NEC Strikes Back With SX-8 Supercomputer
News for nerds writes "It was just 3 weeks ago that we learned IBM's BlueGene/L with 36.01 TFlops edged out NEC's Earth Simulator, but today NEC announces a new SX-8 supercomputer with a peak processing performance of 65 TFlops (press release). It may be available in the U.S. as Cray's OEM like SX-6." -
IBM Sets Supercomputer Speed Record
T.Hobbes writes "IBM's BlueGene/L has set a new speed record at 36.01 TFlops, beating the Earth Simulator's 35.86 TFlops, according to internal IBM testing. 'This is notable because of the fixation everyone has had on the Earth Simulator,' said Dave Turek, I.B.M.'s vice president for the high-performance computing division. The AP story is here; the NY Times' story is here." -
Sun Working to Obsolete Motherboards
perl_camel_jockey writes "Sun is developing a new technology that promises to increase computing power by eliminating the need for physical, soldered chip-to-chip connections on the motherboard. Called 'proximity communications', it portends the ability for chips to talk to one another wirelessly just by being next to each other. Potential applications in computer design abound. Apparently this is part of Sun's Hero program, recipient of a $50 million grant from DARPA's High Productivity Computing Systems program to rejuvenate supercomputing in the US and regain the lead lost to Japan, in particular to NEC's Earth Simulator, ranked as the most powerful supercomputer in the world." -
Drilling Under the Sea
prof_peabody writes "The IODP (Intergrated Ocean Drilling Program) is about to get rolling in a couple of days. If you live in one of these countries then your tax dollars have contributed to the construction of the giant drillship Chikyu, which was launched a little while back (project timeline). The American contigent website is loaded with info and obligatory acronyms. The first leg of the IODP will investigate how water flows through rock formations beneath the seafloor during an eight-week expedition this summer to the eastern flank of the Juan de Fuca Ridge off the coast of British Columbia. Some of you geeks with beards may remember the DSDP (Deep Sea Drilling Project) or the recently completed ODP (Ocean Drilling Program). The real advance in the new program that will cost well over a billion dollars is the IODP riser drill ship that 'will provide a way to drill into continental margins where oil and gas deposits can cause drilling safety concerns and into regions with thick sediment sections, fault zones, and unstable formations.' A good overview of the IODP can be found here, and the necessary references to Megalodon and none other than The Core." -
Using Math To Design Cities And Supercomputers
caek writes "If you've played Sim City you've wrestled with one of the problems faced by supercomputer designers. Unfortunately there's no GameFAQs.com for the technical staff at Japan's Earth Simulator or Srinidhi Varadarajan and colleagues at Virginia Tech. True enough, they won't have to deal with rising crime or Godzilla but, as hinted at in a recent paper in Journal of Physics A, the physical layout of a massively parallel supercomputer is fundamentally the same problem as minimizing the time commuters spent stuck in traffic jams. Read the rest of my kuro5hin article for a popular explanation." -
Earth Simulator Now Predicting Hurricanes?
GeoGreg writes "The BBC is reporting that the Japanese Earth Simulator supercomputer is producing results showing that it is possible to model climate down to the level of severe weather events such as hurricanes. This computer has been discussed on Slashdot previously, and it sounds like at least some of the hype around this beastie was justified." -
Top 500 Supercomputers Ranked
Shadow Wrought writes "The Register is reporting on (alternate ZDNet article) the latest list of the top 500 supercomputers in the world. Top of the list is the Earth Simulator Center in Yokohama, Japan, with a benchmark performance of 35.86 Tflop/s. HP and IBM claim 159 and 158 of the systems respectively. I wonder how many teraflops Deep Thought could have done?" -
Nerd Vacation to the Earth Simulator
eecue writes "Earlier this year I went on vacation to japan. At the end of my trip I was lucky enough to receive a tour of the Earth Simulator, which is the world's fastest super computer. I took pictures and wrote about it." -
Inside The World's Most Advanced Computer
Junky191 writes: "Just came across an informational page for the Earth Simulator computer, which provides nice graphics of the layout of the machine and its support structure, as well as details about exactly what types of problems it solves. Fascinating for the engineering problems tackled- how would you organize a 5,120 processor system capable of 40Tflops, and of course don't forget about the 10TB of shared memory." Take note -- donour writes: "well, the new list of supercomputer rankings is up today. I have to say that the Earth Simulator is quite impressive, from both a performance and architectural standpoint." -
