprotect call. Platforms tested: h5committested Misc. update:

Description: Prior to this update, the metadata cache was not configurable from outside the library.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1) Provide facilities in cache to allow us to avoid a potential cache consistency bug in the parallel case. 2) Clean up a off by one sanity checking bug. 3) Turn off execution of long running tests in debug mode. Description: 1) In the parallel case, all writes to metadata must be collective, but reads may not be. In pricipal, this allows us to different contents in different caches. This isn't a problem as long as the correct data is always on disk, but unless we can force certain writes immediately, that need not be the case. 2) & 3) should need no further explanation. Solution: 1) Add code allowing us to mark cache entries, and then force these entries to be flushed at a later time. Note that to actually avoid the bug, we will have to modify existing code to use these new features. 2) & 3) should need no further explanation. Platforms tested: heping (serial debug and production) committest (copper, sol, and heping). test failed on heping in the c++ portion of the build, but at Quincey's siggestion, I am proceeding with the checkin.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Bug Fix/Code Cleanup/Doc Cleanup/Optimization/Branch Sync :-) Description: Generally speaking, this is the "signed->unsigned" change to selections. However, in the process of merging code back, things got stickier and stickier until I ended up doing a big "sync the two branches up" operation. So... I brought back all the "infrastructure" fixes from the development branch to the release branch (which I think were actually making some improvement in performance) as well as fixed several bugs which had been fixed in one branch, but not the other. I've also tagged the repository before making this checkin with the label "before_signed_unsigned_changes".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix a bug in the cache caused by a slightly over active sanity check. Description: When the #define H5C_DO_SANITY_CHECKS is TRUE, the macro H5C__DLL_PRE_INSERT_SC is executed prior to inserting an entry in the LRU list. The macro performs a variety of sanity checks, and flags an error if any of the checks fail. Prior to this update, the macro used to check to see if the target list had length 1 and size <= 0. The new epoch marker entries used in the age out cache size reduction algorithm have size zero -- making it possible for this sanity check to fail incorrectly. Note that cache sanity checks are disabled in the CVS version of the code, so this bug and bug fix should be invisible unless you are working with the cache, and turn the sanity checks on. Solution: Removed the offending clause in H5C__DLL_PRE_INSERT_SC. Since the size used in the macro is typically a size_t and thus cannot have negative value, there was no point in changing it to "size < 0". Platforms tested: Ran a serial test on heping. Under the circumstances, I didn't feel the need for further testing. Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modify the cache code (H5C) to support automatic cache resizing to adapt to the work load at run time. Description: Different applications require different sized caches to maintain an acceptable hit rate. This set of changes attempts to provide the ability to adjust to circumstances automatically. Solution: Added highly configurable code to allow the user to either set a fixed cache size, or allow the cache to grow and shrink according to conditions. If enabled, cache size increases are triggered when the hit rate drops below a user specified threshold in a user specified interval. Cache size reductions (if enabled) are triggered when either the hit rate exceeds some user specified threshold over a user specified interval, when the cache contains "enough" entries that haven't been accessed for a user specified interval, or some mix of the above. See the header comments on the H5C_auto_size_ctl_t structure in H5Cprivate.h for further details. At present, the cache resize configuration options are not accessible via the user API. Must add this. Platforms tested: h5committested, heping (serial), and copper (parallel) Misc. update:

* [svn-r9022] Purpose: Optimization of the cache code in H5C.John Mainzer2004-08-051-938/+1663
| | | | | | | | | | | | | | | | | | | | | | | Description: Cache was running too slowly. Solution: Added a hash table for indexing. Retained the tree, but only for dirty entries. As we need to flush dirty entries in increasing address order, this is sufficient. Updated statistics collection code for the above. Converted a number of local functions into macros to avoid the function call overhead. Added code to disable the clean and dirty LRU lists in serial mode. Updated test code to account for the above changes. Platforms tested: h5committested + serial, parallel, and fp on Eirene. Misc. update:

* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+3490
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | performance. Description: Replaced the old metadata cache with a cache with a modified LRU replacement policy. This should improve the hit rate. Solution: Since we want to flush cache entries in increasing address order, I used the threaded binary B-tree code to store the cache entries. There is a fair bit of overhead here, so we may want to consider other options. While the code is designed to allow the support of other replacement algorithms, at present, only a modified version of LRU is supported. The modified LRU algorithm requires that a user selectable portion of the cache entries be clean. The clean entries are evicted first when writes are not permitted. If the pool of clean entries is used up, the cache grows beyond its user specified maximum size. The cache can also exceed its maximum size if the combined size of the protected (or locked) entries exceeds the maximum size of the cache.

