Performance evaluation of a parallel I/O architecture

[[abstract]]Presents the results of a study conducted to evaluate the performance of parallel I/O on a massively parallel processor (MPP). The network traversal and total processing times are calculated for I/O reads and writes while varying the I/O and non-I/O request rates and the request size. Also studied are the performance impacts of I/O and non-I/O traffic on each other. The results show that the system is scalable for the I/O loads considered; however, the scalability is limited by I/O node saturation or by considerable network contention[[fileno]]2030118030015[[department]]電機工程學
