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. Here is output for a lazy compilation where the CPU was not specified:
