Summary of Current Features

     * Solution  of  dense  systems  of  linear equations and least square
       problems in real space and complex space using single precision and
       double precision via the Cholesky, LU, QR and LQ factorizations
     * Solution  of  dense  linear  systems of equations in real space and
       complex  space  using  the  mixed-precision  algorithm based on the
       Cholesky, LU, QR and LQ factorizations
     * Generation  and  application  of the Q matrix resulting from the QR
       and LQ factorizations
     * Tree-based  QR  factorization  and Q matrix generation (“tall and
       skinny”)
     * Explicit   matrix   inversion   based   on  Cholesky  factorization

     * Parallel   and   cache-efficient   in-place   layout   translations
       (Gustavson et at.)
     * Complete  set  of Level 3 BLAS routines for matrices stored in tile
       layout
     * Simple  LAPACK-like interface for greater productivity and advanced
       (tile) interface for full control and maximum performance; Routines
       for  conversion  between  LAPACK  matrix layout and PLASMA’s tile
       layout
     * Dynamic  scheduler  QUARK  (QUeuing  And  Runtime  for Kernels) and
       dynamically   scheduled  versions  of  all  computational  routines
       (alongside statically scheduled ones)
     * Asynchronous interface for launching dynamically scheduled routines
       in  a  non-blocking  mode.  Sequence  and  request  constructs  for
       controlling progress and checking errors
     * Automatic handling of workspace allocation whenever possible; A set
       of   auxiliary   functions   to  assist  the  user  with  workspace
       allocation, where necessary
     * A simple set of "sanity" tests for all numerical routines including
       Level 3 BLAS routines for matrices in tile layout
     * An  advanced  testing suite for exhaustive numerical testing of all
       the  routines  included  in the package in all precisions (based on
       the testing suite of the LAPACK library)
     * Basic  timing  code  for  the  solution of linear systems and least
       square problems using Cholesky, LU, QR and LQ factorizations in all
       precisions for input matrices in LAPACK layout and in tile layout
     * Thread safety
     * Support for Make and CMake build systems
     * LAPACK-style comments in the source code using the Doxygen system
     * Native  support  for  Microsoft  Windows using WinThreads through a
       thin OS interaction layer
     * Installer capable of downloading from Netlib and installing missing
       components of PLASMA’s software stack (BLAS, CBLAS, LAPACK, LAPACK
       C Wrapper)
     * Extensive documentation including Installation Guide, Users' Guide,
       Reference  Manual  and  an  HTML  code  browser, a guide on running
       PLASMA  with  the  TAU  package,  Contributors' Guide, a README and
       Release Notes.
     * A comprehensive set of usage examples

New Features by Release

  2.3.1, November 30th, 2010

     * Add  functions to generate random matrices (plrnt, plghe and plgsy)
       ⇒ fix the problem with time_zpotri_tile.c reported by Katayama on
       the forum
       ([1]http://icl.cs.utk.edu/plasma/forum/viewtopic.php?f=2&t=59)
     * Fix a dead lock in norm computations with static scheduling
     * Installer:  fix  the LAPACK version when libtmg is the only library
       to be install Thanks to Henc.
       ([2]http://icl.cs.utk.edu/plasma/forum/viewtopic.php?f=2&t=60)

  2.3.0, November 15th, 2010

     * Parallel   and   cache-efficient   in-place   layout   translations
       (Gustavson et al.)
     * Tree-based  QR  factorization  and Q matrix generation (“tall and
       skinny”)
     * Explicit   matrix   inversion   based   on  Cholesky  factorization
       (symmetric positive definite)
     * Replacement of LAPACK C Wrapper with LAPACKE C API by Intel

  2.2.0, July 9th, 2010

     * Dynamic  scheduler  QUARK  (QUeuing  And  Runtime  for Kernels) and
