| Abstract: | The weak performance of communication subsystem is one of the key issues that prevent software distributed shared memory systems(DSMs) from showing high performance. User level networking (ULN) can fully take advantage of the high performance of network hardware. ULN can reduce memory copies and software overhead so that the performance of both bandwidth and latency will be improved. Discussed in this paper is the work on designing and implementing a high performance user level communication substrate for a software DSM that can improve the performance of both communication and computation. So the performance of the software DSM is improved significantly. |
