USA - Titan Cray XK7 is the world’s most powerful supercomputer

Oak Ridge, Nov 15 (TruthDive): U.S. supercomputer called Titan the Cray XK7 at Oak Ridge National Laboratory, 10 times more powerful than the last lab machine has claimed the title, 'most powerful supercomputer' in the world.

The U.S. retained the top slot of world's fastest computer in June this year with the Sequoia, Linux-powered which was installed at the Lawrence Livermore National Lab.

Titan, which was funded by the American Department of Energy, is used for study in energy, efficient engines, climate change, materials and scientific research. Titan, a Cray XK7 system having 200 cabinets, reached the speed of 17.59 petaflops (17.59 million billion calculations per second).

The previous record of 16.32 petaflops, held by Sequoia, a supercomputer at Lawrence Livermore National Laboratory in California, is used to study nuclear attacks. The Cray machine Titan reportedly has a peak capability of more than 27 petaflops.

Titan is an upgrade of a Cray system called Jaguar with added AMD chips but gets its best speed from a new Nvidia chip family that is based on the technology used to provide sophisticated graphics in video games. The new Titan contains 18,688 processing nodes each built from a 16-core AMD Opteron 6274 processor and a memory of 710 terabytes.

Titan is powered by 560,640 processors, which is actually less than the 1,572,864 cores that power Sequoia.

U.S. supercomputers had dropped behind China's Supercomputer, Tianhe-1A and Japan's Fujitsu K Computer in 2009, but staged a comeback by installing Sequoia in 2012. The machine Titan has snatched the top position in the Top 500, a closely-watched global league of the fastest supercomputers.

Another U.S. machine to debut on the Top 500 list was Stampede, a Dell supercomputer at the University of Texas, which was ranked No. 7.

Researchers claimed 251 of the top 500 list of systems were in the US, with 105 in Europe and 123 in Asia, including 72 in China. 469 out of 500 machines on the list are currently powered by Linux. (http://is.gd/kTk3YY )

Mining Group begins drilling of newly discovered copper-gold target in Mindanao Philippines

Mining Group Limited (ASX: MNE) is an ASX listed, is an Australian based exploration company established to explore, evaluate and acquire commercially significant resource projects in Australia and overseas

Mining Group (ASX: MNE) has begun diamond drilling to test the copper and gold system recently discovered at Tagpura North, part of the 80% owned Comval copper-gold project in the Compostela Valley Province, Mindanao, Philippines.

Tagpura North lies about 1 kilometer north of the historic Tagpura East resource.

Mining Group previously discovered extensive gold rich skarn and diorite at Tagpura North with peak assays up to 3.58% copper and 12.52 grams per ton (g/t) gold from rock chips.

The company has defined a 500 meter by 300 meter target zone that is open along strike to the northeast which is a significantly larger footprint than the Tagpura East resource.

It has returned some of the highest copper and gold grades seen within the project area from rock chip samples to date.

Importantly, the newly discovered Tagpura North skarn, located only 750 meters from the Tagpura open pit mine, has the potential to further build on the resource base.

Last month Mining Group delivered its first resource for the project of 32.675 million tons at 0.42% copper and 0.13g/t gold for 136,100 tons of contained copper and 138,900 ounces of contained gold.

Importantly, this includes a high grade resource of 8.987 million tons at 0.63% copper and 0.2g/t gold, which is all at surface and expected to have a low stripping ratio.

Drilling is expected to continue over the next two to three months.

Zeff Reeves, managing director, told Proactive Investors last month the drilling of the Tagpura North Target will involve two to four holes, depending on how the first two look.

Over the broader Comval Project, Mining Group is currently assessing its resource models and will be looking at further drilling on the Tagpura East deposit and possibly Kalamatan once ground geophysics are completed.
