Optimizing the Latency of Streaming Applications under Throughput and Reliability Constraints

International audienceIn this paper, we deal with the problem of scheduling streaming applications on unreliable heterogeneous platforms. We use the realistic one-port model with full computation/communication overlap. We deal with three optimization objectives. The first two, latency and throughput, are performance-related while the third, tolerating a given number of processor failures, is reliability-oriented. The major contribution of this paper is the design of a new scheduling algorithm to minimize latency under both throughput and reliability constraints. We provide a comprehensive set of experimental results, that fully demonstrate the usefulness of the proposed algorithm
