Hello,
Thanks for pointing me the location of the problem.
That came from my /dev, and the rights on the files.
I reinstalled linux, and i can now use openmpi correctly.
Still i don't know how i broke badly the system like this....

Ralph Castain a écrit :
Never seen that one before, though we did put the test in there "just
in case".
Basically, this message indicates that the system returned an error
when we attempted to dup2 the stdout/err file descriptors so we could
setup a pipe by which we can forward that output to you.
I have no idea why the system would refuse the request. You might
check your fd limits to see if they are strangely low, or write a
little test program to see if there is something strange about pipe
permissions.
Most likely thing I can think of, though, is that you possibly are
picking up incompatible libraries, or something got crosswise during
build.

Hello all,
I compiled ompi v1.3 (tarball) with the intel compiler on debian
etch. Everything went fine, thanks for the FAQ (quite complet)
But, when i'm running a job, i've got this error :
Trixy03-jobic% mpirun --verbose --debug-daemons -np 4 ./exe
[Trixy03:15140] [[19525,0],0] orted_cmd: received add_local_procs

--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it
encountered an error:
Error: pipe function call failed when setting up I/O forwarding
subsystem
Node: Trixy03
while attempting to start process rank 0.
--------------------------------------------------------------------------
I don't understand what's going on, and how to debug...
I compiled mpich1, and i can successfully launch a job.
Have you got some ideas of what's going on ?
Many thanks,
Yann
