Big Blue announced yesterday that its got its new Blue Gene/P supercomputer, to operate at a petaflop speed. Now, According to ZD Net, Sun says its new Constellation System can hit a peak of two Petaflops.
At the heart of the Sun system is a switch, code-named Magnum, which has 3,456 ports that frees up data pathways inside the computer. Sun thinks that the density of ports, and the large number of them, creates a "cascading effect in performance", which is always pretty to watch.
The Texas Advanced Computing Centre (TACC) is building a Constellation system based around AMD Barcelona chips. If it can get enough chips in time, then Sun will get itself in the next top supercomputers in the world list.
