IBM Supercomputer Shatters Own Speed Record
An IBM Blue Gene supercomputer has nearly doubled its previous world-beating speed, performing at 135.3 trillion floating points per second, said the Department of Energy (DoE).
Source: Internet NewsThe DoE's National Nuclear Security Administration (NNSA), which uses the machine to help maintain the U.S. nuclear weapons stockpile, said the new speed trounced the supercomputer's previous speed of 70.7 teraflops.
When it is finished this summer, BlueGene/L will have 65,000 nodes for a total of 131,072 processors, said Don Johnston, a spokesman for Lawrence Livermore National Laboratory in California, which is where the system is being tested.
The previous fastest speed of 70.7 was championed by NNSA last November with the release of the latest Linpack computing benchmark.
At 70.7 teraflops last fall, scientists at Lawrence Livermore were able to perform molecular dynamics simulations of 16 million atoms with the greatest accuracy ever recorded. BlueGene/L also helped scientists studying the effects of voids in metal failure to perform such simulations with more than 2.1 billion atoms.
