with "multi-grid clustering" I meant joining multiple grids with one logical machine, basically what you're trying to achieve for december; MPP = Massively Parallel Processing, a shared memory machine, which is a cluster but not in the sense that several individual hosts work on a problem but are otherwise a system in their own right (i.e., MPP machines are always SSI and share one virtual memory map). IRIX on a cluster of Origins is MPP and SSI for example, but an application using MPI to run on multiple nodes isn't.
