The list is based on a semi-annual survey run by the TOP500 Project, which is sponsored by the German University of Mannheim, the Innovative Computing Laboratory at the University of Tennessee in Knoxville, and the National Energy Research Scientific Computing Center at the National Energy Research Scientific Computing Center in Berkeley, Calif.
IBMs Blue Gene/L DD1 came in at No. 4, and the Blue Gene/L DD2, grabbed the No. 8 spot. The DD1 system uses over 8,000 PowerPC 440 processors and takes up about as much space as four refrigerators, considerably smaller than other supercomputers. It has a peak speed of 16 teraflops and a sustained speed of 11.68 teraflops.
In the November list, an earlier version of the Blue Gene system ranked 73rd. And the current system is operating at less than one fifteenth of its planned capacity, according to a statement by IBM.
A Blue Gene model will likely displace the Earth Simulator as the top supercomputer a year from now, perhaps sooner, predicted the compilers of the list.
The Blue Gene project was first designed to model protein folding, or the process by which proteins achieve their intricate, three-dimensional shapes, an in-silico task that has long been a holy grail of academics and the drug industry.
Already, a Blue Gene system is being used to study how a particularly important class of proteins fold, important information for asthma, cancer and inflammation research, as well as for cardiovascular and mental health diseases.
However, IBM believes Blue Gene has potential beyond the tough task it was designed for. The company will aim the system at applications such as online search engines, geologic simulations, financial market modeling and risk analysis.
For the first time, less-expensive cluster computers were the most common architecture in the TOP500 list. Over half, or 287, of the systems run processors from Intel Corp.
