coaster-BLAS provides full BLAS support for Coaster, so you can use Basic Linear Algebra Subprograms on servers, desktops or mobiles, GPUs, FPGAs or CPUS, without carrying about OpenCL or CUDA support on the machine.

coaster-BLAS was started as collenchyma-BLAS at Autumn for the Rust Machine Intelligence Framework Leaf.

For more information,

Getting Started

If you're using Cargo, just add coaster-BLAS to your Cargo.toml:

[dependencies]
coaster = "0.4"
coaster-blas = "0.2.0"

If you're using Cargo Edit, you can call:

$ cargo add coaster-blas

Provided Operations

This Plugins provides the following operations to the Coaster Backend. A - means not yet implemented. More information can be found in the Documentation.

Operation CUDA OpenCL Native
Full Level 1 cuBLAS - rblas
Level 2 - - -
Level 3
GEMM cuBLAS - rblas

Note that blas does not have all methods and thus fails to link, use CARGO_BLAS=openblas to compile for native

Contributing

Want to contribute? Awesome! We have instructions to help you get started contributing code or documentation. And high priority issues, that we could need your help with.

We have a mostly real-time collaboration culture and happens here on Github and on the Coaster Gitter Channel. You can also reach out to the Maintainers {@drahnr}.

Changelog

You can find the release history in the root file CHANGELOG.md.

A changelog is a log or record of all the changes made to a project, such as a website or software project, usually including such records as bug fixes, new features, etc. - Wikipedia

We are using Clog, the Rust tool for auto-generating CHANGELOG files.

coaster-blas's Issues

cublas tests fail

They are not failing all the time, sometimes the first few pass, sometimes they all pass.

error if compute capability < 3.5

Since the minimal compute capbility for CUBLAS is 3.5, the user should best be shown a clear error
if the GPU compute capability is < 3.5

building with `cuda` feature hits `rblas` resolve error

When building juice-examples with cargo build --no-default-features --features cuda, I get an error

error[E0433]: failed to resolve. Maybe a missing `extern crate rblas;`?
  --> /home/erin/.cargo/git/checkouts/coaster-blas-c027954122df0449/2a8f63c/src/transpose.rs:20:33
   |
20 |     pub fn to_rblas(&self) -> ::rblas::attribute::Transpose {
   |                                 ^^^^^ Maybe a missing `extern crate rblas;`?
// etc ... //

I traced this back to the native feature being disabled when I pass these options - and thus this line being compiled out - but this function still trying to reference ::rblas.
