Once again, the Energy Department's Lawrence Livermore National Laboratory can boast the world's most powerful supercomputer. The lab's BlueGene/L System topped the 29th biannual Top 500
list of the world's fastest computers, released earlier this week. This is the fourth time the system, developed by IBM, has led the list.
Using the Linpack benchmark software, BlueGene/L was able to calculate up to 280.6 trillion floating point operations per second (TFlops).
Energy also manages the next two computers on the list. A Cray XT4/XT3 system run by Oak Ridge National Laboratory was second at 101.7 Tflops, and the Sandia National Laboratory's Cray Red Storm system ranked third, at 101.4 TFlops.
The United States had 281 systems on the list, or a little more than 56 percent of the systems
. Universities ran many of these systems, as did state-run research centers and even a few companies such as IBM and Cray. Of the federal agencies, Energy had the lion's share of entries, although a few other agencies such as the Defense Department and the National Oceanic and Atmospheric Administration also had ranking supercomputers.
