@mymindd As suggested, I have changed in the code, however another error pops up as below:

Traceback (most recent call last):
File "/home/lokesh/PycharmProjects/mpi/MPI_Multiplication.py", line 118, in
comm.Recv([res1, MPI.FLOAT], source=1, tag=1)
File "mpi4py/MPI/Comm.pyx", line 285, in mpi4py.MPI.Comm.Recv
mpi4py.MPI.Exception: Invalid rank, error stack:
PMPI_Recv(171): MPI_Recv(buf=0x1a5a800, count=20000, MPI_FLOAT, src=1, tag=1, MPI_COMM_WORLD, status=0x1) failed
PMPI_Recv(108): Invalid rank has value 1 but must be nonnegative and less than 1

Can you help me in this?
