Concurrent transcontinental Supercomputing: Infinicortex

We have successfully demonstrated 100Gbps trans-Pacific connectivity, with InfiniBand transport layer, connecting Asia, Australia and North America; four countries: Singapore, Australia, Japan and the USA; seven Universities and two large research organisations: Agency for Science, Technology and Research (A*STAR) Singapore and Oak Ridge National Laboratory (ORNL) USA. The demonstration took place at the Supercomputing 2014 conference in New Orleans Four separately important and interesting concepts were integrated for the first time together to realise the InfiniCortex: 1) High bandwidth 100Gbps intercontinental connectivity linking Asia and the USA; 2) InfiniBand technology over trans-continental distances using Obsidian Strategics range extenders including BGFC-based subnet routing. 3) Connecting separate InfiniBand sub-nets with different network topologies to create a single computational resource: Galaxy of Supercomputers. 4) Running workflows and RDMA applications on such a distributed computational infrastructure, especially using ADIOS I/O framework.
