[Users] Failure to run static_tov simulation using more than 1 node on cluster

[Steven R. Brandt]

If your ini file is not part of the simfactory checkout (i.e. we don't 
know about it), you may have to edit by hand. I think simfactory 
attempts to run lscpu to determine some of these parameters, but if it 
is not present 1 may be the default.

If you are part of a group, it may be beneficial to have your ini file 
checked in to simafactory (after it is debugged and tested) so that 
other members of your group have access to it. We can help make that happen.
