Parallel Linear Algebra Software for Multicore Architectures

University of Tennessee (US)

University of Manchester (UK)


PLASMA is a software package for solving problems in dense linear algebra using multicore processors and Xeon Phi coprocessors. PLASMA provides implementations of state-of-the-art algorithms using cutting-edge task scheduling techniques. PLASMA currently offers a collection of routines for solving linear systems of equations, least squares problems, eigenvalue problems, and singular value problems.

PLASMA is in the process of porting form QUARK to OpenMP. At the same time, it is moving from its ICL SVN repository to this Bitbucket Mercurial repository. The content of this repository reflects the progress of the transition. Before the transition is complete, the last release of the old PLASMA is available here: https://bitbucket.org/icl/plasma/downloads/plasma_2.8.0.tar.gz


One way to get PLASMA is to clone the repository. Click the Clone tab in the navigation bar on the left. Typically, the command is hg clone ssh://hg@bitbucket.org/icl/plasma

Alternatively, click the Downloads tab in the navigation bar, and then the Tags tab, to download the current state of the repository (the tip), or any of the numbered releases, as a zip, gz, or bz2 archive.


Doxygen-generated PLASMA documentation is available at: http://icl.bitbucket.io/plasma/doxygen/
