Stacking Stairs Against the Memory Wall

Apr 2, 2013 |

With ever-mounting CPU advancements that promise superior performance, the blame for lousy delivery on those chip promises lies squarely on memory. This problem isn’t just a matter of application performance—it’s also a matter of efficiency. This week Micron with partners Intel and others, including Altera, IBM, ARM, Xilinx and others…..

The Bandwidth Bottleneck

Aug 16, 2012 |

Lack of high bandwidth connectivity can severely hinder the use of cloud services for HPC workloads.

The Weekly Top Five

May 26, 2011 |

The Weekly Top Five features the five biggest HPC stories of the week, condensed for your reading pleasure. This week, we cover the NC State effort to overcome the memory limitations of multicore chips; the sale of the first-ever commercial quantum computing system; Cray’s first GPU-accelerated machine; speedier machine learning algorithms; and the connection between shrinking budgets and increased reliance on modeling and simulation.

Terascale Memory Challenges and Solutions

Dec 6, 2010 |

In contrast to the previous decade, CPU clock rates are scaling slower over time due to the power constraints. However, the number of transistors per silicon area continue to increase roughly at the rate of Moore’s Law. Therefore, CPUs are being designed and built with an increasing number of cores, with each core executing one or more threads of instructions. This puts a new kind of pressure on the memory subsystem.

Cloud Storage Will Be Limited By Drive Reliability, Bandwidth

May 17, 2010 |

Drive reliability and bandwidth will limit cloud adoption–a problem that may never get solved. Bandwidth will get cheaper, but drive reliability hasn’t improved much, and data will likely continue to grow faster than bandwidth
