Cache coherency, clustering, and Kernel virtualization

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.
