[mpich-discuss] Error running with hydra

[Gaetano Bellanca]

Hi,
I'm having problems running a simulation with hydra.
By submitting a job to a queue system (pbs) with the command:

mpiexec-hydra -bootstrap ssh -f machinefile -n number_of_processors 
name_exec

I'm receiving this message:
HYDU_create_process (./utils/launch/launch.c:69): execvp error on file 4 
(Permission denied).

The same code works on the same system using mpd .

Any idea?

Best regards.

Gaetano
