Hi all,

I'm trying to MPI_Spawn processes with no success.

I'm facing the following error:

=================

All nodes which are allocated for this job are already filled.

==================

I'm setting the hostname as follows:

MPI_Info_set(minfo, "host", hostname);

I'm already running with `--oversubscribe` flag and I've already tried these hostfile:

controller max-slots=1
client     max-slots=3
gateway    max-slots=3
server1    max-slots=41
server2    max-slots=41
server3    max-slots=41
server4    max-slots=41

controller slots=1
client     slots=3
gateway    slots=3
server1    slots=41
server2    slots=41
server3    slots=41
server4    slots=41

 Can anyone help me? Is there a way to force/bypass/disable it?

 I'm running openmpi3/3.1.4 gnu8/8.3.0 from openhpc.

Regards,

Carlos.
