This repository provides:

- Wrapper for typed and object-based interface of [BLIS](https://github.com/flame/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](docs/src/performance.md).

## 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][docs-dev-url] for more details.

## Roadmaps

- Provide option to compile BLIS into Julia startup image.

- Incorporate [HPAC/Linnea](https://github.com/HPAC/linnea) in this

  or another repository.
