Python sayhello Examples

Example #1

from mpi4py import MPI
import helloworld as hw

comm = MPI.COMM_WORLD
fcomm = comm.py2f()
hw.sayhello(fcomm)

Example #2

from mpi4py import MPI
import helloworld as hw

null = MPI.COMM_NULL
hw.sayhello(null)

comm = MPI.COMM_WORLD
hw.sayhello(comm)

try:
    hw.sayhello(list())
except:
    pass
else:
    assert 0, "exception not raised"

Example #3

def get_hello():
    return helloworld.sayhello()

Example #4

File: runme.py Project: Ziaeemehr/mpi_parallel

from mpi4py import MPI
import helloworld

helloworld.sayhello(MPI.COMM_WORLD)
# Hello, World! I am process 0 of 1.
