The Quad-cores Are Here

The core wars, begun they have

This week at the Intel Developers Forum (IDF) several vendors are showing the latest in multi-core fashion -- the quad-core Xeon. Dubbed the Clovertown, this quad-core beastie is mentioned as part of Intel's new Core™ Microarchitecture". In particular, Appro is demonstrating a 1U server with two quad-core Clovertown processors. That is a total of eight cores in a standard rack-mount enclosure. I happen to know that they also have two of these systems connected via a Mellanox infiniband HCA and they are running the NAS Parallel Benchmark Suite under Linux on all 16 cores. Rumor also has it that the monkey who set up the demo is running GKrellM on both nodes and 16 little windows show busy little cores. "What about numbers?, you ask. Stay tuned, real numbers for real cluster applications will be available in November at SC06

And, by the way, hypothetically speaking, if a certain Cluster Monkey happened to have these two nodes for a few more weeks, what would you like to see him run on it? (add your suggestion as a comment) That is, of course, hypothetically speaking.

IBM Super-Cell Machine

They named it Roadrunner, wonder if they include any Acme earthquake pills or rocket sleds. Just a thought.

IBM has announced the "worlds fastest supercomputer" that is to be built from Cell processors. Normally, I don't post or comment on fastest supercomputer headlines, but this announcement represents an interesting take on the HPC market. First, I think they forgot to tell us what program(s) this machine will run the fastest. My guess is it will be HPL and a trip to Top500 glory, but I could be wrong and that is not what really matters here.

A Discussion On Parallel Languages

There is an interesting discussion about Parallel Languages over at the IEEE Technical Committee on Scalable Computing. The discussion was initiated by Greg Pfister of IBM (And author of In Search of Clusters.) The excellent question he posed is below (click Read More) Your thoughts are welcome here as well.

Learn About Clusters: Beowulf 101

Want to be a cluster maven? Ever wonder where to learn all those secrets only the those cluster geeks seem to know? Well now you can. The Advanced Research Computing (ARC) team at Georgetown University's is offering Introduction to Beowulf Design, Planning, Building and Administering. From the looks of the syllabus they are covering all the right stuff. If you are so moved, add a comment on what courses you think the HPC cluster community needs.

16,128 Cores and Counting

Appro International has just announced the sale of a 16,128 core cluster to Lawrence Livermore National Labs (LLNL). The number of cores is quite impressive as it will exceed ASC Purple and be the second largest system behind IBM's Blue Gene. The LLNL scorecard is here. The core density is accomplished by using quad-socket motherboards with dual core Opteron processors. The full press release is below.
