I have two quad core machines(Having Fedora(11-12) fully updated as OS) and i use them for running parallel programs using mpirun. Now if i use all 4 cores the process hangs within some 800 iterations alsmost 15-20 minutes on both the machines but if i run it using 3 cores it continues to run for days.
It just hangs showing 100% processor usage for all processors and no output. Has anyone experienced the same problem. Any suggestions in this regard will be very useful.
I dont know weather its a hardware or a software problem.
