A reliability analysis based scheduling algorithm in heterogeneous system

概要

In heterogeneous systems, if under active replication schema, tolerating t failures often needs t+1 processors. However, using so many replicas for one task is wasting resources, especially when the reliability of processors is high. In this paper, we propose a new scheduling algorithm based on the reliability analysis of each processor. For each task in a workflow, a dynamic number of replicas will be scheduled simultaneously. The experiments show that our scheduling algorithm uses much less resources than original active replication schema.
