Processor mapping techniques toward efficient data redistribution
IEEE Transactions on Parallel and Distributed Systems(1995)
摘要
Run-time data redistribution can enhance algorithm performance in distributed-memory machines. Explicit redistribution of data can be performed between algorithm phases when a different data decomposition is expected to deliver increased performance for a subsequent phase of computation. Redistribution, however, represents increased program overhead as algorithm computation is discontinued while d...
