XK.jl - Julia bindings for the XKRT and XKBlas softwares

XKRT is a macro-dataflow and tasking runtime system for automating memory management alongside parallel execution. It provides portable abstraction for C, C++, Julia and partial support for BLAS and OpenMP. Please see the XKRT Repository for more information.

This package is the Julia API of the XKRT environment. It currently exposes the XK.BLAS module: a composable, performant and portable multi-GPU BLAS library. Other modules are experimental.

Installation

XK.jl must currently be installed manually, please use the following steps.

Prerequisities

• Julia >= 1.11
• CMake >= 3.17
• A C++20 compatible compiler (LLVM/clang >= 20.x recommended)
• hwloc library

Steps

• Edit the header of deps/build_xkblas.jl to your convenience
• Be sure to be using a C++20 compatible compiler (i.e., maybe export CC=clang CXX=clang++)
• Run julia --project=./deps -e 'using Pkg; Pkg.instantiate(); include("./deps/build.jl")'

Testing

If the installation succeeded, this should run:

julia examples/blas/gemm.jl

You can run exhaustive tests with

julia --project -e 'using Pkg; Pkg.test()'

Usage

See examples/ for more examples.
