Enhancing the Performance of Tiled Loop Execution onto Clusters Using Memory Mapped Network Interfaces and Pipelined Schedules

摘要

This paper describes the performance benefits attained using enhanced network interfaces to achieve low latency communication. Our experimental testbed concerns the parallel execution of tiled nested loops onto a Linux PC cluster with PCI-SCI NICs (Dolphin D330). Tiles are nec- essarily exchanging data and should also have large com- putational grain, so that their parallel execution becomes beneficial. We schedule
