"Wow, that's some news this week at SuperComputing 08. Apparently Microsoft Windows HPC Server 2008, with a Chinese hardware OEM (Dawning), made #10 on the Top500 list, edging out #11 by only 600 Gflops. Folks were shocked to see Microsoft getting so serious around HPC; I think we are only beginning to see a glimpse of Microsoft in the HPC field.

In recent months, the concept of 'cloud computing' was all the buzz. European researchers think about another name, the World Wide Grid, which could run on top of the Internet. In an article to appear soon, ICT Results will report about the g-Eclipse project. As the scientists said, 'the g-Eclipse project aims to build an integrated workbench framework to access the power of existing Grid infrastructures. The framework will be built on top of the reliable eco-system of the Eclipse community to enable a sustainable development.' The project started in July 2006 and was successfully completed in June 2008 for a total cost of 2.5 million including a EU contribution of 1.96 million.

IT-Online - HP tops supercomputer list Wednesday, 19 November 2008, 11:38

HP's BladeSystem c-Class server has been named as the world's largest supercomputer. This is the second year in a row that HP has topped the list of the 500 most powerful computers in the world.

HP computers make up 41,8% of the list, with IBM computers making up 37,6%.

AMD has clawed back some market interest in the server area.

IEEE Spectrum: The African Hacker By G. Pascal Zachary

With home-brewed code and a little help from Microsoft, a programmer in Ghana launches Africa's first software empire

The first time I meet Hermann Chinery-Hesse, he is pouring diesel fuel from a plastic jug into an electric generator. I am in the West African country of Ghana, visiting his software company, Soft Tribe Ltd.

Chinery-Hesse is chief of the Tribe. He's made a small fortune writing software, working as a systems architect, and selling computer code to hundreds of businesses in his country of 21 million people. He drives a Mercedes. He wears imported Birkenstock sandals. He hails from a prominent family, was born in Dublin, and went to college in the United States. He could be working anywhere on the strength of his Irish passport, yet he's spent the past dozen years in Accra, Ghana's coastal capital and one-time slave-trade hub.

This steamy December morning, with deadlines looming, his electricity is out, his programmers are idle, and he's feeding fuel to a balky 50-kilovolt-ampere generator—one of the three he keeps at the ready.

Having emptied his container and thus delivered power to his 18 programmers—about one-tenth of all full-time code writers in Ghana—Chinery-Hesse relaxes and, for the first time, acknowledges my presence. Stroking his beard, he quips, "If we Africans are to develop, we must want to get our hands dirty."

IEEE Spectrum: Multicore Is Bad News For Supercomputers (First Published November 2008) By Samuel K. Moore

Adding cores slows data-intensive applications

Trouble Ahead: More cores per chip will slow some programs [red] unless there’s a big boost in memory bandwidth [yellow].

With no other way to improve the performance of processors further, chip makers have staked their future on putting more and more processor cores on the same chip. Engineers at Sandia National Laboratories, in New Mexico, have simulated future high-performance computers containing the 8-core, 16‑core, and 32-core microprocessors that chip makers say are the future of the industry. The results are distressing. Because of limited memory bandwidth and memory-management schemes that are poorly suited to supercomputers, the performance of these machines would level off or even decline with more cores. The performance is especially bad for informatics applications—data-intensive programs that are increasingly crucial to the labs’ national security function.

AMD is still widely used at the top end of the HPC spectrum often due to interconnect performance.

Pumping out a sustained 1.64 quadrillion mathematical calculations per second (1.64 petaflops) after a recent technological overhaul, the Cray XT Jaguar is now the world's latest fastest supercomputer (huge disclaimer coming) for non-classified research. And once you see what's under the hood, you'll know why.

In a conventional data centre, 35% to as much as 50% of the electrical energy consumed is for cooling versus 15% in best-practice "green" data centres.

"Virtually all data centres waste enormous amounts of electricity using inefficient cooling designs and systems," says Paul McGuckin, research vice-president at Gartner. "Even in a small data centre, this wasted electricity amounts to more than 1 million kilowatt hours annually that could be saved with the implementation of some best practices."
The overriding reason for the waste in conventional data centre cooling is the unconstrained mixing of cold supply air with hot exhaust air.

The Council for Scientific & Industrial Research (CSIR) is managing to stay relevant, and provides a significant component of South Africa's research and development (R&D).

As science and research outcomes continue to improve South Africa's competitiveness and service delivery, the CSIR believes that it remains a key player in the country's national system of innovation (NSI).

These are bold claims to make, but stand in stark contrast to SA's rankings in the competitiveness indexes, our crumbling education systems, the arbitrary S&T projects that still produce no tangible results and my exeprience with various departments.

Purdue University has started with a (slightly frustrating) tool to educate young people about clustering and cluster spending resource allocation.

Supercomputing: The Video Game
By Ashlee Vance

In the vast field of technology, supercomputing stands as one of the least accessible disciplines. It’s an area where borderline wizardry occurs — people harness the power of thousands of machines to simulate nuclear explosions, predict the weather or model chemical reactions.
