Kernel sharing on reconfigurable multiprocessor systems
Philip Garcia, Katherine Compton · 2008
Because of the difficulty of increasing single-threaded processor performance, multi-core systems are becoming increasingly popular. These systems bring new challenges to the design of a reconfigurable computing system, with reconfigurable hardware potentially shared between multiple simultaneously-executing applications. In this paper, we examine how to best use reconfigurable hardware in a multiprocessor system. One of the key aspects of this work is improving overall system throughput by sharing configured circuits between multiple processes concurrently executing on the system. In this work, we show that using our extensions for sharing configured circuits between processes improves overall system throughput, and outperforms a static schedule of the kernels between the multiple processes.
