IBM claimed bragging rights Wednesday as its Roadrunner supercomputer earned the title of the world's most powerful supercomputer. The ranking, bestowed during the International Supercomputing Conference in Dresden, Germany, is a biannual event that ranks the 500 most powerful computers around the world. The Roadrunner, located at the U.S. Department of Energy's Los Alamos National Laboratory, achieved a peak performance of 1.026 petaFLOPS to take the top spot.

So old-school uncool, the mainframe computer -- the workhorse of the IT world running the majority of today's global business transactions, the mission-critical platform of choice for virtually every member of the Global 2000 as well as local, state and federal governments -- is said to be going the way of other '60s artifacts like the vinyl LP. Distributed client/server computing looks to be replacing the mainframe as the core of business. Companies are migrating workloads off their mainframes because mainframe technologies have percolated down to distributed systems.

IBM's Blue Gene/L System once again ranks as the fastest computer in the world, coming in at first place on the TOP500 Supercomputer Sites, an organization that ranks the world's most powerful systems. The results were announced Monday at the SC07 Conference, held in Reno, Nev. Located at the Lawrence Livermore National Laboratory, a Department of Energy lab in Livermore, Calif., the system performs 478.2 teraflops -- 478.2 trillion calculations per second. Blue Gene has come in first in the semiannual ranking since November 2004.

Masaya Igarashi wants $200 headphones for his new iPod Touch, and he's torn between Nintendo's Wii and Sony's PlayStation 3 game consoles. When he has saved up again, he plans to splurge on a digital camera or flat-screen TV. There's one conspicuous omission from the college student's shopping list: a new computer. The PC's role in Japanese homes is diminishing, as its once-awesome monopoly on processing power is encroached by gadgets such as smart phones that act like pocket-size computers.
