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. The interface card also implements Remote Direct Memory Access (RDMA) which allows the cards to place data directly into the memory of the end node so that no Kernel intervention is required. When …

HPC Re-Engineering
