High-performance systems are undergoing a major shift as commodity multi-core systems become increasingly prevalent. As the number of processes per compute node increase, the other parts of the system must also scale appropriately to maintain a balanced system. In the area of high-performance computing, one very important element of the overall system is the network interconnect that connects compute nodes in the system. InfiniBand is a popular interconnect for high-performance clusters. Unfortunately, due to limited bandwidth of the PCI-Express fabric, InfiniBand performance has remained limited.
