Telstra has revealed the addition of almost one million new mobile services in the six months to December 2011, but Sensis revenues plummeted 24 percent in 12 months.
Computing giant IBM plans to build the most powerful supercomputer to date using a combination of AMD Opteron processors and Sony's new Cell chip to be used in PlayStation 3 games consoles.
The new supercomputer, codenamed Roadrunner, is expected to be able to
execute at four times the speed of the no.1 supercomputer listed in the
Top 500, the IBM BlueGene/L at the Lawrence Livermore National
Laboratory, which has been clocked at more than 280 teraflops (280
trillion floating point operations per second).
If it achieves its expected performance, Roadrunner will be the first
computer in history to enter the petaflop (quadrillion operations per
second) class.
IBM is crediting the performance boost of Roadrunner to the new Cell
chip, of which there will be more than 16,000 running alongside 16000
Opteron processors.
The new supercomputer will be housed at Department of Energy's Los
Alamos National Laboratory and used in simulations concerning the aging
of nuclear materials.
The power of the eight processor cell chip, which was jointly designed
by IBM, Toshiba and Sony, has been recognized by researchers as a
potential aid in solving high performance computing applications.
Last month a project started by US biological scientists, called
folding@home, announced its intention to enlist at least 10,000 PS3
consoles owned by gamers in a network to achieve supercomputing
performance in determining how protein performance can cause diseases
such as Alzheimer's and Cancer.
According to the researchers a network of 10,000 PS3 consoles can also
achieve petaflop performance and they eventually want to be the network
to 100,000 consoles or more.
