As far as my experience goes, I've been running SIESTA on a 64-processor SMP by Hewlett-Packard. Everything was okay, although using MPI on an SMP is certainly a waste of memory. There's indeed no difference for SIESTA between an SMP and a cluster.

Hi Thomas, More details, such as compiler, mpi flavor, libraries, etc., would definitely be useful. However, I have been using siesta on my dual-core laptop without problems. Not as impressive as a 16-processed machine, but it's a SMP machine anyway :) I remember I had trouble using lam-mpi, but I don't remember if it was at compile time or run time. When I switched to mpich, everything worked fine. Regarding compiling instructions, there is no difference, as far as I know, from compilation in a cluster or smp machines. Any of the how-to's available will do the job. Marcos > Hello all,Our research group has recently invested in an SMP machine with > 16 processors.
