A UC Berkeley paper [PDF] recently submitted to the IEEE International Parallel and Distributed Processing Symposium manages to highlight two common and seemingly unrelated themes that have come up a number of times over the past few years in my reporting on the high-performance computing (HPC) space: 1) IBM's Cell is really good at HPC workloads when you invest the time to write custom code for it, and 2) Intel's Xeon platform is perennially bandwidth starved and not very power-efficient.
