The system, called Kraken, will have an expected performance of about 20 trillion calculations per second, or 20 teraflops. It's one of two machines the Naval Oceanographic Office is buying in a deal IBM said is worth tens of millions of dollars.
The flagship system is a cluster of 386 eight-processor p655 machines, which use IBM's Power4+ processor and its AIX version of Unix, according to IBM.

The Navy office is an established supercomputer customer. In 2001, itfor the task, and in 2002, added an .
IBM is several years into a campaign to topple Hewlett-Packard, the No. 1 company in the high-performance computing market. Big Blue has had some success,on the Top500 list of the fastest supercomputers this June.
