by Mahesh Kukreja on May 4, 2011

The Indian Space Research Organization (ISRO) has successfully built India’s fastest Supercomputer with a peak performance of 220 trillion operations per second. The performance is measured in terms of floating point operations per second (FLOPS).

SAGA-220 stands for Supercomputer for Aerospace with GPU Architecture-220 TeraFLOPS. It is developed for solving complex aerospace problems.

The supercomputer is designed using commercially available hardware and open-source software components. The system is built up of 400 NVIDIA Tesla 2070 graphic processing units (GPUs) and an equal number of Intel Quad Core Xeon central processing units (CPUs). The hardware has been provided by Wipro.

Each GPU & CPU provides performance of 500 GigaFLOPS and 50 GigaFLOPS respectively. The total performance if upto 220 TeraFLOPS. The GPUs provide a significant advantage over the conventional CPU-based system in terms of cost, power, and space requirements.

The system consumes power of only 150 KW. Hence it is environmentally green. This system can also be easily scaled to many PetaFLOPS (1000 TeraFLOPS).

The supercomputer costs about Rs. 14 crore or US $3150000.

Apple claims Safari 4 to be the Fastest Browser

by Mahesh Kukreja on June 18, 2009

Safari 4 is World’s fastest browser: Apple

When compared to other browsers, Apple boasts that Safari 4’s JavaScript is up to eight times faster than IE 8 and more than four times faster than Firefox 3; and Safari 4 loads HTML web pages more than three times faster than IE 8 and three times faster than Firefox 3.

Safari 4 includes HTML 5 support for offline technologies and support for advanced CSS Effects. Apple at the WWDC was also proud to point out that Safari 4 is the first browser to pass the Web Standards Project’s Acid3 test.

Safari is built off of WebKit, which is the open source browser engine that’s also used by popular mobile browsers and even Google’s Chrome. It’s interesting that Apple chose to compare Safari 4 against IE8 and Firefox 3, but left out comparisons with Chrome 2.

Both PC and Mac users can download Safari 4 here.
