problems with increasing the number of processors

[pavel_fayman]

Dear Colleagues. Can anyone suggest what the problem might be.

When i use 60 proc or less, for example:
mpirun -np 60 romsM jes.in
it work well.

when i increase the number of processors, for example: mpirun -np 70 romsM jes.in
result is:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Did you set NtileI and NtileJ in the .in file correctly (NtileI x NtileJ = nproc)?

Does the system you're using have that many processors, or allow you to use that many processors?

I've also run into a problem before when a core on a node on a supercomputer was down (16 cores per node, but one didn't work). Are you able to see which nodes/cores you're using?

If none of these, could you provide some model setup info (resolution, etc.) and system info (number of available processors, RAM, etc.) that could help diagnose the problem?
