New PLASMA v2.3.0 and the PLASMA Installer v2.3.0 released!

PLASMA 2.3.0 Release
2010-11-16
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 here on the PLASMA forum.

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

All,

Users who do not have the Matrix generation function as part of their Lapack library and decide to download the netlib LAPACK will need to alter the file script/tmg.py. It points to the previous version of Lapack (3.2.2).

tmg.py line 154 needs to be changed from
os.chdir(os.path.join(os.getcwd(),'lapack-3.2.2'))
to
os.chdir(os.path.join(os.getcwd(),'lapack-3.3.0'))

Once that is done, the installation should proceed as normal.

Regards,
Henc

The PLASMA installer has just been updated to work with the last release of CBLAS.
