Grid Enables Vector Supercomputing Environment
Tohoku University's Cyberscience Center, Osaka University's Cybermedia Center, Japan's National Institute of Informatics, and NEC Corp. recently announced the successful demonstration of one of the world's fastest vector supercomputing environments. The researchers created a single virtual system using a connection between two separately located vector supercomputers on Japan's National Research Grid Initiative (NAREGI) software.
The NAREGI middleware enables large-scale computing resources as separate research and development centers to be closely interconnected through high-speed networks. The network connections can be viewed as a single massive virtual computer capable of implementing large-scale parallel simulations, which were once difficult for even a single computer system to handle.
A new grid middleware component, the GridVM for the SX Vector Computer, was developed by enhancing the current capabilities on the NAREGI middleware, including job management, information provision, and resource allocation. The enhanced middleware component maintains high compatibility with the local job scheduler on the SX-9 computer at Osaka University, which enables the efficient use of vector computer resources even in a grid environment. The enhanced middleware also allows for the co-existence of conventional, or non-grid, tasks and grid tasks, enabling the computing center to provide cloud-computing services.
