Dear All,
We are trying to build VASP on 4 node rocks cluster (1master+3 slaves)with each node has two quad core intel processors. We are using mpich. We are using mpif90 compiler. The executable has been made but when we are giving job using the command " mpirun -np 1 vasp" it is running fine.
But the problem comes when we using -np 2 or any higher value than 2 (2-32 we can give by priciple). The problem is it is then running on master only for the no of time we have specified the np but not going to the nodes.

$mpirun -np 4 vasp
and the output is..........

PROBLEM................ :-(
........................ PLEASE HELP..............

The error is probably due to your system (installation mpich, or the setup of your parallel queues). Please ask your system administrator.
Please also check whether the $MPI environment variables are passed on proprerly when your job is executed.

Please check your machines.Linux in your mpich's share folder and if you used torque for pbs and make sure your nodes file for pbs_server specified the machines and their availble procs/cores.
