jd-foster / BLIS.jl

This repo plans to provide a low-level Julia wrapper for BLIS typed interface.

BLIS.jl

This repository provides:

• Wrapper for typed and object-based interface of BLIS.
• Overwrite of LinearAlgebra.BLAS functions so that matrix multiplications can also be redirected to the BLIS backend.
• As BLIS itself is using actively templates and macros, this package also aims to maximize usage of Julia's metaprogramming features.

Performance

Above is a benchmark result obtained against generic-strided matrix multiplications. More performance results are available here.

Installation

]add BLIS.jl

Usage

Basically by using BLIS one replaces LinearAlgebra with BLIS routines as its backends. This should allow direct computation (computation without copying) of generic strided matrices and mixed-datatype matrices. In addition to that BLIS' typed and object-based API are exposed as backends. See documentation for more details.

Roadmaps

• Provide option to compile BLIS into Julia startup image.
• Incorporate HPAC/Linnea in this or another repository.
