[Pympi-users] pyMPI with mpich2-1.0.4p1 ???

[Jairo S. <jai...@gm...>]

Good Morning !

I dont know if is possible use pyMPI with MPICH2, but i have a problem:

[root@I202-05 mpich2-1.0.4p1]# mpiexec -n 3 pyMPI helloworld.py
I202-05 send the message

and there are no more answers !!!


The machines are Fedora Core 5 on DELL Dimension 3000, 3 CPU's identical:

[root@I202-05 mpich2-1.0.4p1]# uname -a
Linux I202-05 2.6.15-1.2054_FC5 #1 Tue Mar 14 15:48:33 EST 2006 i686 i686
i386 GNU/Linux

pyMPI-2.4b2 and MPICH 2 1.0.4p1 is installed :

[root@I202-05 mpich2-1.0.4p1]# which mpiexec
/usr/local/bin/mpiexec
[root@I202-05 mpich2-1.0.4p1]# which mpicc
/usr/local/bin/mpicc
[root@I202-05 mpich2-1.0.4p1]# which mpd
/usr/local/bin/mpd
[root@I202-05 mpich2-1.0.4p1]# which mpirun
/usr/local/bin/mpirun
[root@I202-05 mpich2-1.0.4p1]# which pyMPI
/usr/bin/pyMPI

Then I got up the mpd daemon:
[root@I202-05 mpich2-1.0.4p1]# mpdboot -n 3
[root@I202-05 mpich2-1.0.4p1]#

i ran mpdtrace and cpi:
[root@I202-05 mpich2-1.0.4p1]# mpdtrace
I202-05
I202-01
I202-04
[root@I202-05 mpich2-1.0.4p1]# mpiexec -n 3 examples/cpi
Process 0 of 3 is on I202-05
Process 1 of 3 is on I202-01
Process 2 of 3 is on I202-04
pi is approximately 3.1415926544231323, Error is 0.0000000008333392
wall clock time = 0.003288

My python program helloworld.py:
-----------------------------------------------
      1 import mpi
      2 from socket import gethostname;
      3
      4 if mpi.rank==0:
      5         print 'message sent by', gethostname()
      6         mens='i am the process'
      7         for i in range(mpi.size):
      8                 mpi.send(mens,i);
      9
     10 else:
     11         msg,status=mpi.recv()
     12         print msg, mpi.rank,' of  ',mpi.size
     13         print 'message received by', gethostname()
-----------------------------------------------


I hope that you could help me !!! thanks a lot !!!
