Just a few thoughts about your problem...

Are the two machines identical in architecture and RH installation? Is there any reason why you cannot compile on the other machine too? (Sometimes the location of dynamic libraries, etc. changes so I try to make a note to always recompile on each machine.) Are you having problems running your program on each node individually first? If not, you might try that first (i.e., with "--np 1").
