Hi all I have just uploaded MPACK 0.8.0RC2 http://sourceforge.net/projects/mplapack/files/mpack/mpack%200.8.0/mpack-0.8.0-RC2.tar.gz/download https://sourceforge.net/projects/mplapack/files/mpack/mpack%200.8.0/mpack-0.8.0-RC2.tar.gz/download . MD5 (mpack-0.8.0-RC2.tar.gz) = c2aa0cf512a5dfcf2881c69f70953c02 Build fixes. Build and make check have passed on * Intel Composer 13.0.1 on Linux. * Gcc on Linux (Ubuntu, RedHat) * gcc47 on FreeBSD * gcc46 on MacOSX Lion * CUDA 3.1, 3.2, 4.0, 4.2, 5.0 on Linux Host Best, Nakata Maho From: Maho NAKATA <ma...@ri...> Subject: MPACK 0.8.0 RC1 : CUDA support for Rgemm in double-double precision.
