AOCL is a set of numerical libraries optimized for AMD processors based on the AMD “Zen” core architecture and generations. Supported processor families are AMD EPYC™, AMD Ryzen™, and AMD Ryzen™ Threadripper™ processors. The tuned implementations of industry-standard math libraries enable rapid development of scientific and high-performance computing applications.

AOCL.jl is a Julia package that allows users to use the AMD AOCL libraries for Julia's underlying BLAS and LAPACK, instead of OpenBLAS (default).

This is made possible by libblastrampoline, which enables picking a BLAS and LAPACK library at runtime.

Adding the package will replace the system BLAS and LAPACK with AOCL provided ones at runtime. Note that the AOCL package has to be loaded in every new Julia process. Upon quitting and restarting, Julia will start with the default OpenBLAS.

julia> using Pkg;
julia> Pkg.add(url="https://github.com/amd/AOCL_jll.jl");
julia> Pkg.add(url="https://github.com/amd/AOCL.jl");

It is important to have AOCL_jll installed before installing AOCL.jl, as the latter depends on the former.

Note: The package is only available on Linux at the moment.
