FASTRA II Puts 13 GPUs In a Desktop Supercomputer
An anonymous reader writes "Last year tomography researchers of the ASTRA group at the University of Antwerp developed a desktop supercomputer with four NVIDIA GeForce 9800 GX2 graphics cards. The performance of the FASTRA GPGPU system was amazing; it was slightly faster than the university's 512-core supercomputer and cost less than 4000EUR. Today the researchers announce FASTRA II, a new 6000EUR GPGPU computing beast with six dual-GPU NVIDIA GeForce GTX 295 graphics cards and one GeForce GTX 275. The development of the new system was more complicated and there are still some stability issues, but tests reveal the 13 GPUs deliver 3.75x more performance than the old system. For the tomography reconstruction calculations these researchers need to do, the compact FASTRA II is four times faster than the university's supercomputer cluster, while being roughly 300 times more energy efficient." -
Supercomputer Built With 8 GPUs
FnH writes "Researchers at the University of Antwerp in Belgium have created a new supercomputer with standard gaming hardware. The system uses four NVIDIA GeForce 9800 GX2 graphics cards, costs less than €4,000 to build, and delivers roughly the same performance as a supercomputer cluster consisting of hundreds of PCs. This new system is used by the ASTRA research group, part of the Vision Lab of the University of Antwerp, to develop new computational methods for tomography. The guys explain the eight NVIDIA GPUs deliver the same performance for their work as more than 300 Intel Core 2 Duo 2.4GHz processors. On a normal desktop PC their tomography tasks would take several weeks but on this NVIDIA-based supercomputer it only takes a couple of hours. The NVIDIA graphics cards do the job very efficiently and consume a lot less power than a supercomputer cluster." -
Futuremark And Gainward Tangle Over Benchmarks
An anonymous reader writes "The optimization troubles in GPU land aren't over yet. Yesterday Futuremark released a new anti-optimization patch for 3DMark03. Gainward (who sell graphics cards using NVIDIA hardware) today made a comment that Futuremark had disabled certain features in their ForceWare 52.16 drivers, thus resulting in huge performance drops. A few hours ago Futuremark made an official statement about this : 'The accusation is totally wrong because what it suggests is not even feasible technically. 3DMark03 does not talk to graphics driver, it talks to the DirectX API, which then talks to the driver. Thus, it is impossible for the application to disable GPU compiler...'" -
Memory Activity LEDs
Azert writes "Since a few months almost every popular memory maker includes heatspreaders with their fastest memory modules. Probably Corsair is setting a new fashion with their new line of memory with memory activity LEDs XMS ProSeries modules feature a row of LED's on the top edge that display real-time memory activity level. Each memory bank has a row of nine dedicated activity LED's that alight as the level of memory activity increases. 512 Mbyte XMS ProSeries modules, with two banks, have a total of 18 activity LED's in green, yellow and red." -
