Let's make a simple test to figure out where it goes wrong. Create a sample mpi_hello.f90 file with:

PROGRAM HelloWorld
include 'mpif.h'
 
call mpi_init(ierr)
call mpi_comm_size(MPI_COMM_WORLD,npes, ierr)
call mpi_comm_rank(MPI_COMM_WORLD,irank,ierr)
 
print*,'Hello World! I am ',irank,' of ',npes
 
call mpi_finalize(ierr)
 
END PROGRAM

Check that your mpi is in the PATH and LD_LIBRARY_PATH ; compile mpi_hello.f90 with
mpif90 -o mpi_hello mpi_hello.f90

Then run it with
mpirun --mca btl sm,self -np 2 mpi_hello

Do you obtain ...
 Hello World! I am            0  of            2
 Hello World! I am            1  of            2

Hello,

thanks for replying.

1. I went through "ldd abinip" the following message appeared:

although didn't see any unreferenced libraries, I executed "export  LD_LIBRARY_PATH=/usr/local/lib" and configured again, make and make install, I did what you said about making a parallel test and I recievd the following log:
STOP INIT
STOP INIT