Also changed the base names a little to be more accurate as to what they do. The old names H5ACC_WRITE and H5ACC_OVERWRITE will temporarily work. H5ACC_DEFAULT --> H5F_ACC_RDONLY for H5Fopen() H5ACC_DEFAULT --> H5F_ACC_EXCL for H5Fcreate() H5ACC_WRITE --> H5F_ACC_RDWR H5ACC_OVERWRITE --> H5F_ACC_TRUNC Albert or Kim: The H5ACC_INDEPENDENT and H5ACC_COLLECTIVE macros in H5Fpublic.h should be an enum typedef and have names more like H5F_MPIO_INDEPENDENT and H5F_MPIO_COLLECTIVE. Also change the access_mode argument of H5Cset_mpio(). H5Fcreate() and H5Fopen() are more strict now about which flags are acceptable for the operation. ./src/H5Fprivate.h ./src/H5F.c ./src/H5C.c Changed the file access template to make it more general. A union contains a struct for each type of low-level driver and the default template is initialized at run-time. ./src/H5Fpublic.h ./src/H5F.c Added H5Fget_access_template() and cleaned up H5Fget_create_template(). ./src/H5C.c The H5Cset_mpi() no longer trashes the file access template when an error is detected. We check for errors and *then* update the file access template. Added H5C_close() so Albert and Kim have a place to release the MPI communicator and info from the file access property list. Kim or Albert: I notice in H5Cset_mpi() you copy the MPI communicator. Do you need to do something similar in H5C_copy()? ./src/H5F.c Added more error checking for the file creation and access property lists because it used to be possible to make the library dump core by swapping the creation and access property list ID numbers of H5Fcreate(). ./test/istore.c ./test/tfile.c ./test/th5p.c ./test/theap.c ./test/tohdr.c ./test/tstab.c ./testpar/testphdf5.c One must pass H5C_DEFAULT as the file creation or access property list in order to get the default property list.

The "5000 items in a group test" now takes 1.6 seconds. ./src/H5private.h Removed inclusion of mpi.h and mpio.h since they're included from H5public.h. ./src/H5Cpublic.h ./src/H5C.c Added H5Cset_stdio(), H5Cset_sec2(), H5Cset_core(), H5Cset_split(), and H5Cset_family() in addition to the H5Cset_mpio() that Kim and Albert already wrote. We still need the H5Cget_driver() and an H5Cget...() counterpart for each of those functions. The split and family drivers still need a little work but I'm checking this in anyway.

