PLASMA 2.4.1 has been released.

This package contains two major bug fix:

• Fix bug with Fujitsu compiler reported on the forum
• Unbind threads in PLASMA_Finalize to avoid problem of binding in OpenMP section following PLASMA calls (still possible on Mac and AIX without hwloc). A better fix is to create the OpenMP thread in the user code before any call to PLASMA thanks to a fake parallel section.

All files are available for download in the Software section of the PLASMA site.

PLASMA 2.4.0 has been released.

This package contains several new important routines:

• LAPACK-compliant LU factorization,
• symmetric eigenvalue problem routines (eigenvalues only, no eigenvectors yet),
• singular value decomposition routines (singular values only, no singular vectors yet),
• generalized eigenvalue problem routines (symmetric positive definite systems only),
• tree-based QR and LQ routines supporting all input parameters Left/Right, NoTrans/Trans/ConjTrans.

All files are available for download in the Software section of the PLASMA site.

PLASMA 2.3.1 has been released.

This package contains only several minor bug fixes:

•  Add  functions to generate random matrices (plrnt, plghe and plgsy)
  ⇒ fix the problem with time_zpotri_tile.c reported by Katayama on the forum.
• Fix a dead lock in norm computations with static scheduling.
• Installer: fix the LAPACK version when libtmg is the only library to be installed.
  Thanks to Henc. ( forum )

PLASMA 2.3.0 has been released.

The new functionality includes:

• Explicitly calculating an inverse of a matrix using Cholesky factorization (symmetric positive definite)
• Tree-bases QR factorization and Q matrix generation for tall and skinny matrices

Thanks to Julien Langou and Henc Bouwmeester for providing the Cholesky inversion code.

This release also includes parallel and cache-efficient in-place matrix layout translation routines provided by Fred Gustavson and Lars Karlsson. From this point on, PLASMA can switch between LAPACK layout and PLASMA's native tile layout without any memory overhead.

Thanks Fred and Lars!

Also a binary installer for 64 bit PLASMA libraries has been released for Windows x86_64.  It includes statically compiled PLASMA libaries, and testing executables. Use of the PLASMA libraries requires a C compiler (e.g. MS VC, Intel C compiler) and a BLAS library (e.g. Intel MKL, AMD ACML).  Reference versions of LAPACK, BLAS, and other required libraries are included in this binary package for simple testing purposes, but optimized math libraries should be used for any real work.

All files are available for download in the Software section of the PLASMA site.

Any question, issues, complaints, and suggestions can be posted on the PLASMA forum.

Best regards from the PLASMA development team and all those who helped with this release.

The newest release of PLASMA, version 2.2.0, and the PLASMA Installer, version 1.2.0, is available from the Software section of the PLASMA website.
