Hello everyone,
I am new to this list and I have a very elementary question: suppose we have
three machines, HN (Head Node hosting the pbs server), WN1 (A worker node) and
WN (another worker node). The PBS nodefile has WN1 and WN2 in it (DOES NOT HAVE
HN).
My openMPI program (hello) and PBS script(my_script.sh) reside on the HN. When
I submit my PBS script using qsub -l nodes=2 my_script.sh, I get the following
error:
--------------------------------------------------------------------------
mpirun was unable to launch the specified application as it could not find an
executable:
Executable: hello
Node: WN2
while attempting to start process rank 0.
--------------------------------------------------------------------------
How come my hello program is not copied automatically to the worker nodes? This
leads to my elementary question:
where the application should be when using a PBS submission?
Note that when I run mpirun from HN with machinefile containing WN1 and WN2, I
get the right output.
Any help on this is very appreciated.
~Belaid.
