Hi @wsmoses : I'm using something weird built on top of RHEL7, in a place where I don't have root. But I'll wait until the next iteration, probably smarter to...

Very cool. Should I wait for the listed commits to land, or is there a dummy's guide I could look at to help me take this for a spin?

Hey Tom, You might want to take a look at the work we've been doing in #10 (improved in #13 with your suggestions). The RegexFilter implements what you wanted there,...

We haven't benchmarked it yet, but I can't imagine it's anything less than terrible to be honest, it's just the std regex evaluated each time on a begin or end,...

Until I get in Monday, it appears to be [compiled every time](https://github.com/LLNL/Caliper/blob/master/src/common/filters/RegexFilter.h#L24). @davidbeckingsale

Hold off on merging this one, there's something we ought to discuss

Okay, so I think I'll write the logic as follows: 1) If we're using CUDA, and doing a cuda-activity-report, then no fencing is needed. 2) Otherwise, do global fencing And...
