In situ fragment detection at scale

We explore the problem of characterizing fragments using Par-aView in situ with an explosion simulation. By running in situ we can see a much higher temporal view of the data as well as potentially compress the output to only those statistics about fragments we care about. However, the fragment finding must be able to scale as well as the simulation. In order to achieve the necessary scales, we borrow operations the simulation is already doing and take advantage of them within Para View, demonstrating the resulting improvement in scaling performance.
