Tech giants IBM and Sun Microsystems, have announced petaflop supercomputers, equal to one billion megaflops. They indicated there is no barrier to more computer power, but the problem is how to manage and reduce the power usage and also to improve software. The Sun system will cost about $59 million, while the IBM supercomputer runs between $1.3 million and $1.7 million for each server in the system cluster.
To build a supercomputer, the dominant cost of the systems is memory, DRAM, which a typical supercomputer will require millions of DRAM chips. DRAM drops in price like crazy--the average selling price of DRAM dropped 35 percent from December to April. But millions of chips are millions of chips. The cables aren't cheap either. In fact, they cost more than the silicon inside switching systems.
And in Asia, China is building three petaflop supercomputer by 2010 and Japan is building a 10 petaflop machine by 2011.
