A Physical and Virtual Compute Cluster Resource Load Balancing Approach to Data-Parallel Scientific Workflow Scheduling

To execute workflows on a compute cluster resource, workflow engines can work with cluster resource manager software to distribute jobs into compute nodes on the cluster. We discuss how to interact with traditional Oracle Grid Engine and recent Hadoop cluster resource managers using a dataflow-based scheduling approach to balance compute resource load for data-parallel workflow execution. Our experiments show that: 1) The presented approach can balance computational resource load well by interacting with the resource managers and provides good execution performance on both physical and virtual clusters, 2) Oracle Grid Engine outperforms Hadoop for CPU-intensive applications on small-scale clusters.
