Enabling scalability and performance in a large scale CMP environment

Hardware trends suggest that large-scale CMP architectures, with tens to hundreds of processing cores on a single piece of silicon, are iminent within the next decade. While existing CMP machines have traditionally been handled in the same way as SMPs, this magnitude of parallelism introduces several fundamental challenges at the architectural level and this, in turn, translates to novel challenges in the design of the software stack for these platforms. This paper presents the “Many Core Run Time” (McRT), a software prototype of an integrated language runtime that was designed to explore configurations of the software stack for enabling performance and scalability on large scale CMP platforms. This paper presents the architecture of McRT and discusses our experiences with the system, including experimental evaluation that lead to several interesting, non-intuitive findings, providing key insights about the structure of the system stack at this scale. A key contribution of this pa...
