The Physics of the Parallel Machines
I argue that architectures for massively parallel computers must be designed to go beyond supporting a particular class of algorithms to supporting the underlying physical processes being modelled. I shall discuss specifically physical processes modelled by partial differential equations (PDEs) and argue that an efficient architecture must go beyond nearest neighbor mesh interconnections and support global and hierarchical communications.
