[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r6252] Purpose: Lots of performance improvements & a couple new internal API interfaces. Description: Performance Improvements: - Cached file offset & length sizes in shared file struct, to avoid constantly looking them up in the FCPL. - Generic property improvements: - Added "revision" number to generic property classes to speed up comparisons. - Changed method of storing properties from using a hash-table to the TBBT routines in the library. - Share the propery names between classes and the lists derived from them. - Removed redundant 'def_value' buffer from each property. - Switching code to use a "copy on write" strategy for properties in each list, where the properties in each list are shared with the properties in the class, until a property's value is changed in a list. - Fixed error in layout code which was allocating too many buffers. - Redefined public macros of the form (H5open()/H5check, <variable>) internally to only be (<variable>), avoiding innumerable useless calls to H5open() and H5check_version(). - Reuse already zeroed buffers in H5F_contig_fill instead of constantly re-zeroing them. - Don't write fill values if writing entire dataset. - Use gettimeofday() system call instead of time() system when checking the modification time of a dataset. - Added reference counted string API and use it for tracking the names of objects opening in a file (for the ID->name code). - Removed redundant H5P_get() calls in B-tree routines. - Redefine H5T datatype macros internally to the library, to avoid calling H5check redundantly. - Keep dataspace information for dataset locally instead of reading from disk each time. Added new module to track open objects in a file, to allow this (which will be useful eventually for some FPH5 metadata caching issues). - Remove H5AC_find macro which was inlining metadata cache lookups, and call function instead. - Remove redundant memset() calls from H5G_namei() routine. - Remove redundant checking of object type when locating objects in metadata cache and rely on the address only. - Create default dataset object to use when default dataset creation property list is used to create datasets, bypassing querying for all the property list values. - Use default I/O vector size when performing raw data with the default dataset transfer property list, instead of querying for I/O vector size. - Remove H5P_DEFAULT internally to the library, replacing it with more specific default property list based on the type of property list needed. - Remove redundant memset() calls in object header message (H5O*) routines. - Remove redunant memset() calls in data I/O routines. - Split free-list allocation routines into malloc() and calloc()- like routines, instead of one combined routine. - Remove lots of indirection in H5O*() routines. - Simplify metadata cache entry comparison routine (used when flushing entire cache out). - Only enable metadata cache statistics when H5AC_DEBUG is turned on, instead of always tracking them. - Simplify address comparison macro (H5F_addr_eq). - Remove redundant metadata cache entry protections during dataset creation by protecting the object header once and making all the modifications necessary for the dataset creation before unprotecting it. - Reduce # of "number of element in extent" computations performed by computing and storing the value during dataspace creation. - Simplify checking for group location's file information, when file has not been involving in file-mounting operations. - Use binary encoding for modification time, instead of ASCII. - Hoist H5HL_peek calls (to get information in a local heap) out of loops in many group routine. - Use static variable for iterators of selections, instead of dynamically allocation them each time. - Lookup & insert new entries in one step, avoiding traversing group's B-tree twice. - Fixed memory leak in H5Gget_objname_idx() routine (tangential to performance improvements, but fixed along the way). - Use free-list for reference counted strings. - Don't bother copying object names into cached group entries, since they are re-created when an object is opened. The benchmark I used to measure these results created several thousand small (2K) datasets in a file and wrote out the data for them. This is Elena's "regular.c" benchmark. These changes resulted in approximately ~4.3x speedup of the development branch when compared to the previous code in the development branch and ~1.4x speedup compared to the release branch. Additionally, these changes reduce the total memory used (code and data) by the development branch by ~800KB, bringing the development branch back into the same ballpark as the release branch. I'll send out a more detailed description of the benchmark results as a followup note. New internal API routines: Added "reference counted strings" API for tracking strings that get used by multiple owners without duplicating the strings. Added "ternary search tree" API for text->object mappings. Platforms tested: Tested h5committest {arabica (fortran), eirene (fortran, C++) modi4 (parallel, fortran)} Other platforms/configurations tested?

[svn-r537] Changes since 19980722 ---------------------- ./src/H5A.c ./src/H5Apublic.h ./test/tattr.c Switched the order of the second and third argument of H5Aget_name() to make it consistent with other functions that take buffers and buffer sizes. ./src/H5G.c ./src/H5Gpublic.h ./src/H5Gprivate.h The H5Gget_comment() function returns the size of the comment including the null terminator. If the object has no comment then zero is returned. If an error occurs then a negative value is returned. ./MANIFEST ./tools/Makefile.in ./tools/h5tools.h [NEW] ./tools/h5dump.c [NEW] Created a library for printing values of datasets in a way that looks nice. It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...

[svn-r537] Changes since 19980722 ---------------------- ./src/H5A.c ./src/H5Apublic.h ./test/tattr.c Switched the order of the second and third argument of H5Aget_name() to make it consistent with other functions that take buffers and buffer sizes. ./src/H5G.c ./src/H5Gpublic.h ./src/H5Gprivate.h The H5Gget_comment() function returns the size of the comment including the null terminator. If the object has no comment then zero is returned. If an error occurs then a negative value is returned. ./MANIFEST ./tools/Makefile.in ./tools/h5tools.h [NEW] ./tools/h5dump.c [NEW] Created a library for printing values of datasets in a way that looks nice. It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...

[svn-r537] Changes since 19980722 ---------------------- ./src/H5A.c ./src/H5Apublic.h ./test/tattr.c Switched the order of the second and third argument of H5Aget_name() to make it consistent with other functions that take buffers and buffer sizes. ./src/H5G.c ./src/H5Gpublic.h ./src/H5Gprivate.h The H5Gget_comment() function returns the size of the comment including the null terminator. If the object has no comment then zero is returned. If an error occurs then a negative value is returned. ./MANIFEST ./tools/Makefile.in ./tools/h5tools.h [NEW] ./tools/h5dump.c [NEW] Created a library for printing values of datasets in a way that looks nice. It's not done yet, but I needed it for debugging the contents of files from Jim Reus. ./tools/h5ls.c Added the `-d' and `--dump' options which cause the contents of a dataset to be printed. Added `-w N' and `--width=N' options to control how wide the raw data output should be. If you want single-column output then say `-w1'. Printing dataset values can now handle datasets of any integer or floating point atomic type. As a special case, integers which are one byte wide are treated a character strings for now. Sample output: $ h5ls --dump --width=60 banana.hdf ARCHIVE 0:0:0:744 Dataset {52/Inf} Data: (0) "U struct complex { double R; double I; };\012V" (43) " double;\012" U 0:0:0:2500 Dataset {256/512} Data: printing of compound data types is not implemented yet V 0:0:0:3928 Dataset {256/512} Data: (0) 0, 0.015625, 0.03125, 0.046875, 0.0625, (5) 0.078125, 0.09375, 0.109375, 0.125, 0.140625, (10) 0.15625, 0.171875, 0.1875, 0.203125, 0.21875, (15) 0.234375, 0.25, 0.265625, 0.28125, 0.296875, ...
