I am using AMD 64 Bit Opteron 8 Dual Core CPU system to set up MM5. I downloaded the Storm of the Century test case and successfully compiled and completed the simulation. However, when doing a more memory intensive run, 275x350x35 at 45 km resolution, no matter my time-step, the model CFL’s shortly after the 3600 seconds or after one model output.
I have looked at previous posts and tried to implement any hints, however, nothing seems to stop my CFL errors. These include unlimited stack, setting the stack to a large number, setting OMP_NUM_THREADS, etc.
Not surprisingly, I have been unable to get the mpi version to work either. Any help / configure.users / or advice from someone that has successfully done MP or MPI would be wonderful.
