Hitachi SR8000 F1 at LRZ operational - over 1 Tflop/s of raw LinPack performance

Munich 28 Apr 00 Hitachi has successfully installed the Hitachi SR8000 F1 at the Leibniz Rechnenzentrum in Munich Germany. Currently the machine is undergoing its final stability test during 30 days of operation. In a trhoughput benchmark, the machine showed a sustained performance of 424 Gflop/s. LRZ expects that in the next TOP500 list that will be published in June at the Mannheim Supercomputer Conference, the machine will end close to the top 3, after the big US national centres.

A supercomputer like the Hitachi is not a "plug an play" type of machine. It needs its own powersupply, because it works on Japanese 200V current. A seperate 800KVA-Transformator was installed for this.

Seven cool units, each with a capacity of 70 KW are needed to keep the system from overheating.

The machine was benchmarked with two programmes. One is the well-know LinPack, with 120.000 unknows, that is also used as the basis for the TOP500. With this, the machine reached just over 1 Tflop/s. This will bring the machine in the upper region of even the TOP500. The second, more realistic benchmark was a chemical code that reached a 424 Gflop/s sustained performance. Just a little below 50% of the raw LinPack performance.

The Hitachi is the supercomoputer for the whole country of Bavaria. To support it, ant to provide access to researchers all over the country, a knowledge network called KONWIHR (Kompetenznetzwerk für Technisch-Wissenschaftliches Hoch- und Höchstleistungsrechnen in Bayern) has been formed. It is part of the High-Tech-Offensive of the Bayerischen Staatsregierung.
