45INTERFERENCE-AWARE SCHEDULING INTERFERENCE-AWARE SCHEDULING

Overlapping communication with computation is a well-known technique to increase application performance. While it is commonly assumed that communication and computation can be overlapped at no cost, in reality they interfere with each other. In this paper we empirically eval-uate the interference rate of communication on computation via measurements on a single processor communicating on a heterogeneous collection of local and remote proces-sors, in both Java and C. We then present a model of inter-ference, which can be used for more effective application scheduling, as demonstrated by real-world experiments
