To support the compression/decompression abilities embedded in various software products that run on Discoverer, our team compiled and installed an AMD EPIC-optimized version of the Zlib 1.3 library.

It is available in several variants, depending on the compiler used to compile the code, to support the benchmarking and development projects. Intel oneAPI and NVIDIA HPC SDK specific libraries are statically compiled into libz.so. Both AMD AOCC and LLVM build infrastructure LLVM builds are available. GCC build is also installed and available.

The build recipe is publicly available on-line at:
