Abstract

Mapping workflow applications onto parallel platforms is a challenging problem, even for simple application patterns such as pipeline graphs. Several antagonistic criteria should be optimized, such as throughput/period and latency (or a combination). Typical applications include digital image processing, where images are processed in steady-state mode. In this paper, we study the bi-criteria mapping (minimizing period and latency) of the JPEG encoding on a cluster of workstations. We present an integer linear programming formulation for this NP-hard problem, and we present an in-depth performance evaluation of several polynomial heuristics.
