The code is written in C.  It uses MPI for message passing and it uses BLAS/LAPACK 
for numerical computation. S+ has been tested on SGI Origin 2000, Cray T3E, 
IBM p690 "Regatta", and Linux PC cluster.  You may port it to any other platform 
which also supports MPI and has BLAS/LAPACK library.

We will use them for making  changes in the next release.
