new configuration option tracing/smpi/group
details:
- by default, it is set to 0
- if is 0, the behavior of each MPI process (in the interface
level: MPI_Send, Recv, ...) is not group by host (this means
that you do not know where it was executed by looking only the
trace)
- otherwise, processes are grouped by host
info:
- traditional mpi-focused visualization tools usually do not
group by hosts: that is the reason we are keeping the default value
to 0 (not grouped)
