RE: [Pympi-users] pyMPI interactively

Does pyMPI run correctly when you startup interactively without running
sum.py?

i.e. in your case you should get:

$ mpirun -np 3 pyMPI

Obviously my copy is a later version and on Solaris, but b3 should work
correctly as well. Also, what is inside sum.py?

Subject: [Pympi-users] pyMPI interactively


Greetings pyMPI-users,

I'm working on some major upgrades, moving from pyMPI-1.3a1 running on
RedHat 9 to pyMPI-2.4b3 running Fedore Core 4. I'm running
lam-7.1.1-7.FC4. I'm using rsh on a private network. Once I got the proper
version of rsh running on the machines (had to remove kerberos "rpm -e
krb5-workstation"), most things generally work the same as before. For
example:

[dblank@bw40 mpi]$ mpirun -np 3 pyMPI sum.py
24499996500000

But, I used to be able to also run Python interactively. If I try with the
-i flag, I get an error, or it hangs:

[dblank@bw40 mpi]$ mpirun -np 3 pyMPI -i sum.py
>>>
24499996500000
pyMPI aborting on untrapped fatal signal 11 (SIGSEGV) on rank 0
Fatal Python error: PyThreadState_Get: no current thread
----------------------------------------------------------------------------
-
One of the processes started by mpirun has exited with a nonzero exit
code.  This typically indicates that the process finished in error.
If your process did not finish in error, be sure to include a "return
0" or "exit(0)" in your C code before exiting the application.

PID 28595 failed on node n0 (10.0.0.40) due to signal 6.
----------------------------------------------------------------------------

Has something changed that prevents me from running interactively that
way? I looked through the archives but didn't see anything. Maybe I have
something configure incorrectly?

Thanks for any hints,

-Doug
