Workflow overhead analysis and optimizations

  title={Workflow overhead analysis and optimizations},
  author={Weiwei Chen and Ewa Deelman},
The execution of scientific workflows often suffers from a variety of overheads in distributed environments. It is essential to identify the different overheads and to evaluate how optimization methods help reduce overheads and improve runtime performance. In this paper, we present an overhead analysis for a set of workflow runs on cloud and grid platforms. We present the overhead distributions and conclude that they satisfy an exponential or uniform distribution. We compare three methods to… CONTINUE READING
