I see. No, we don't copy your envars and ship them to remote nodes. Simple
reason is that we don't know which ones we can safely move, and which would
cause problems.
However, we do provide a mechanism for you to tell us which envars to move.
Just add:
-x LD_LIBRARY_PATH
to your mpirun cmd line
My apologies for not being clear. These variables are set in my
environment, they just are not published to the other nodes in the
cluster when the jobs are run through the scheduler. At the moment,
even though I can use mpirun to run jobs locally on the head node
without touching my environment,
Normally, one does simply set the ld_library_path in your environment to
point to the right thing. Alternatively, you could configure OMPI with
--enable-mpirun-prefix-by-default
This tells OMPI to automatically add the prefix you configured the system
with to your ld_library_path and path envars.
Thanks for the quick reply. This leads me to another issue I have
been having with openmpi as it relates to sge. The "tight
integration" works where I do not have to give mpirun a hostfile when
I use the scheduler, but it does not seem to be passing on my
environment variables. Specifically beca
I'm afraid we have never really supported this kind of nested invocations of
mpirun. If it works with any version of OMPI, it is totally a fluke - it
might work one time, and then fail the next.
The problem is that we pass envars to the launched processes to control
their behavior, and these confl
Hello,
I am having trouble with a script that calls mpi. Basically my
problem distills to wanting to call a script with:
mpirun -np # ./script.sh
where script.sh looks like:
#!/bin/bash
mpirun -np 2 ./mpiprogram
Whenever I invoke script.sh normally (as ./script.sh for instance) it
works fine, b
