Performance evaluation of a parallel I/O architecture
Sandra Johnson Baylor, Caroline Benveniste, Yarsun Hsu · 1995
Presented are the resr.dts of a study conducted to evaluate the performance of parailel 1/0 on a massiveiy parallel processor (MPP).The network traversal and total processing times are calculated for [/0 reads and wriles whiie vaying the 1/0 and non-I/O request rates and the request size.A Iso studied is the performance impact of I/O and non-I/O traffic on each other.The resuits show that the system is scalable for I/O loads considered; however, the scalability is limited by 1/0 node saturation or considerable network contention.
