PLASMA 2.4.5 Release
2011-11-22

PLASMA 2.4.5 has been released.

This package contains:

  • Add  LU  inversion functions: PLASMA_zgetri, PLASMA_zgetri_Tile and PLASMA_zgetri_Tile_Async using   the   recursive  parallel  panel implementation of LU factorization.
  • The  householder  reduction  trees for QR and LQ factorizations can now  work on general cases and not only on matrices with M multiple of MB.
  • Matrices  generation  has been changed in every timing, testing and example  files to use a parallel initialization generating a better distribution  of  the data on the architecture, especially for Tile interface. “numactl” is not required anymore.
  • Timing  routines  can  now generate DAGs with the --dag option, and traces with --trace option if EZTRACE is present.

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


PLASMA 2.4.2 Release
2011-09-15

PLASMA 2.4.2 has been released.

This package contains:

  • New version of quark removing active waiting and allowing user to bind tasks to set of cores.
  • Installer: Fix compatibility issues between plasma-installer and PGI compiler reported on Kraken by A. Bouteiller.
  • Fix one memory leak with Hwloc.
  • Introduce a new kernel for the recursive LU operation on tile layout which reduces cache misses.
  • Fix several bugs and introduce new features thanks to people from Fujitsu and NAG :
    • The new LU factorization with partial pivoting introduced in release 2.4 is now working on rectangular matrices.
    • Add missing functions to Fortran 77 interface.
    • Add a new Fortran 90 interface to all LAPACK and Tile interface. Asynchronous interface and mixed precision routines are not available yet.
    • Fix arguments order in header files to fit implementation.

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


PLASMA 2.4.1 Release
2011-07-08

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 Release
2011-06-14

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 Release
2010-11-30

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 )
