IBM again tops supercomputer rankings

ASCI White, IBM's classified supercomputer used for nuclear weapons research at the Lawrence Livermore National Laboratory in California, was ruled the world's most powerful, followed by the company's machine at the National Energy Research Scientific Computing Center (NERSC), also in California.

The TOP500 list, published every six months by researchers from University of Tennessee and the University of Mannheim, was made public at the Supercomputing 2001 Conference, under way this week in Heidelberg, Germany. Researchers measure supercomputers' speed and power using a benchmarking standard called the Linpack test.

IBM also dominated the previous list, released in November, with ASCI White taking first place, and Big Blue machines in five of the top 10 positions.

Third place went to Intel's ASCI Red, at Sandia National Laboratories in New Mexico; IBM took fourth for its ASCI Blue-Pacific machine, also at Lawrence Livermore; and fifth-place honors went to Hitachi Ltd. for its SR8000/MPP, at the University of Tokyo.

IBM officially announced delivery the NERSC machine, capable of a theoretical peak of 3.8 trillion calculations per second, in a statement Thursday. The supercomputer will be used for research projects including simulating internal-engine combustion in a bid to develop more fuel-efficient and less polluting vehicles.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
