The combination of quad-core Opterons and DDR Infiniband is re-landscaping the HPC terrain and is propelling the largest clusters to the top of the high performance heap. A rash of recent announcements of big system purchases suggests good times ahead for HPC cluster vendors. Or does it?
As Intel and AMD take a break from beating each other about the quads, this week we'll turn our attention to software -- specifically, parallel programming. Yes, multicore processors, GPUs and FPGAs are all the rage; but without applications to run on them, they're just pretty etchings.
Every year we let the HPCwire readership decide which are the most innovative and successful organizations, products and programs in the HPC industry. This time around we're going to do it a little differently. We've set up a short web survey that makes it super-easy to submit your nominations.
High-end computing aficionados had plenty of entertainment this week. In San Francisco, the Intel Developer Forum offered a smorgasbord of technology talks about all things Intel. And in New York, the HPC on Wall Street conference focused on the financial industry's obsession with automated trading and low latency. Editor Michael Feldman recaps some of the bi-coastal festivities.
AMD's public relations blitz for its new quad-core processors is winding down now. While the impact of the latest Opterons in the overall server market will take some time to develop, their effect in the HPC universe will be almost instantaneous.
Will AMD find true happiness in Barcelona? Will Xeon break Opteron's heart? What evil lurks beneath the Front Side Bus? If this sounds like the premise for some weird, high-tech soap opera, that's because it is. The Intel-AMD feud has been going on for over 20 years and the participants show no signs of reconciliation.
As the formal introduction of AMD's new quad-core "Barcelona" processor approaches, the folks at Intel are trying to grab the limelight with a few well-timed announcements of their own. The fun never stops in x86-land.
If you thought computing was just getting interesting with four cores, what happens when the chipmakers start delivering 100-core chips with multiple types of processing units? Although the multicore revolution is just starting, some are already thinking about what comes next.
As AMD prepares to do battle with Intel in the quad-core arena, it's faced with an uncomfortable reality: Intel is about to jump to 45nm, the next process technology level, with its Xeon processors, just as AMD is pushing its 65nm Opterons out the door.
On Wednesday, the National Science Foundation (NSF) announced the award recipients for two highly coveted petascale supercomputers. But questions are being raised about the validity of NSF's proposal review process.
