Enabling Production-Level Computing on Linux and Windows Ethernet and Infiniband Clusters with MPI / Pro and ClusterController

This paper reviews key requirements for production-level cluster computing and how these requirements impact the architecture of message-passing middleware and resource managers used on clusters. In addition to providing high performance and scalability of target applications, system requirements include correctness, strong compliance with standards (both community and industry), robustness (stable operation under heavy and long-term loads), predictability, sufficient security, and efficient use of system resources. This paper distinguishes between research projects in the area of cluster computing, which typically address clusters from a scientific and research point of view, and commercial-grade solutions whose design and architecture are specifically aimed at meeting the requirements of production computing. MPI/Pro and ClusterController are presented here as examples of interoperable commercial-grade solutions that jointly address these issues. Perspectives on the current and future uses of clusters for parallel processing are given, and comparison of user experiences with commercial and freeware are mentioned.
