Supercomputer made from mobile devices

Exaflop supercomputer made from mobile CPU is being completed to expect a breakthrough in the global computing technology. Several European technology corporations are looking to perfect the use of supercomputer processor’s CPU smartphones and tablets. Do not just stop at the super computer that they are also intended to speed towards exaflops (trillion calculations / second) faster than 1000 times the current performance. Super Computing term was first used in 1920 to refer to the spreadsheet (tabulators) IBM‘s big. In the years 1970-80, the Cray supercomputer not look like much different a big PC business, and only contains the processor has been designed to create the fastest computing speed.

1990-200 years, personal computers and laptops has dominated the daily work of the supercomputer also has become a combination of hundreds of millions of PC processors, server. The fastest supercomputer in the world today is China’s Tianhe-2, with 3.1 million people, but Intel Xeon processor performance will be around 5% compared to an exaflop machine.

So, in an era of tablets and smartphones, the performance-based supercomputers from di DongG tools today is only a matter of time. The ARM is designed to run on smartphones and tablets compact makes a supercomputer is created from it can to speed and less power.

Current is also the era of high computing performance, also known HPC (High Performance Computing) is often limited by the equipment and the ability to power consumption, which means that the limited scalability of the super computer.

Mont-Blanc project in 2011 at the Barcelona Supercomputing Center is regarded as one of the efforts to reduce the load limits of supercomputing. This supercomputer using 256 quad-core processor NVIDIA Tegra 3, 256 processor and GeForce 520MX 1TB DDR3 RAM to operate. With such configuration, the machine can calculate the 38 teraflops per second, but only consuming 1W per 7.5 gigaflops power.

Up to the present time, the project has 14 partners and 22 million euros for development in order to provide finished products in 2015.
Currently supercomputer is equipped with dual-core CPU and Samsung’s Exynos 5 SoC system (System on Chip – integrates all components and electronic systems on a chip) of the ARM Cortex-A15 . Energy consumption capacity of this supercomputer or only about 1/30 versus 1/15 HPC systems today.

Jean-François Lavignon, the man behind the project, said Mont-Blanc, the current Intel x86 CPU processors are still the best performance for most supercomputers. And he hopes that the x86 processors in combination with processor like the GPU acceleration will continue to dominate the Top500 list of supercomputers with the world’s fastest performance. However Lavignon said supercomputers based on ARM seems to be a wise investment for the future.

Jack Dongarra, a computer science professor at the University of Tennessee said that the ARM processor cores is an interesting thing, but in the near future is difficult to reach Exascale supercomputer architecture. 12th month, Japan has announced plans to create exaflop supercomputers in 2020 with the use of conventional processors. One of the biggest obstacles of supercomputers that consume energy.

Exascale Systems Japan will use the processor on the market with the GPU will consume about 30-40 megawatts of electricity. One megawatt per year in the US costs about $ 1 million. So only use energy costs were at about 30-40 million / year, a sizeable figure should reduce the load in the future.
