Overview:
This paper showed the impact of blocking factor on the performance of various applications run on Dell PowerEdge blade chassis. The results show a significant impact on the performance of an application that is highly communication intensive. The bandwidth intensive NAS benchmarks that have collective communication pattern show significant impact to the restraint cluster bandwidth caused by the blocking factor. For benchmarks that are both communication and computation intensive and that have a small volume of communication data across nodes or that have a communication pattern that is mainly point to point, the blocking factor may be of little importance.
