The Weekly Top Five features the five biggest HPC stories of the week, condensed for your reading pleasure. This week, we cover the computing power on display at SC10′s Student Cluster Competition; the University of Portsmouth’s new supercomputer; IBM Watson’s SUSE Linux platform; multicore advances at North Carolina State; and Intel’s new approach to university funding.

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.
