CosmoCoffee

Hi,
I am trying to compile cosmomc with mpi in a small linux cluster with AMD opteron processors. I am using the intel compiler 8.1. I suspect that with the intel cluster mkl libraries everything woudl be simple. Unfortunately they seem not to be available with a free license and I was wondering if its possible to compile with the mpich libraries instead. In this case I am assuming I will have to compile the mpich libraries with the intel compilers. I actually tried using several of the options in the original cosmomc makefile but they fail. Has anyone tried this before? Is there an easier way to do it?
Thanks in advance for your advice,
Luis

Hi,
I think you can download evalutation versions for both intel mkl, and the intel lmpi library here:
http://www.intel.com/software/products/ ... l_eval.htm
http://www.intel.com/software/products/ ... ds/mpi.htm

The libmpi is quite recent, and I never tested it but I have compiled lammpi with the intel compiler on a xeon cluster without too many difficulties (some modifications in the configure script)

Thanks for the info Christofe. Will try to install mpi from source.
Cheers,
