Building HPEC Systems for Performance and Fault Resiliency with InfiniBand
High Performance Embedded Computer (HPEC) systems are required to quickly process large amounts of data in real-time and are required to move that data throughout the system, from the sensor(s), to processing nodes, to output devices (including other HPEC systems) so that the data can be processed in real-time.
Over the years, a series of different interconnect strategies were developed to provide this required performance. Such interconnects include simple bus-based interconnect such as the VME and PCI busses, and more complex switched interconnects such as SKYchannel and RACEway. These switched interconnects have proven to be well suited for the HPEC domain because they provide high point-to-point throughput and multiple pathways between endpoints that deliver an even higher aggregate throughput.
