AOCL-Sparse is a library that contains basic linear algebra subroutines for sparse matrices and vectors optimized for AMD EPYC family of processors. It is designed to be used with C and C++. Current functionality of sparse library supports SPMV function with CSR and ELLPACK formats.
Sparse for AMD source can be cloned from Github link https://github.com/amd/aocl-sparse. Pre-built AMD optimized Sparse can be installed from the AOCL master installer tar file available under the Download section below.
BLIS is a portable open-source software framework for instantiating high-performance Basic Linear Algebra Subprograms (BLAS) – like dense linear algebra libraries. The framework was designed to isolate essential kernels of computation that, when optimized, immediately enable optimized implementations of most of its commonly used and computationally intensive operations. Select kernels have been optimized for the AMD EPYCTM processor family by AMD and others.
Source code is available on GitHub https://github.com/amd/blis.
FFTW is a comprehensive collection of fast C routines for computing the Discrete Fourier Transform (DFT) and various special cases thereof. It is an open-source implementation of the Fast Fourier transform algorithm. It can compute transforms of real and complex-values arrays of arbitrary size and dimension. An AMD optimized FFTW that includes selective kernels and routines optimized for the AMD EPYCTM processor family is available

AMD LibM is a software library containing a collection of basic math functions optimized for x86-64 processor-based machines. It provides many routines from the list of standard C99 math functions.
Applications can link into AMD LibM library and invoke math functions instead of compiler’s math functions for better accuracy and performance
libFLAME is a portable library for dense matrix computations, providing much of the functionality present in Linear Algebra Package (LAPACK). It includes a compatibility layer, FLAPACK, the FORTRAN interface, which includes complete LAPACK implementation. The library provides scientific and numerical computing communities with a modern, high-performance dense linear algebra library that is extensible, easy to use, and available under an open source license. In combination with the BLIS library which includes optimizations for the AMD EPYCTM processor family, libFLAME enables running high performing LAPACK functionalities on AMD platform.
Source code is available on GitHub https://github.com/amd/libflame.
ScaLAPACK is a library of high-performance linear algebra routines for parallel distributed memory machines. It depends on external libraries including BLAS and LAPACK for Linear Algebra computations. AMD’s optimized version of ScaLAPACK enables using BLIS and libFLAME library that have optimized dense matrix functions and solvers for AMD EPYCTM processor family CPUs.
ScaLAPACK can be installed either from source or pre-built binaries.
ScaLAPACK for AMD source can be cloned from Github link https://github.com/amd/scalapack. Pre-built AMD optimized ScaLAPACK can be installed from the AOCL master installer tar file available under the Download section below.
AMD Random Number Generator Library is a pseudorandom number generator library. It provides a comprehensive set of statistical distribution functions and various uniform distribution generators (base generators) including Wichmann-Hill and Mersenne Twister. The library contains five base generators and twenty-three distribution generators, in addition to hooks for user provided base generator.
The AMD Secure Random Number Generator (RNG) is a library that provides APIs to access the cryptographically secure random numbers generated by AMD’s hardware-based random number generator implementation. These are high quality, robust random numbers that are designed to be suitable for cryptographic applications.
