It seems that the HPC world is still recovering from the news-fest that surrounds SC every year. But good stuff did happen this week, and so here is this week's collection of highlights, selected totally subjectively, from the HPC news stream as reported at insideHPC.com and HPCwire.
>>10 words and a link
Cornell finds new human genes with HPC;
Presentations from the Sun HPC Consortium online;
HP Q3 numbers up thanks to Itanium;
NCSA announces workshop on datacenter design;
AnandTech: Quad Xeons outperform quad Opterons unless memory is stressed;
>>Great news for the next generation of HPC
I'm really excited to see the raft of recent announcements for fellowships in HPC and scientific computing.
Here are a few of the ones I've seen lately. If you've seen others, email me links at email@example.com, and I'll put together a cheat sheet and post it at the site permanently for interested future applicants.
In the meantime if you're interested in these opportunities you can find links to more information at http://insidehpc.com/2007/11/29/great-news-for-the-next-generation-of-hpc/.
>>HPC Server 2008 Memory Requirements
I stumbled upon an interesting post on a Windows Vista blog site regarding the posted memory requirements for the various Windows operating system flavors. It seems that Windows HPC Server 2008 actually requires less memory to run than the standard version of Windows Vista. Windows Vista requires *at least* 1GB of memory (except for the 'Home Basic' version which will run on 512MB). Windows HPC 2008 can run on 512MB.
Granted, these are minimum values. The article also goes on to point out that HPC 2008 would prefer to run with 1.5-3GB in a 32-bit environment and greater than 4GB in the 64-bit flavor.
>>Rambus shooting for 1 TB per second memory by 2011
The DailyTech is carrying news of Rambus Inc.'s new hardware plan, to be announced tomorrow: a new memory initiative aimed at delivering 1 terabtye per second of memory bandwidth to the market by 2011.
Rather than simply increasing the clock speed of memory to achieve higher output, Rambus looks to boost bandwidth with a 32X data rate. Just as DDR memory technologies doubles transfer on a single, full clock signal cycle, Rambus' proposed technology is able to data at 32 times the reference clock frequency. With 32X technology, the memory company is targeting a bandwidth of 16Gbps per DQ link with memory running at 500MHz. In contrast, today's DDR3 at 500MHz achieves a bandwidth of 1Gbps
While Rambus is (naturally) positioning this as a boon for gamers, it will be a big deal for us as well. Full story at http://www.dailytech.com/article.aspx?newsid=9771.

he study of climate change is one of those scientific problems where it is almost essential to model the entire Earth to attain accurate results and make worthwhile predictions. In an attempt to make climate science more accessible to smaller research facilities, NASA introduced what they call ‘Climate in a Box,’ a system they note acts as a desktop supercomputer.

At some point in the not-too-distant future, building powerful, miniature computing systems will be considered a hobby for high schoolers, just as robotics or even Lego-building are today. That could be made possible through recent advancements made with the Raspberry Pi computers.

When it comes to cloud, long distances mean unacceptably high latencies. Researchers from the University of Bonn in Germany examined those latency issues of doing CFD modeling in the cloud by utilizing a common CFD and its utilization in HPC instance types including both CPU and GPU cores of Amazon EC2.

Program provides cash awards up to $10,000 for the best open-source end-user applications deployed on 100G network.
05/10/2013 | Cleversafe, Cray, DDN, NetApp, & Panasas | From Wall Street to Hollywood, drug discovery to homeland security, companies and organizations of all sizes and stripes are coming face to face with the challenges – and opportunities – afforded by Big Data. Before anyone can utilize these extraordinary data repositories, however, they must first harness and manage their data stores, and do so utilizing technologies that underscore affordability, security, and scalability.
