NVIDIA made huge efforts to implement their computing accelerators with CUDA support and Tegra processor with ARM architecture into the latest supercomputers . The advantage of processors with ARM-architecture is the high energy efficiency. Accelerators based on computing graphics processors already proved their efficiency in the segment of supercomputers - they are used extensively in many systems outside the top ten world leaders.
Accordint to an interview with Sumit Gupta , director of Tesla product marketing at NVIDIA , the only advantage of systems based on x86-compatible processors is the ability to run faster in operating systems like Windows, includes prompt responses to unpredictable user actions. These problems are under x86-compatible processors optimized first.
Processors with ARM architecture can achieve higher efficiency in the ratio of performance per watt, NVIDIA believe that they are optimal base for future supercomputers . In addition to the processor Tegra, the company plans to develop the so-called Project Denver - a hybrid product that combines traditional and computer graphics processor with ARM-core architecture.
