I'm afraid you're right... I was testing it with Open MPI on my laptop, but later on the cluster I had some problems... Probably a colleague has uploaded mpich...
But I thought the behavior I see might be "implementation-independant". Probably sounds stupid... :)
Thanks anyway :)

Hello everyone!
I am trying to run 11 instances of my program on 6 dual-core Opterons
(it is not time-consuming application anyway, takes 10 seconds at
one-core laptop :)).
so, when I type:
mpiexec -machinefile hostfile -n 11 ./program
nothing happens!
The output of:
"mpdtrace -l" command (from the machine I type the command at) is:
lx64a171_41469 (10.156.70.171)
lx64a176_47945 (10.156.70.176)
lx64a175_42990 (10.156.70.175)
lx64a174_39601 (10.156.70.174)
lx64a173_45387 (10.156.70.173)
lx64a172_55297 (10.156.70.172)
(seems that all 6 machines are there)
Does anyone have any idea/clue what the reason could be?
Thanks in advance!
Regards,
Jovana

Hate to say this, but you don't appear to be using Open MPI.
"mpdtrace" is an MPICH command, last I checked.
You might try their mailing list, or check which mpiexec you are using
and contact them.
