AOCL-LibMem is a Linux library of data movement and manipulation functions (such as memcpy and strcpy) highly optimized for AMD Zen micro-architecture. This library has multiple implementations of each function that can be chosen based on the application requirements as per alignments, instruction choice, threshold values, and tunable parameters. By default, this library will choose the best fit implementation based on the underlying micro-architectural support for CPU features and instructions.
This release of AOCL-LibMem library supports the following functions:
- memcpy
- mempcpy
- memmove
- memset
- memcmp
- strcpy
- strncpy
- strcmp
- strncmp
- strlen
INSTALLATION FROM AOCL-LIBMEM GIT REPOSITORY:
After downloading the latest stable release from the git repository, https://github.com/amd/aocl-libmem, follow the steps from the BUILD_RUN.md, to configure and build it for all released AMD Zen CPU architecutres.
Note: Binaries can be built based on the cpu ISA features: AVX2 and AVX512 with help of Cmake flag: ALMEM_ARCH. It is recommended not to load/run the AVX512 library on a non-AVX512 machine as it will lead to crash due to unsupported instructions.
For detailed instructions on how to configure, build, install, please refer to the AOCL User Guide on https://developer.amd.com/amd-aocl
Upstream repository contains LibMem reference manual that has all the information you need to get started with LibMem, including installation directions, usage examples, and a complete API reference.You may also find a copy of the document here on github.
