Cray built the worlds first production petaflops engagement with the Cray XT5â„¢ supercomputer in 2009. Now with the Cray XE6â„¢ system, Cray is raising the expectations for high performance computing once again. Redefining Supercomputing The Cray XE6 supercomputer takes the proven Cray XT5 infrastructure and incorporates it with two innovative sophisticated technologies: AMDs powerful multi-core processors and the revolutionary similitudeâ„¢ interconnect. The result is a system that brings production petascale to a wider HPC community and fundamentally changes how Cray systems communicate. sagacious to scale to oer 1 million processor cores, every aspect of the Cray XE6 supercomputer from its industry-leading resiliency features to its host of scalabilityboosting technologies has been engineered to meet sciences ever-toughening demands for scalability, reliability and flexibility. Scalable Performance counterpart Scalable link The Gemini interconnect is the hea rt of the Cray XE6 system. Capable of tens of millions of MPI messages per second, the Gemini ASIC is knowing to attendant current and future massively multicore processors. Each dual-socket node is interfaced to the Gemini interconnect through HyperTransportâ„¢ 3.0 technology.

This direct connect architecture bypasses the PCI bottlenecks inborn in commodity networks and provides a peak of over 20 GB/s of injection bandwidth per node. The Gemini routers connectionless protocol scales from hundreds to hundreds of thousands of cores without the increase in buffer memory demand in the point-topoint connection met hod of commodity interconnects. The Cray XE6! network provides industry-leading sub-microsecond latent period for unconnected puts and 1-2 microsecond latency for most other point-to-point messages. An internal full point pitch engine is available to provide high bandwidth and safe overlap of computation and communication for long messages. Advanced features let in die hard for one-sided communication primitives and...If you want to bulge out a sound essay, order it on our website: OrderCustomPaper.com
