| The Preliminary Evaluation of MBP-light with Two Protocol Policies for A Massively Parallel Processor -- JUMP-1 -- (2007) | |||||||||||||||
Abstract | |||||||||||||||
| A massively parallel processor called JUMP-1 has been developed to build an efficient cache coherent-distributed shared memory (DSM) on a large system with more than 1000 processors. Here, the dedicated processor called MBP (Memory Based Processor) -light to manage the DSM of JUMP-1 is introduced, and its preliminary performance with two protocol policies --update/invalidate-- is evaluated. From results of its simulation, it appears that simple operations like the tag check and the collection/generation of acknowledgment packets are mostly processed by the hardware mechanisms in MBP-light without aids of the core processor with both policies. Also, the buffer-register architecture adopted by the core processor in MBP-light is exploited enough to process a protocol transaction for both policies. 1. Introduction A Cache Coherent Non-Uniform Memory Access machine (CC-NUMA) is one of hopeful candidates for future common high performance machines. Unlike busconnected multiprocessors, the s... | |||||||||||||||