* [svn-r214] Changes since 19980203Robb Matzke1998-02-031-11/+45
| | | | | | | | | | | ---------------------- ./src/H5C.c ./src/H5Cprivate.h ./src/H5D.c ./src/H5Dpublic.h Added H5Dget_create_parms(), trying to stay one step ahead of Elena ;-)
* [svn-r209] Changes since 19980130Robb Matzke1998-01-301-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./INSTALL Added instructions for which C flags to set for debugging. ./src/H5C.c ./src/H5Cpublic.h H5Cset_chunk() takes const pointer. ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h Added H5Dextend() to extend the dimensions of a dataset. ./src/H5Osdspace.c ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h ./test/cmpd_dset.c ./test/dsets.c ./test/th5p.c Added the optional `maxdims' argument to H5Pcreate_simple() and defined constant H5P_UNLIMITED which can appear in the maxdims. Added `const' to arguments. Implemented H5Pcopy() Removed the unused file argument from H5P_modify. Added H5P_extend(). Removed the `flags' field from simple data types and we determine if the `max' or `perm' arrays are valid by looking at the pointer. Cleaned up the H5O_sdspace_debug output. ./src/H5T.c Fixed a printf format. ./MANIFEST ./test/Makefile.in ./test/extend.c [NEW] Added a test for multi-dimensional unlimited dimensions.
* [svn-r193] Changes since 19980128Robb Matzke1998-01-281-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./MANIFEST Added new config files. ./src/H5private.h Changed FUNC_ENTER() so it calls H5Eclear() for all API functions but not for any private functions. It also prints the names of all API functions on file 55 (just for the prototype) so we can get a list of API functions called with the Bourne shell commands like: ./testhdf5 55>api_list or ./testhdf5 55>&1 1>/dev/null 2>&1 | less Otherwise the names are silently discarded. ./src/H5.c ./src/H5C.c ./src/H5D.c ./src/H5F.c ./src/H5G.c ./src/H5M.c ./src/H5P.c ./src/H5T.c Removed `H5ECLEAR' from lots of places in the source code. ./src/H5E.c ./src/H5Eprivate.h Recursion is a problem here, so to disable a call to H5Eclear() from FUNC_ENTER just define a local variable like this before you call FUNC_ENTER: const H5E_clearable_g = FALSE; Unfortunately this results in a warning: declaration of `H5E_clearable_g' shadows global declaration. Good thing it's only used in two places.
* [svn-r188] Changed hbool_t from an enum to 'int' and removed ↵Quincey Koziol1998-01-281-4/+4
| | | | | | | | | | BTRUE/BFALSE/BFAIL from code. Changed interface to the H5P..hyperslab functions to 'int' instead of 'size_t'. Cleaned up lots of warnings on IRIX 6.2 platform. Minor other tweaks to get to a mostly clean build on the SGI. It still whines about 'long long' being non-standard and some "pointless comparison of unsigned with 0" but those aren't big problems.
* [svn-r164] Changes since 19980122Robb Matzke1998-01-221-21/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/*.h Fixed indentation where indent(1) screwed up. This isn't by any means the final say, but it's better than it was. ./src/H5A.c ./src/H5Aprivate.h ./src/H5Apublic.h ./src/H5C.c ./src/H5D.c ./src/H5E.c ./src/H5F.c ./src/H5G.c ./src/H5M.c ./src/H5P.c ./src/H5T.c ./src/H5Tconv.c ./src/debug.c ./test/dtypes.c ./test/istore.c ./test/theap.c ./test/tohdr.c ./test/tstab.c Removed some atom functions from the API and made them library-scope. Also changed some names by removing the redundant `atom' from the name and by adding a `_' after the `H5A'.
* [svn-r159] Changed variables named "template" to "tid" to avoid name clash ↵Quincey Koziol1998-01-201-47/+47

Turn this on to get lots of lines on stderr to show what objects are opened and closed. ./src/H5C.o ./src/H5Cpublic.h ./test/dsets.c ./test/tfile.c Split H5Cget_prop() and H5Cset_prop() into functions for each property. ./src/H5D.c ./src/H5Dpublic.h ./src/H5Gstab.c ./src/H5O.c ./src/H5Ocont.c ./src/H5Ocstore.c ./src/H5Odtype.c ./src/H5Oefl.c ./src/H5Oistore.c ./src/H5Oname.c ./src/H5Onull.c ./src/H5Oprivate.h ./src/H5Osdspace.c ./src/H5Ostab.c ./src/H5P.c ./src/istore.c ./test/tohdr.c Object header functions now understand constant vs. non-constant messages. ./src/H5F.c ./src/H5Fprivate.h The file OID can be closed before other OID's. ./src/H5Flow.c H5F_addr_defined() is a macro in this file. ./src/H5G.c ./src/H5Gpublic.h ./test/tstab.c A current working group cannot be deleted. ./src/H5Gent.c ./src/H5Gpkg.h Removed unused functionality. ./src/H5public.h Includes <sys/types.h> for size_t.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes to error handling. ./src/H5B.c Increased size of internal static buffers. ./src/H5C.c Fixed syntax error when NDEBUG is defined. ./src/H5E.c ./src/H5Eprivate.h ./src/H5Epublic.h Errors can now be printed with H5Eprint(). Other minor changes to names and arg types. ./src/H5F.c The base address is now stored in the boot block. The user block size and the base address are synonyms. ./src/H5Fstdio.c Fixed a bug with a return value from fseek(). ./src/H5H.c Added alignment constraints to get rid of unaligned access errors on the DEC alpha having to do with the heap free list. ./src/H5P.c ./src/H5Ppublic.h Changed some size arguments from int to size_t and fixed memory allocation calls. ./src/H5T.c ./src/H5Tpublic.h Changed the order of functions so all the public ones are at the top of the file. Other minor changes. ./src/H5detect.c Added a newline to a string constant.
