SAN JOSE, Calif. (AP) - An IBM-built computer that has topped the list of the world's 500 most powerful supercomputers has widened its lead in the latest ranking released Monday.
The computer named Blue Gene/L, deployed at Lawrence Livermore National Laboratory, has doubled its performance to 280.6 trillion calculations per second (teraflops), up from 136.8 teraflops from the list released in June.
The system, which is used to study the U.S. nuclear stockpile and perform other research, was officially completed this summer after it was doubled in size. Researchers expect it will hold the top spot for the foreseeable future.
