• NVIDIA Powers Titan, Worlds Fastest Supercomputer For Open Scientific Research

Titan, the worlds fastest open-science supercomputer,⁽¹⁾ was completed this month at Oak Ridge National Laboratory in Tennessee, opening new windows of opportunity into the exploration of some of the worlds toughest scientific challenges.

Titans peak performance is more than 20 petaflops -- or 20 million billion floating-point operations per second -- about 90 percent of which comes from 18,688 NVIDIA® Tesla® K20 GPU accelerators. These are based on the NVIDIA Kepler™ architecture, the fastest, most efficient, highest-performance computing architecture ever built.

Researchers use ever faster supercomputers to accelerate the pace of discovery and innovation across a range of scientific fields of inquiry -- from developing more efficient engines and higher capacity, lighter weight batteries, to studying climate change and finding cures for disease. Titan is a milestone on the path to exascale computing, which targets building a 1,000 petaflops supercomputer.

Titan is operated by Oak Ridge National Laboratory, part of the U.S. Department of Energys network of research labs, as an open-science system. This means it is available to researchers from academia, government laboratories, and a broad range of industries who will use Titan to model physical and biological phenomena and seek breakthroughs faster than possible by experimentation alone.

Supported by the energy efficiency and cost-effectiveness of the Tesla K20 GPU, Titan is more than 10 times faster and five times more energy efficient than its predecessor, the 2.3-petaflops⁽²⁾ Jaguar system, while occupying the same floor space. Had Oak Ridge upgraded Jaguar by simply expanding its CPU-based architecture, the system would be more than four times its current size and consume more than 30 megawatts of power.⁽³⁾
 
"Basing Titan on Tesla GPUs allows Oak Ridge to run phenomenally complex applications at scale, and validates the use of accelerated computing to address our most pressing scientific problems," said Steve Scott, chief technology officer of the GPU Accelerated Computing business at NVIDIA. "You simply cant get these levels of performance, power- and cost-efficiency with conventional CPU-based architectures. Accelerated computing is the best and most realistic approach to enable exascale performance levels within the next decade."

Titan development began three years ago with Oak Ridges decision to upgrade Jaguar, the previous open science system leader and a former world No. 1 most powerful supercomputer. The upgrade includes the Tesla K20 GPU accelerators, a replacement of the compute modules to convert the systems 200 cabinets to a Cray XK7 supercomputer, and 710 terabytes of memory.

"Science and technology have always been our primary goal, and Titan is a groundbreaking tool that will allow researchers worldwide to leverage GPU-accelerated computing to make unparalleled breakthroughs," said Jeff Nichols, associate laboratory director for computing and computational sciences at Oak Ridge National Laboratory. "The new Tesla GPU accelerators offer the performance and energy efficiency that enable Titan to scale to unprecedented performance levels without consuming the energy equivalent of a small city."


About NVIDIA Tesla GPUs NVIDIA Tesla GPUs are massively parallel accelerators based on the NVIDIA CUDA® parallel computing platform and programming model. Tesla GPUs are designed from the ground up for power-efficient, high performance computing, computational science and supercomputing, delivering dramatically higher application acceleration for a range of scientific and commercial applications than a CPU-only approach.

Sony Vaio Z Series notebook, this machine comes with the processing power of Intel Core i7-2620M Core i7, but the CPU 2 core 4 Threads is the straight talk, it is a lower version of the Core i7 itself, which I look. VAIO notebook is that it needs to conserve energy in times of need to hold the notebook to use it more for me outside. Do not force it. The card is a Intel HD Graphics 3000, but there are isolated Docking AMD Radeon HD 6730M graphics card to use in times of heavy usage such as playing games, etc. RAM machine to 8 GB DDR3-screen 13.3-inch FULL HD storage as SSD 128 GB 2 balls made of RAID 0 is 256 GB, this is probably the cause of my Sony Vaio Z Series notebook, this machine is worth it. this size. The other ports to Windows, it comes to the Docking facilities are equipped with AMD Radeon HD 6730M graphics card and Drive Blu-Ray.

