IBM regains supercomputer bragging rights

Blue Gene fades...: This article kind of irks me in places...like usual ZDNet writing, the facts contradict themselves. Referring to IBM's Blue Gene architecture, the article says that the design allows doubling the number of processors to nearly double performance (the holy grail of supercomputing is linear scalability). Just a bit further on, the figures are given for the #4 & #8 machines on the list, both IBM Blue Gene machines. If my calcs are correct, there's a 20% hit for the doubling of # of processors that they did from one to the other. That's not linear.; Posted by: techboy_z Posted on: 06/21/04 You are currently: a Guest | Members login | Terms of Use
