All I can say is that your program segfault’d during execution - you might want
to look at the core file using a debugger like gdb to see why it failed.

Dear all,
I have successfully compiled a code where the executable have been produced.
However when I started using the executable with mpirun, the code stopped with
the following error:
"mpirun noticed that process rank 0 with PID 570 on node compute-1-9.local

Siegmar,
I will try to reproduce this on my solaris11 x86_64 vm
In the mean time, can you please double check mca_pmix_pmix_pmix112.so is a
64 bits library ?
(E.g, confirm "-m64" was correctly passed to pmix)
Cheers,
Gilles

Dave,
You are absolutely right, the parameters are now 6-7 years old, gathered on
interconnects long gone. Moreover, several discussions in this mailing list
indicated that they do not match current network capabilities.
I have recently reshuffled the tuned module to move all the algorithms in
Thanks for replying, but the difference between what can be done in C vs
fortran is still my problem. I apologize for my rudimentary
understanding of C, but here is a brief summary:
In my originally attached C-program 'testmpi3.c' we have:

I don't know if it's relevant in this case, but that's not generally
true (even for Fortran 77, for which I used to know the st
