Parallel Object Oriented Methods and Applications: LOS Alamos' approach to doing parallel scientific computing by using high-level object descriptions of operations. The aim is high portability: express the work to be done conceptually in this way, and you can debug on a workstation, but run immediately on a massively parallel computer. Currently does things like particle plasma simulations on the DOE ASCI machines (the very biggest parallel computers). A possible model for the very high performance part of GEM code development.
