The code I run is a simple broadcast.
When I do not specify components to run, the output is (more verbose):

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.
