Interesting. I just read the article Can Cloud Computing Reach the Top500?, which concludes that EC2 won't crack the top 500. I wonder what changed. http://www

- amock 16y agoI think the two big changes are that the nodes have 10Gb network cards and full bisection bandwidth. They're also HVM instead of PVM but I don't know how much that matters for this benchmark.
- RK 16y agoInternode bandwidth seemed to be the limiting factor cited in the paper, so that makes sense.
- pbh 16y agoIt looks like they are using extra-large standard and extra-large high CPU instances rather than the more recent quadruple extra-large "cluster compute" instances. Maybe that's the reason? (EDIT: Though amock seems to have said it better than me.)
