Because of the volume of news in this, the week before SC, I've shortened the entries somewhat in an attempt to keep this summary shorter than book 7 of the Harry Potter series. You can always find more detail by following the links for each story.
As always, I present a collection of highlights, selected totally subjectively, from this week's HPC news stream as reported at insideHPC.com and HPCwire.
>>10 words and a link

>>Cray announces XT5 line of supers
Cray announced the latest installment in the XT series of scalable supercomputers, the XT5 family. The new Cray XT5 massively parallel processor (MPP) system incorporates a new compute blade that will quadruple local memory capacity, double processor density and improve energy efficiency. The XT5 family also includes the first hybrid supercomputer, the XT5h, with support for vector and FPGA blades alongside the Opteron blades in a single system fabric. More at http://insidehpc.com/2007/11/06/cray-announces-xt5-series-supercomputers/, and elsewhere in this edition of HPCwire.
>>HP announces Accelerator and Multi-Core Optimization programs
HP has announced two new HPC performance programs. The new HPC Accelerator program gives accelerator vendors a path to qualify their offerings with ProLiant and BladeSystem hardware. Current partners include ClearSpeed, Celoxica, NVIDIA, AMD, RapidMind and Mitrionics.
The Multi-Core Optimization Program (MCOP) was announced in June, and has been expanded. From the press release (http://www.hp.com/hpinfo/newsroom/press/2007/071101a.html):
The program brings together developments from HP and its partners to provide open, non-proprietary solutions that enhance multi-core performance across a variety of industry-standard HPC architectures, platforms and operating environments. By optimizing multi-core solutions, customers can maximize application performance on multi-core systems, enabling larger simulations and more data analysis that is necessary to achieve their engineering, science and analytical goals.
New members of the program include: Allinea, Interactive Supercomputing, The Portland Group, RapidMind, Stanford Pervasive Parallelism Lab and Visual Numerics.
More information on both programs at http://insidehpc.com/2007/11/05/hps-accelerator-and-multicore-optimization-programs/.
>>RapidMind revs multicore development platform
RapidMind announced this week that they've released version 3.0 of their Multi-core Development Platform, an application development suite designed to help coders get the most performance out of multicore platforms from Intel and AMD as well as GPGPUs and the Cell.
>>Allinea's DDT available on the XT
This week they've announced that their flagship parallel debugging tool, the Distributed Debugging Tool (DDT), is now available for the Cray XT4 and 5.
>>TotalView previews reverse debugging
TotalView announced this week they'll be previewing "reverse debugging" at SC07 next week. The press release (http://www.totalviewtech.com/press_release.htm?id=90) states that the new reverse debugging features will allow developers to:
- Capture and replay the exact behavior of the program from any point in the past during a single debugging session.
- Step backward from crashes and out of functions to see what went wrong.
- Jump forward and backward to examine and compare any set of points along the captured execution sequence.
- Replay thread context switches exactly as they happened.
- Seamlessly and clearly switch between record mode and replay mode.

The 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.

Supercomputers at the Department of Energy’s National Energy Research Scientific Computing Center (NERSC) have worked on important computational problems such as collapse of the atomic state, the optimization of chemical catalysts, and now modeling popping bubbles.
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.
04/15/2013 | Bull | “50% of HPC users say their largest jobs scale to 120 cores or less.” How about yours? Are your codes ready to take advantage of today’s and tomorrow’s ultra-parallel HPC systems? Download this White Paper by Analysts Intersect360 Research to see what Bull and Intel’s Center for Excellence in Parallel Programming can do for your codes.
In this demonstration of SGI DMF ZeroWatt disk solution, Dr. Eng Lim Goh, SGI CTO, discusses a function of SGI DMF software to reduce costs and power consumption in an exascale (Big Data) storage datacenter.
The Cray CS300-AC cluster supercomputer offers energy efficient, air-cooled design based on modular, industry-standard platforms featuring the latest processor and network technologies and a wide range of datacenter cooling requirements.
