XKBLAS

Keywords: BLAS - Dense linear algebra - GPU

Functional Description: XKBLAS is yet an other BLAS library (Basic Linear Algebra Subroutines) that targets multi-GPUs architecture thanks to the XKaapi runtime and with block algorithms from PLASMA library. The library offers a wrapper library able to capture calls to BLAS (C or Fortran). The internal API is based on asynchronous invocations in order to enable overlapping between communication by computation and also to better composed sequences of calls to BLAS.

This current version of XKBlas is the first public version and contains only BLAS level 3 algorithms, including XGEMMT:

XGEMM XGEMMT: see MKL GEMMT interface XTRSM XTRMM XSYMM XSYRK XSYR2K XHEMM XHERK XHER2K

For classical precision Z, C, D, S.

Release Functional Description: XKBlas has following limitations:

0.1 versions: calls to BLAS kernels must be initiate by the same thread that initializes the XKBlas library.
