Research on the Parcels Communication Mechanism of High Performance Parallel PIM Systems
Parallel systems based on PIM technology are expected to provide higher scalability, adaptability, robustness, fault tolerance and lower power consumption than current MPPs or commodity clusters. By Parcels, PIM parallel systems can easily implement message-driven computation, overlap computation and communication, reduce latency effects on performance of fine-grained parallelism applications and take advantage of the tremendous amount of internal bandwidth available on a PIM node and the locality exhibited by the application. This paper lays stress on the introduction of the parcels communication mechanism and the parcels communication model, and explores typical systems that using parcels. Finally we analyze existing problems about parcels and point the further research directions.
