* [svn-r19622] Port of fix for the round robin parallel flush bug caused by ↵John Mainzer2010-10-171-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | the failure of the H5Ocache.c code to update its image of the on disk representation of the object header on a call to the clear callback. This wasn't an issue as long as all flushes of the object header were made from the same process, but if an object header is modified, and then flushed on one process and cleared on the rest, the changes were not be reflected in the images of the on disk representation on all processes where the object header was cleared rather than flushed. If one of these processes did the next flush, the changes were lost in the on disk representation. Fixed this by causing all dirty messages and to be written to the copy of the on disk image maintained by the object header code on both flush and clear. Also added associated test code in t_mdset.c. Also checking in some cache debug code developed while chasing this bug. Commit tested and tested (parallel) on phoenix.

| | | | | | | | | | | | | | | | | | | | | | | Commit metadata tagging framework. Description: This check-in contains a new framework whose goal is to apply a tag value to each new entry in the metadata cache as it is created. This tag value is such that it relates each piece of metadata to the HDF5 object that it belongs to (dataset, group, et cetera). This changeset includes the framework that applies the tags as well as a suite of tests to verify correct tag application, though does not yet make use of the tag values to flush/evict individual objects. Please refer to the "flush/evict individual objects" RFC for further discussion of these changes. Tested: jam, amani, linew (h5committest) liberty, abe, blue print

| | | | | | | | | | | | | | | | | 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.

Failed on osage with a configuration error that appears unrelated to my changes. Serial test (debug mode) passes on Phoenix (Linux x86 2.6 kernel), so I went ahead with the checkin.

| | | | | | | | | | | | | | | | | handle flush callbacks which can dirty other entries, and resize and/or rename the target entry. This feature is needed by the fractal heap code. Also added associated test code. H5Commit tested. Test failed on heping, but the error appears to be a syntax error in an un-related file. Tests on copper & sol passed, along with tests on phoenix.
* [svn-r12595] Modified H5C_insert_entry() to accept the H5C__PIN_ENTRY_FLAG entryJohn Mainzer2006-08-171-12/+35
| | | | | | | | | | | flag, and pin an entry as it is inserted. The objective is to avoid some function call overhead in fheap. Also added matching test code in test/cache.c & test/cache_common.c (also testpar/t_cache.c checked in separately by accident) h5commit tested
* [svn-r12462] Committed a variety of metadata cache related changes:John Mainzer2006-07-131-0/+18
| | | | | | | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | | | | | | Add pinned entry capability to cache. Description: For frequently accessed cache entries, the protect/unprotect overhead is sometimes a bottleneck. Solution: Allow entries to be pinned in the cache. Pinned entries can't be evicted, but can be flushed or modified. Platforms tested: h5committested -- minus one small typo in test/cache.c whose fix was tested on copper and heping only. 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:

| | | | | | | | | | | | | | | | | | | | | | | | | | Add API calls allowing user control of the metadata cache. Description: Prior to this update, the metadata cache was not configurable from outside the library. Solution: Add API calls allowing the user to configure the metadata cache either at file open time, or for any open file. Also added calls permitting the user to monitor cache size and hit rate. These latter facilities are needed for "manual" cache size control Platforms tested: h5committested Misc. update:

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

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".

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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:

| | | | | | | | | | | | | | | | | | | | | | | 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.

* [svn-r8791] Purpose: Rewrote metadata cache (H5AC.c, etc.) to improve ↵John Mainzer2004-07-021-0/+374
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
