HPC Consortium: TSUBAME



On Monday Professor Satoshi Matsuoka updated the HPC Consortium attendees on TSUBAME, Asia's largest supercomputer center and the largest HPC system to date built with Sun technology. His talk was titled, "TSUBAME Update -- The People's Supercomputer at Tokyo Institute of Technology."

Since its installation, the TSUBAME user population has grown to 10,000 user registrations, which includes 1200 registered supercomputer-class users. The system has had a lot of media exposure in Japan, including several magazine cover articles and coverage on national television.

As part of creating the vision of a people's supercomputer that supports a wide variety of users, TSUBAME implements multiple usage models from best-effort to higher quality service which is billed per unit of use. Professor Matsuoka gave us a brief overview of some of the work they've done in this area and recommended a detailed Sun Blueprint titled Sun N1 Grid Engine Software and the Tokyo Institute of Technology Supercomputer Grid for further reading.

Usage continues to increase. One of Professor Matsuoka's deputies has been known to launch 20,000 simultaneous Gaussian jobs on TSUBAME! Not surprising then that in under 12 months over 1.3M ISV application runs have been done on the machine.

Work was done recently to improve TSUBAME's LINPACK performance number, which is how a machine's rankings in the TOP500 list is determined. TSUBAME moved from #9 to #14 on the list in spite of having submitted a new LINPACK run demonstrating an additional 1.5 TFLOPs, wich indicates just how competitive this list is. TSUBAME remains the largest supercomputer in Asia.
