MPI, PVM or PVFS???????

[Luis Fernando Licon Padilla]

I'm trying to build a beowulf cluster for numerical simulation purposes, 
I've got 7 nodes with 2 pentiums III each one, SCSI hard disks, and 
256Mb of RAM (Master node got 512Mb of RAM) on a 3COM fast ethernet 
switch.  I've configured NFS and NIS under RedHat Linux 7.0 as a private 
network for the moment. Now, my question is: what interface such MPI or 
PVM do I need?

Hope somebody can help me,

Thanks in advanced,