Refurbished laptop computer are not essentially spruced up second-hand apparatus, they are supplementary regularly returned harvest that have some small mark or wrapping problems. When a notebook or laptop computers are returned to the producer it is inspect and evaluate, given small maintenance if essential and repackaged. The high-quality news is the price tag is much inferior than for a new, unblemished model. It is not uncommon to save half the recommended retail price. These refurbished laptop computers are brilliant excellence and value and have a extremely low return rate to the producer, which indicate customer satisfaction. Like new, full price products, refurbish laptop computers come with guarantee and a warranty. All the main manufacturer of laptops offer refurbishes apparatus and you can often find these offerings by doing an Internet search.
Refurbished notebook come with an in use system, though they may or may not approach with an supplementary software bundle such as Microsoft Office so it is significant to be extremely obvious on what the price cover. Refurbished laptop computer can do the whole lot a new, full priced computer can do. The key is to be clear on the size of the hard drive, the amount of RAM the CPU comes with and the velocity and type of processor. If you identify these things you can compare the price of the refurbished product with a new one obtainable at a retail outlet. However, there can be a very real variation between the quality of a refurbished computer from the producer and a private dealer who is refurbishing laptops and notebooks. company refurbished apparatus based on minor defects in appearance and wrapping offer little or no risk to the buyer and are suggested for their value, though there are low price refurbish laptops which are obviously second hand and given a new lease on life. These computers can frequently be purchase at very sensible prices but you would have to be extremely careful that the isolation that refurbished the apparatus created a high quality produce at a very realistic price, backed up by guarantee and warranty.

Standout Features

• Intel Core 2 Duo Processor
• Microsoft Windows 7 Home Premium
• 4GB RAM Memory
• Wi-Fi and Bluetooth

At just 3.5 pounds and a mere one inch thick, the Lenovo IdeaPad U350 has the look of an ultra-portable netbook. It has a 13.3-inch widescreen, LED backlit display and an ambient light sensor that automatically adjusts screen brightness in response to surrounding lighting conditions. As handy as the minimal size and weight are, they can imply being rather lightweight in computing power as well. Thanks to a couple of important upgrades from Lenovo, the device has moved significantly towards being a serious laptop computer.

Most notable is the upgrade of the CPU from an Atom processor, characteristic of Netbooks, to an Intel Core 2 Duo Su7300 running at a respectable 1.3GHz clock speed. More significantly, as a dual core chip, it is essentially two distinct processors built into one. Further, each core has two threads so it’s rather like data is flying down a four lane highway rather than the single path that had been available with the previous processor. In short, it represents a tremendous increase in the amount and speed of data processing.

Nearly as significant is the leap from Windows Vista which was previously offered as the operating system to the far superior Windows 7 Home Premium. This is an upgrade that loads of Vista users willingly pay for so it really is a tangible bonus for Lenovo buyers.

Network and internet connectivity is always an issue for laptop users and this unit has the issue covered. It has a gigabit Ethernet port for wired connection but more practically provides wireless internet and LAN access via Wi-Fi including the high speed 802.11n protocol. Bluetooth, both mono and stereo, is also furnished. This is handy for users who would like to connect to interface with wireless devices like a mouse, cell phone or even headphones.

The U350 comes with 4GB of RAM memory which is pretty substantial for a small laptop. Storage is provided by a 320GB hard disc drive. One item that is lacking is an optical disc drive. That helps in the size and weight category means that an external drive would have to be connected in the event that a user needs to transfer information to or from a DVD or CD.

The computer includes an integrated 1.3-megapixel web cam which is typical of this category. An unusual use of the camera, however, is the Lenovo VeriFace facial recognition system which affords a level of security beyond simple password entry.

The device is covered by a one year limited parts and labor warranty which includes depot level repair if required. That can be upgraded to include in-home service and accidental damage protection if desired. Coverage can be expanded to two or three years at additional cost.
