Abstract : |
Achieving high-speed network I/O on distributedmemory systems is a hard problem because their architectures are, in general, ill-suited for communication processing. One of the problems is that messages are distributed over the private memories of the distributed-memory system. This can result in poor performance since communication includes a complex scatter/gather operation. This paper presents a strategy in which the task of creating large contiguous messages is performed on the distributed-memory system, thus minimizing the overhead on the network interface. The performance results for an implementation of this strategy for the iWarp system are presented. 1, |
