Abstract

While for single processor and SMP machines, memory is the allocatable quantity, for machines made up of large amounts of parallel computing units, each with its own local memory, the allocatable quantity is a single computing unit. Where virtual address management is used to keep memory coherent and allow allocation of more than physical memory is actually available, virtual communication channel references can be used to make computing units stay connected across allocation and swapping.
