Introduction
The key to speeding up and optimising a cluster often comes down to its BLAS libraries, so here is a review of what's been doen on the marvin cluster
ATLAS
yum install
This has been done on marvin and all the nodes. It is available in two varieties: normal atlas and then atlas-sse3.
hand compilation
OpenBLAS
Manual compilation is quite straightforward.
make make install PREFIX=/custom/install/path
It is possible to search out th eprecise CPU setting to use and then specify it, but lacking time, no such setting was given and here is the end of the compilation output.
