@Gus, Eugene I read all you mails and even followed the same procedure, it was blas that was giving the problem.
Thanks I am again stuck on a problem, i connected a new node to my cluster and installed CentOS 5.2 on it. after that i use yum to install openmpi,openmpi-libs and openmpi-devel sucessfully. But still when i run mpicc command it gives me error : *bash: mpicc: command not found* i found out there is a command *mpi-selector* but dont know hoe to use it. Is this a new version of openmpi? how do i configure it?
