>>AMD finally launches Barcelona
There was a lot of coverage of what has been characterized as a "make or break" launch this week by AMD of their long-awaited quadcore Opteron chip, Barcelona.
The chips are six months late and a few hundred MHz short, but better late than never I always say. It's reasssuring to know that hype didn't die when Clinton left the White House; AMD is immodestly referring to their new chip as "The World's Most Advanced x86 Processor." Time will tell. Early indications are that the new chips best the currrent crop of Intel Xeons in memory bandwidth and performance per watt. AMD also touts the new Opteron's floating point performance, but Jon Stokes at Ars Technica thinks the chip's FP muscle may fall short of expectations:
...Xeon's bandwidth bottleneck isn't nearly so pronounced in two-socket configurations as it is in four-socket configurations, so at two sockets the two processors' respective floating-point ALUs can duke it out on a relatively more level playing field. In this scenario, Xeon's superior floating-point and vector hardware carries it, and gives it the 3D rendering scores that match and beat Barcelona's.
Find Jon's article at http://arstechnica.com/news.ars/post/20070910-barcelonas-out-and-the-reviews-are-out.html.
In any case, Intel will respond soon with its 45nm Penryn processors.>>Vendors respond to Barcelona launch
Vendors took advantage of all the extra planning time they had courtesy of Barcelona delays to make sure they had their Barcelona products all lined up and ready to go. And they spent this week announcing them. In no particular order, here are the most relevant ones I saw along with links to product details:
>>Rumor: Rambus and Sun
Recall the last time I posted a Sun acquisition rumor (http://insidehpc.com/2007/03/23/sun-and-rackable/), it turned out to be way wrong. You've been warned.
The business journals are reporting this week on speculation that Sun is warming up to buy Rambus (http://biz.yahoo.com/bizj/070912/1519513.html?.v=1):
Shares of Rambus Inc. rose more than 6 percent Wednesday on speculation that a takeover may be on the table. Los Altos-based Rambus (NASDAQ:RMBS) closed the day at $16.71 after going as high as $17.15. One of the potential suitors cited by traders and analysts was Santa Clara-based Sun Microsystems Inc. (NASDAQ:JAVA).
Who's Rambus? As stated on their website, "Rambus is one of the world's premier technology licensing companies specializing in the invention and design of high-speed chip interfaces."
>>Sun sets on CFS
Several weeks ago we had the announcement (http://insidehpc.com/2007/07/14/cfs-moves-lustre-to-zfs/) that CFS was moving its commercial Lustre implementation to use ZFS as a backend.
This week the other shoe dropped as Sun bought the whole company, lock, stock and barrel. Read the press release at http://www.sun.com/aboutsun/pr/2007-09/sunflash.20070912.2.xml.
It will be interesting to see what impact this has on Sun's competitors who also offer Lustre (IBM comes to mind, for example). Will they find something else or let a big part of their business success depend upon Sun? Probably not that last one.

The world's largest supercomputers, like Tianhe-2, are great at traditional, compute-intensive HPC workloads, such as simulating atomic decay or modeling tornados. But data-intensive applications--such as mining big data sets for connections--is a different sort of workload, and runs best on a different sort of computer.

Researchers are finding innovative uses for Gordon, the 285 teraflop supercomputer housed at the San Diego Supercomputer Center (SDSC) that has a unique Flash-based storage system. Since going online, researchers have put the incredibly fast I/O to use on a wide variety of workloads, ranging from chemistry to political science.

The advent of low-power mobile processors and cloud delivery models is changing the economics of computing. But just as an economy car is good at different things than a full size truck, an HPC workload still has certain computing demands that neither the fastest smartphone nor the most elastic cloud cluster can fulfill.

For all the progress we've made in IT over the last 50 years, there's one area of life that has steadfastly eluded the grasp of computers: understanding human language. Now, researchers at the Texas Advanced Computing Center (TACC) are utilizing a Hadoop cluster on its Longhorn supercomputer to move the state of the art of language processing a little bit further.

Titan, the Cray XK7 at the Oak Ridge National Lab that debuted last fall as the fastest supercomputer in the world with 17.59 petaflops of sustained computing power, will rely on its previous LINPACK test for the upcoming edition of the Top 500 list.
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.
