Changelog for memkind-devel-1.6.0-12.1.x86_64.rpm :

* Tue Feb 21 2017 Krzysztof Kulakowski v1.5.0- Intel(R) TBB scalable_allocator can be used as heap management alternative to jemalloc (requires installed Intel (R) TBB package and environment variable MEMKIND_HEAP_MANAGER=TBB)- Updated internally used jemalloc to upstream version 4.3.1 (previously modified 3.5.1)- Introduced new environment option MEMKIND_HOG_MEMORY. Setting it to \"1\" will prevent memkind from releasing memory to OS.- Introduced support for KNM processor from Intel(R) Xeon Phi(TM) family- General cleanup of build scripts (e.g. fixed issues found on Ubuntu, introduced simple build.sh script)- Deprecated support for gigabyte-pages- Removed number of previously deprecated symbols

* Thu Aug 18 2016 Krzysztof Kulakowski v1.2.0- memkind_create() and memkind_ops have been deprecated (moved to memkind_deprecated.h).- Deprecated the headers from memkind/internal and added compile-time warnings to them (plan is to remove those from rpm packages).- autohbw files have been moved to memkind/autohbw directory.- API decorators (memkind_malloc_pre, memkind_malloc_post etc.) now need to be enabled with configure-time option --enable-decorators.- Allocation time optimizations with up to 20% improvement.
* Wed Jul 13 2016 Krzysztof Kulakowski v1.1.1- Performance improvement for memkind_free() in scenario where NULL was passed as kind (reduced by 60%).- Introduced integration with Travis CI.- Fixed issue where memory returned from calloc was not filled with zeroes when using memkind_pmem kinds.- Fixed issue where interleave kinds was failing on systems without Transparent Huge Pages module configured.- Resolved several issues that was causing compilation errors on some systems.- test/test.sh is now able to detect system configuration, and run only those tests which requirements are meet.- Added gtest to repo to avoid downloading it during build proecess.
* Mon May 23 2016 Krzysztof Kulakowski v1.1.0- Implemented algorithm for detecting high-bandwidth memory on Intel Xeon Phi X200 without parsing PMTT.- PMTT-parsing service has been removed.- memkind struct definition from memkind.h has been replaced by forward declaration. Definition has been moved to /internal/memkind_private.h and shouldn\'t be considered as part of library interface anymore.- Performance improvment for hugetlb kinds (check_available() is no longer parsing sysfs every time).- Performance fix by removing --enable-safe from jemmaloc build flags.- New tests for validating high-bandwidth memory detection has been added.- AFTS has been split into two groups: memkind-afts.ts and memkind-afts-ext.ts, based on amount of required memory (for details view test/README).
* Thu Mar 03 2016 Artur Koziej v1.0.0- hbwmalloc.h released as stable API.- Introduce API standards: STANDARD API, NON-STANDARD API, EXPERIMENTAL API.- Introduce memkind versioning API.- Fix type names in hbwmalloc API.- Change error codes to POSIX standard ones in hbwmalloc API.- Move API headers to include directory.- Move NON-STANDARD API, or EXPERIMENTAL API to include/memkind/internal directory.- New man page (memkind_interleave.3) describing interleave kind.- Significant documentation improvement.- Performance fix for jemalloc - significantly decrease of library initialization time.- Enforce 2MB alignment in jemalloc due to the Linux kernel bug (munmap() fails for huge pages, when the size is not aligned).- Move to systemd defined service (memkind.service), drop init.d script.- New rpm layout (memkind and memkind-devel).- Remove false dependency on OpenMP.- Extend test base for stress, longevity and initialization performance tests.- Fix memory leak in ctl_growk().- Rename namespace: hbwmalloc -> hbw.- Rename class: hbwmalloc_allocator -> allocator.
* Thu Oct 15 2015 Krzysztof Kulakowski v0.3.0- Added two new kinds: MEMKIND_INTERLEAVE and MEMKIND_HBW_INTERLEAVE (for details please take a look at man/memkind.3)- Added support for file-backed memory heaps (for details please take a look at man/memkind_pmem.3)- Added autohbw library, that intercepts the standard heap allocations, which let use high-bandwidth memory without modifying existing codebase (for details please take a look at examples/autohbw_README)- jemalloc is now, staticly linked, internal component of memkind RPM instead of rpm dependency.- Added memkind_allocated example which demonstrates usage of memkind with alignas() alignment specifier introduced in C++11 (for details please take a look at examples/README)- Added support for using thread local storage to improve performance in multithreaded applications (enabled by configure time option: --enable-tls)- Added posibility to set number of jemalloc arenas per kind by configure time parameter or enviromental variable (for details please take a look at MEMKIND_ARENA_NUM_PER_KIND section of man/memkind.3).- Added decorators to the memkind allocation APIs. These are weak symbols (pre and post for each API) which can modify the input and output of each of the calls.- Significantly extended test base (new groups of tests: performance, multithreaded, PMTT, nagtive, stress).
* Fri Jan 09 2015 Christopher Cantalupo v0.2.0- Bumped memkind ABI version to 0:1:0.- Removed memkind_get_kind_for_free() from externally facing API\'s. Instead if memkind_free() is called with zero passed for the kind then memkind_get_kind_for_free() is called internally.- Moved to single callback memkind_partition_mmap() to simplify jemalloc modifications.- Added hooks for setting file descriptor and offset for mmap enabling file-backed memory kinds.- Added a void pointer called \"priv\" to memkind structure for storing data for user-defined kinds.- Removed call to sched_getcpu(), now thread id is hashed to determine the arena index.- Added weak symbol hooks for decorating the heap management functions.- Fixed several issues with init.d/memkind script and spec file scriptlets that are exposed by SLES-12.- Introduced an example library called numakind. The numakind library will allocate from the closest NUMA node to a thread as measured when that thread makes its first allocation call.- Fixed error handling in memkind_gbtlb_mmap() that could cause a segfault when gigabyte pages are not available.- Added tests for PMTT parser.- Removed binary mock PMTT table from source code, replaced it with a hexdump.- Fixed a number of issues in test scripts which were suppressing errors.- Removed unnecessary includes from header files.- Better error checking in example code.- Documentation update and clean up.
* Thu Nov 13 2014 Christopher Cantalupo v0.1.0- Increased test code coverage significantly.- Fixed bug in memkind_error_message() for MEMKIND_ERROR_TOOMANY.- Removed memkind_arena_free() API since it was redundant with memkind_default_free().- Static memkind structs are now declared as extern in the headers and defined in the source files files rather than being statically defined in the headers.
* Thu Oct 30 2014 Christopher Cantalupo v0.0.9- Now building with autotools.- Updated documentation.- Fixed typo in copyright.- Fixed test scripts to properly handle return code of each test.- Added C++03 standard allocator that uses hbw_malloc and hbw_free.
* Tue Sep 30 2014 Christopher Cantalupo v0.0.8- Added GBTLB functionality, code clean up, documentation updates, examples directory. Examples includes stream modified to use memkind interface. Code coverage still lacking, and documentation incomplete.
