Why would you want your non-primary node workers to have a different verbosity?

[drewj-tp]

Walking through an MPI feature with @zachmprince and we were flummoxed as to why none of the runLog.* messages from the MPI workers were not going into their log files. Some digging in the docs found the branchVerbosity settings that sets the Verbosity of the non-primary MPI nodes

Why would you want this? Presumably your worker nodes are doing things worth logging just like the main node.

Can we remove this setting? Or at least let it inherit or copy from the primary verbosity setting?

I think the only reason is just for reducing file size. If you have a lot of processors all printing at a low verbosity level, the combined run log at the end of a run ends up being unmanageable. Most of the time your error messages are going to show up on the main log, unless you're dealing with an MPI bug.

This is a feature analysts requested I add, to reduce the size and duplication in their log files.

By all means, YOU don't have to use it. But people wanted it, so here it is. #shruf
