I made a second check on initialization of PETSc, and found that the
initialization does not take effect. The codes are as follows.
call PetscInitialize(Petsc_Null_Character,ierrcode)
call MPI_Comm_rank(Petsc_Comm_World,rank,ierrcode)
call MPI_Comm_size(Petsc_Comm_World,nprcs,ierrcode)
The value of rank and nprcs are always 0 and 1, respectively, whatever
how many processors are used in running the program.
The most common reason for this is that you have more than one MPI
implementation on your system and they are getting mixed up.
Yes, I have MPICH2 and Microsoft HPC on the same OS. The PETSc was build
using MPICH2. I will uninstall Microsoft HPC to see if it works.
Thanks,
