The petascale supercomputer Tianhe-1A, which features hybrid multicore CPU and GPU computing, achieves an optimized balance of computation and communication capabilities through a proprietary high-bandwidth, low-latency interconnect fabric. The authors' message-passing service, based on scalable user-level communication and offloaded operations for large-scale, low-latency collective communication, has achieved a unidirectional bandwidth of 6,340 Mbytes/s.
