So to be clear: each parent launches 10 children, and no other parents
participate in that spawn?
And there is no threading in the app, yes?

Ken,
Why are the qsub ncpus and mpiirun -np different values.

Hello Ken
: [OMPI users] orted segmentation fault in pmix on master
Hello Ken,
Could you give the details of the allocation request (qsub args) as well as the
mpirun command line args? I'm trying to reproduce on the nersc system.
It would be interesting if you have access to a similar size non-cray cl
Won't help him. aprun does not support dynamics.

Hello Ken,
Could you give the details of the allocation request (qsub args)
as well as the mpirun command line args? I'm trying to reproduce
on the nersc system.
It would be interesting if you have access to a similar size non-cray
cluster if you get the same problems.

I don’t have a Cray, but let me see if I can reproduce this on something else

Hello,
I am attempting to use the openmpi development master for a code that uses
dynamic process management (i.e. MPI_Comm_spawn) on our Cray XC40 at the
Army Research Laboratory. After reading through the mailing list I came to
the conclusion that the master branch is the only hope for getting t
20 matches
