Performance Tools for Windows HPC Server 2008 R2
< Go Back
Eric Lantz, Program Manager with the Windows HPC Computing Team outlines some tools that can be used to optimize HPC Cluster performance. Three usage patterns are considered: Data Parallel, Message Passing (MPI), and SOA (Service-Oriented Architecture). The biggest gains can be made in Networking optimization. R2 features Network Direct, a new networking interface that runs on RDMA-capable hardware over Infiniband, 10 Gigabit Ethernet, as well as other Layer 2 architectures.
