[MPICH] Problems with wrong rank and size

[Rajeev Thakur]

Make sure you are using the right mpif.h file with the right MPI
implementation. If you have an mpif.h from one implementation in your
application directory, it will not work if you compile with another
implementation. Similarly, you need to use the mpiexec or mpirun commands
from the MPI implementation you have compiled for.

Subject: [MPICH] Problems with wrong rank and size


Hi,
 
My program in Tomography was actually working well on several cluster pcs
before when I was using (mpich.nt.1.2.5.). But I got a problem with ranking
and size after I installed MPICH2 1.0.3, and uninstalled it since  MPICH2
1.0.3. gave me error messages.
 
There are the details:
When I use mpich.nt.1.2.5., it gives me rank and size like 44468690 or such
a minus number (all the pcs are the same rank and the same size). I checked
all the configuration and installed it again, but it is still this problem.
I am using Digital Visual Fortran. 
 
Could you tell me how can I fix this problem?
 
Thanks,
Maimaitijiang
