Summary:
Scientific computation today is facing many scalability challenges and issues in trying to take advantage of the latest generation compute, network and graphics hardware. We present a comprehensive approach to solving four important scalability challenges: programming productivity, scalability to a large number of processors, I/O bandwidth, and interactive visualization of large data. We describe a scenario of our proposed system applied to the field of numerical relativity, in particular the simulation of a binary black hole system. Here a solver for the governing Einstein equations is generated, executed on a large computational cluster, and its output is distributed onto a temporary distributed data server using a high-speed optical grid, and finally visualized remotely using distributed visualization methods and optical networks. This system is applicable to a large number of problems. A demonstration of this system was awarded first place in the IEEE SCALE 2009 Challenge in Shanghai, China in May 2009.
