Cambridge University has deployed an InfiniBand networking system to support its bid data supercomputer.

The university is using Mellanox Technologies' FDR InfiniBand system to support its supercomputer, ranked 166th in the world's top 500 list of supercomputers based on throughput, and number two in the world by energy efficiency.

The supercomputer drives the SKA computing system development within the SKA Open Architecture LAB. The SKA is a multinational collaboration which is building the world’s largest radio telescope.

“The network design was specifically architected to provide the highest I/O bandwidth possible for large scale big data challenges," said Paul Calleja, director of high performance computing at the University of Cambridge.

“We chose Mellanox’s end-to-end FDR InfiniBand interconnects to connect the system, specifically by using their Connect-IB adapters in a dual rail network, as well as utilising GPUDirect RDMA communication acceleration to significantly increase the system's parallel efficiency.”
