(1) How did you execute it ? mpiexec command line , etc?
any way of a number, does not seem to make any difference. Always on
the command line. I tried mpiexec, mpirun, just running the executable
without wrappers (used to work before, if one wanted to run one single
process). I also tried using a different number of processes, from 1 to 8,
no difference. In any case, if I run the code under gdb (or a graphical
wrapper to gdb, like ddd), I can see that the code hangs when trying to
execute the MPI_Init() call. Or, if I try some of the scalapack example
codes, the first call that implicitly tries to initialise MPI.
(2) Can you give the output of :

And, in case it may help, here goes the output of ldd on the simple "hello
world" MPI code I sent you, that hangs here:

Please let me know whatever I can do to help pinpoint this. I need to be
able to use my computer to develop my MPI codes, and I cannot understand at
all why it abruptly stopped working. Also, if you tell me it does work
properly on another current sid system, I'd like to find out what makes the
difference.
Thanks in advance
