Setting I/O Performance Records

One of the most well-recognized names in the world, the University of Cambridge’s mission is to “contribute to society through the pursuit of education, learning and research at the highest international levels of excellence.” The university’s Research Computing Services provides high performance computing (HPC) resources to support work conducted in its many colleges of science and across industry in the U.K. To leverage today’s data-driven world, Research Comput­ing Services deployed its latest supercomputer, a 2.27 petaFLOPS system called Cumulus.2 Built to address the I/O challenges of large data in simulation and artificial intelligence (AI), Cumulus uses a unique Data Accelerator (DAC) designed into the network topology built around Intel® Omni-Path Architecture (Intel® OPA). Cumulus’ DAC earned Cambridge the top performance rating on the latest I/O-500 list from the Virtual Institute for I/O1.
