I'm fascinated to know what the use case is for threads, over separate
processes or (even better) a fully distributed solution like MPI.

Processes scale over NUMA architectures, and MPI (and similar) scales
over clusters.  They are safer and easier to use because all sharing
and synchronization needs to be explicit, and it's more predictable
because factors like false sharing don't come into play.  These
factors are such a win so why would anyone want to use threads?

Rich.
