Subject: Re: [OMPI devel] SM component init unload
From: Juan Antonio Rico Gallego (jarico_at_[hidden])
Date: 2012-07-03 15:24:52


The code I run is a simple broadcast.

When I do not specify components to run, the output is (more verbose):

[jarico_at_Metropolis-01 examples]$ /home/jarico/shared/packages/openmpi-cas-dbg/bin/mpiexec --mca mca_base_verbose 100 --mca mca_coll_base_output 100 --mca coll_sm_priority 99 -mca hwloc_base_verbose 90 --display-map --mca mca_verbose 100 --mca mca_base_verbose 100 --mca coll_base_verbose 100 -n 2 ./bmem

SM is not load because it detects no other processes in the same machine:

[Metropolis-01:24491] coll:sm:init_query: no other local procs; disqualifying myself

The machine is a multicore machine with 8 cores.

I need to run SM component code, and I suppose that raising priority it will be the component selected when problem is solved.
