Submission + - Eight-core computing

Alan writes: FiringSquad just posted a review of the Intel V8 Platform, a dual quad-core Xeon system. With 8 total CPU cores, this system has more computational horsepower than most of the supercomputers on the original Top 100 List from 1993! What was surprising is that more and more applications are taking advantage of multicore processors — Excel 2007 is multicore aware and it makes good use of the additional processing power. However, even embarassingly parallel problems failed to scale well on 8 cores when memory bandwidth is limited.

To do two things at once is to do neither. -- Publilius Syrus
