“I’d like to propose that we routinely compare machines using the metric of data motion capacity, or their ability to move data quickly,” Snavely told attendees of the ‘Get Ready for Gordon – Summer Institute’ being held this week (August 8-11) at SDSC to familiarize potential users with the unique capabilities of SDSC’s new Gordon data-intensive supercomputer.
Gordon, the result of a five-year, $20 million award from the National Science Foundation (NSF), is the first high-performance supercomputer to use large amounts of flash-based SSD (solid state drive) memory. With about 300 trillion bytes of flash memory and 64 I/O nodes, Gordon will be capable of handling massive data bases while providing up to 100 times faster speeds when compared to hard drive disk systems for some queries. Flash memory is more common in smaller devices such as mobile phones and laptop computers, but unique for supercomputers, which generally use slower spinning disk technology.
The system is set to formally enter production on January 1, 2012, although pre-production allocations on some parts of the cluster will start as early as this month for U.S. academic researchers.
“This may be a somewhat heretical notion, but at SDSC we want a supercomputer to be data capable, not just FLOP/S capable,” said Snavely, whom along with many other HPC experts now contend that supercomputers should also be measured by their overall ability to help researchers solve real-world science problems. Snavely’s proposal includes a measurement that weights DRAM, flash memory, and disk capacity according to access time in a compute cycle.A common term within the supercomputing community, peak speed means the fastest speed at which a supercomputer can calculate. It is typically measured in FLOP/S, which stands for FLoating point OPerations per Second. In lay terms, it basically means peak calculations per second. In June, a Japanese supercomputer capable of performing more than 8 quadrillion calculations per second (petaflop/s) was ranked the top system in the world, putting Japan back in the top spot for the first time since 2004, according the latest edition of the TOP500 List of the world’s supercomputers. The system, called the K Computer, is at the RIKEN Advanced Institute for Computational Science (AICS) in Kobe, Japan, and replaced China's Tianhe-1A system as the fastest supercomputer in the rankings, which has been using this metric since 1993.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
