CNETAnalysis: Behind every world’s fastest supercomputer is a high-performance visual processor, and in the case of the new Titan supercomputer, that GPU is the Nvidia Tesla K20X. Nvidia’s newly unveiled graphics accelerator is part of the company’s K20 line, which not only boasts the highest performance, but also manages to be the most energy efficient. With Titan packing 18,688 Tesla K20X GPU accelerators, the newly crowned supercomputer has a performance record of 17.59 petaflops, or 17.59 quadrillion calculations per second. “We are taking advantage of Nvidia GPU architectures to significantly accelerate simulations,” said Dr. Thomas Schulthess in a press release. According to this professor of computational physics at ETH Zurich and director of the Swiss National Supercomputing Center, such simulations will benefit fields of climate and meteorology, seismology, astrophysics, fluid mechanics, materials science, and molecular biophysics. All in the K20 family The K20X, the flagship of Nvidia’s Tesla line, surpasses all other processors with 3.95 teraflops single-precision and 1.31 teraflops double-precision peak floating point performance. Nvidia also unveiled the Tesla K20 accelerator, which delivers a strong performance of 3.52 teraflops of single-precision and 1.17 teraflops of double-precision at peak. Both the K20X and K20 are based on Nvidia’s Kepler compute architecture and have enabled more than 30 petaflops of performance delivered in the last 30 days. According to Nvidia, this is equivalent to the computational performance of last year’s 10 fastest supercomputers combined. The fastest, most efficient GPU for now The Titan supercomputer, with the help of the Nvidia K20X, took the top spot on Top500′s biannual list of the world’s top supercomputers this week. However, with the way tech specs advance, the Titan can be quickly knocked out of contention in ! six months. It replaces the new No. 2, the IBM Sequoia, which itself replaced new No. 3, the Fujitsu’s K computer. In addition to appearing at the Oak Ridge National Laboratory in Oak Ridge, Tenn., where the Titan supercomputer is located, K20 GPUs are going out to labs and universities worldwide. Early customers in the U.S. include Clemson University, Indiana University, Thomas Jefferson National Accelerator Facility, National Center for Supercomputing Applications, National Oceanic and Atmospheric Administration, Oak Ridge National Laboratory, and USC. International locations King Abdullah University of Science and Technology and Shanghai Jiao Tong University are also destined to be part of the exclusive K20 GPU club.
CNews Karachi. July 05: A Pakistani Scientist in Britain has invented a new chemical for processing plastic (polythene) bags which has the quality of dissolution after its use in 105 days.A manufacturing unit for these plastic bags was being set up in Turkey while interest has been shown in the setting up of a big unit and manufacturing firm’s head quarter in Karachi which will be used to supply such dissolvable polythene bags to Asian countries. The Director of UK based firm Bio Plast Biodegradable Plastics GL Punn while leading a 15 member delegation called on EDO Municipal Services City Government Masood Alam. The Executive Director of Bio Plast Pakistan Muhammad Hanif Awan and M. Sultan Mehmood Awan was also present on this occasion. The Director of Bio Plast informed the EDO Municipal Services about the characteristics of new chemical. He said that the firm was going to set up its first plant in Turkey which will be operative in next two months. The delegation also praised the vi
