[MITgcm-support] MPI on SGI (irix64_ip35)!

[Van Thinh Nguyen]

Hi,

I tried to compile an example (eg. exp1) with -mpi option. I haven't got
any warming. However, when i run the obtained object file (mitgcmuv) with
command:

mpirun -np 4 ./mitgcmuv

I got an error from STDERR.* that the number of processes must equal
nPx*nPy. I even set nPx=2, nPy=2 and changed the suitable size of number
of tiles in SIZE.h. I also tried to use exch2 pkg by using driver.m in the
utils/exch2/matlab_topology_generator (edited nr,ng,nb; tnx, tny), but the
driver.m didn't work when I ran it on Matlab.

Anyone has any experience on this problem, please help me!

Thanks a lot!
