Stanford seizes 1 million processing cores to study supersonic noise
In short order, the Sequoia supercomputer and its 1.57 million processing cores will transition to a life of top-secret analysis at the National Nuclear Security Administration, but until that day comes, researchers are currently working to ensure its seamless operation. Most recently, a team from Stanford took the helm of Sequoia to run computational fluid dynamics simulations -- a process that requires a finely tuned balance of computation, memory and communication components -- in order to better understand engine noise from supersonic jets. As an encouraging sign, the team was able to successfully push the CFD simulation beyond 1 million cores, which is a first of its kind and bodes very well for the scalability of the system. This and other tests are currently being performed on Sequoia as part of its "shakeout" period, which allows its caretakers to better understand the capabilities of the IBM BlueGene/Q computer. Should all go well, Sequoia is scheduled to begin a life of government work in March. In the meantime, you'll find a couple views of the setup after the break.
Livermorium and Flerovium take a seat at the Periodic Table
Just when we thought those pesky scientists had stopped messing with the Periodic Table, the International Union of Pure and Applied Chemistry goes and ratifies another two. The pair of elements were discovered in partnership between the Flerov Laboratory of Nuclear Reactions, Joint Institute for Nuclear Research in Russia and the Lawrence Livermore National Laboratory in the States. Element 114 has taken on the spell-check-worrying nomenclature Flerovium (Fl), while 116 becomes Livermorium (Lv). Eagle-eyed readers will notice that both take a name from the labs where they were discovered, the former named after Georgiy N. Flerov and the latter after Ernest O. Lawrence -- both atomic pioneers in their respective countries. The official names will get their first official publication in July's edition of Pure and Applied Chemistry. We guess those textbook makers will be rubbing their hands in glee at all those revised editions it'll sell next term. [Image courtesy of the BBC / Talkback Thames]
World's largest laser opens for business in California
Another day, another laser... well, not so fast. This particular laser just so happens to officially carry the "world's largest title." Built at Lawrence Livermore National Laboratory in Livermore, California, and housed in the National Ignition Facility -- or NIF -- it was completed at the end of March, and has just now been officially dedicated and opened for business. The laser inside the three-football field-sized building will aim to create a "star" on earth by focusing 192 beams at a pea-sized target, generating temperatures over 100 million degrees and pressure over 100 billion times the earth's atmosphere. The process will create nuclear fusion -- the reaction that powers the sun and the stars. it sounds pretty complicated, and we'd hate to be in town if something goes awry, but we're crossing our fingers for the team! Hit the read link for much, much more information about the project.[Via Physorg]
IBM's BlueGene/L: world's fastest supercomputer, 3 years running
The TOP500 supercomputing list was just announced and IBM's BlueGene/L system has kept its crown. In fact, IBM's and the Department of Energy's co-developed monster at Lawrence Livermore has occupied the number 1 position since 2004. Of course, an upgrade was required boost the Linpack benchmark to 478.2 TFlop/s from the 280.6TFlop/s the machine was clocking just 6 months ago. The top 10 swath is dominated by the US, Sweden, and Germany with India breaking into the list for the first time at the number 4 position with its HP Cluster Platform 3000 BL460c system measuring 102.8TFlop/s.
