N2 - The arrival multi-core processors or chip multiprocessors (CMP) operated with symmetrical multiprocessing (SMP) has made parallel computing available to the masses. Unfortunately the scalability of the SMP paradigm is poor as the number of processor cores increases. Furthermore, current alternatives to SMP, including non-uniform memory access (NUMA), cache coherent non-uniform memory access (CC-NUMA), vector computing (VEC), and message passing (MP), provide poor performance in general purpose parallel applications and/or programming with them is difficult/tedious. According to recent investigations, an idea from the early 90's - hardware implementation of a strong model of computing, e.g. the Parallel Random Access Machine (PRAM) model, this time on a scalable on-chip distributed shared memory architecture, coupled with the explicit PRAM-driven parallel programming methodology - seem to avoid these problems and therefore opens up an avenue of possibilities in future general purpose parallel computing. In this lecture, we (1) consider shortly the challenges related to on-chip parallel computing, (2) introduce shortly the current CMP paradigms and their problems, (3) introduce the idea of shared memory parallel computing under a strong model of computing, and (4) describe our attempt to realize PRAM computation on a scalable CMP architecture, experimental recursively parallel programming language, and prototype tools for compiling and optimizing programs written with the language for the architecture. Simulation results and programming examples are given.
