These are papers I wrote or contributed to that discuss a Sandia-centric view of the state of parallel computing. I freely admit to a strong distributed-memory message-passing bias. That is, I've never thought the following concepts were that useful in practice: shared-memory machines, SIMD programming methodologies, or automatic parallelizing compilers.
Of course when you work at Sandia with a series of big distributed-memory machines and everyone lives and breathes message passing, you tend to look at the world as one big nail to pound your favorite hammer on!
