Infiniband Fat Trees

Overview Infiniband is primarily used in High Performance Computing (HPC) and provides a very fast network interconnect with an incredibly small latency. One of the most common topologies implented is the “Fat Tree” layout. The fat tree topology has host nodes connected at the end points of the network via PCI Infiniband cards. The Infiniband …

HPC Re-Engineering

Overview We have been tasked with proposing how we would re-engineer an aging SGI High Performance Computing platform. The platform is a 35 Node cluster running Red Hat 6.7 on each node with a Lustre file system mount and a /home file system presented via NFS from a Hierarchical Storage Node (over an FDR Infiniband …
