2007's first Top500 list is out leaded by BlueGene!

As I disclosed in my one later post dated Sunday, May 20, 2007 I am posting a yet another post on fastest supercomputer of the world. The list was published during at the International Supercomputing Conference (ISC ’07) in Dresden, Germany (http://www.supercomp.de) on June 27, 2007. Who else it can be other than BlueGene??

Yes, IBM BlueGene (http://top500.org/system/7747) installed at Lawrance Livermore National Laboratories, US (http://www.llnl.gov) topped on the list for the consequent forth time since its commissioning by delivering a stunning and steady 280.6 Teraflops! (Trillions of computations per second). In addition there were two other Supers which crossed the 100 Tflop mark -- the upgraded Cray XT4/XT3 at Oak Ridge National Laboratory, ranked No. 2 with a benchmark performance of 101.7 TFlops and Sandia National Laboratory’s Cray Red Storm system, which ranked third at 101.4 TFlops.

The unending π game

This unending figure has always attracted philosphers, mathematicians, scientists, engineers and programmers ever since last 4 Millenia. A few intersting links of the efforts made by them are listed as below. Any addenda to the same are always welcome.

Fedora 7 is released excluding the "Core"!!

After almost 24 months of continuous development and 6 concurrent core releases, Red Hat supported the Fedora was finally released as Fedora 7 alone excluding the core factor and combining the core and extras on May 31, 2007 (Just Yesterday!). It is considered to be the most stable version amongst its previous variants packed with varios features including various Spins, increased start-up and shut-down speed, secured wireless, support for encrypted FS, beautiful themes and many more to be found at http://fedoraproject.org/wiki/Releases/7/Features%3A?action=show.

In total F7 must be provided a few GB of space in your hard drive! (Now even live CD and a small bootable iso image is also available). So grab it now from here: http://fedoraproject.org/get-fedora.html
