The Week in Review

by John E. West, for HPCwire

Here's a collection of highlights, selected totally subjectively, from this week's HPC news stream as reported at insideHPC.com and HPCwire.

>>ORNL Jaguar completes upgrade

Oak Ridge National Lab's Jaguar supercomputer just completed its latest upgrade. The Cray XT3/XT4 system was previously chewing through 119 Tflops. With this upgrade, the new peak performance rate has jumped to 263 Tflops.

Where does this new upgrade position Jaguar for the next Top500 list? Well, currently the system runs at 119 Tflops peak and roughly 101 Tflops max [as quoted by the Nov07 Top500 list]. If one does the math, you're looking at a system with ~85 percent efficiency on Linpack. Now, at 263 Tflops peak, the max should come in right around 223.55 if they maintain the same efficiency [which is often very difficult]. If the Top500 list were not to change at all this June, this would place Jaguar in the number two slot.

Regardless of how the list will change this summer, Jaguar will most certainly be competitive within the Top10. You can check out insideHPC's Top500 rumor mill to get the scoop on some other contenders.

>>The Cluster Challenge: growing HPC one contest at a time

SC08 will once again bring the Cluster Challenge to university teams from around the world. Teams of undergraduates will compete on the exhibit floor, using clusters of their own design, to run a workload of real-world problems. The contest is simple, but the idea is big: users of all skills, and organizations of all sizes, can now own tools that just a few years ago were limited to just a few of the world's wealthiest R&D organizations. The Challenge aims to demonstrate just how accessible all this horsepower really is.

The Cluster Challenge, now in its second year as part of the technical program at the annual Supercomputing conference, is billed as an event to showcase the computational power that even inexpensive clusters have and, according to the Web site, the ability of potential users around the world "to harness open source software to solve interesting and important problems." The competition pits teams of undergraduates against one another to see who can build and configure a cluster that accomplishes the most work using real computational codes in the least amount of time.

Check out the rest of the story here.

>>UCF lands first supercomputer

The University of Central Florida has landed its first supercomputer. Thanks to a $2.6M grant from the Army, UCF has purchased a new super from IBM. The new cluster tips the scales with 224 processors, 512GB of memory and 22.2TB of storage. There is also an upgrade planned for this summer to triple the compute and memory capacity.

"This is a great opportunity for UCF and the simulation industry," said Michael R. Macedonia, general manager of the Orlando unit of Forterra Systems Inc., a high-tech partner with the college. "People need to understand how important it is to have a supercomputer of this class in Central Florida. This will allow UCF to press the limits of science and attract new business to the region as well."

The initial compute workloads will include defense simulation training [hence the Army dollars attached]. Future workloads will include medical simulation, civil engineering and nanoscience.

>>A glimpse of RoadRunner

ComputerWorld has posted an interesting peek into what could become the fastest supercomputer on the planet as measured by Linpack this June. Rumors have been circulating that RoadRunner was going to take a stab at the top spot. IBM's fabled RoadRunner is in the process of receiving Phase3 of an upgrade to push its peak performance over a petaflop. 6,000 square feet of floorspace, 250 tons of equipment and lots of IBM logos have gone into building this behemoth. How sure is IBM that they will be able to do so?

"We will break the petascale," [Don] Grice [Chief Engineer of RoadRunner] told Computerworld.

According to sources inside IBM, they are quite simply contractually obligated to do so. This, of course, alludes to the fact that RoadRunner will be over 2x the current speed of its cousin, BlueGene/L at Livermore [currently 478 Tflops].

Computerworld has also posted a series of pictures of RoadRunner taken from within IBM's lab in Poughkeepsie, N.Y.

IBM Looks to Tap Massive Data Streams

Modern civilization is positively drenched in data, some of which needs to be dealt with in real time to be of any value. Businesses, especially in the financial industry, have long recognized this, and have been building custom systems to collect, analyze, and react to information as it is captured. IBM thinks the time is right to generalize these approaches into a new field of computing -- and a new business -- it calls stream computing.

Gravity Attracts a GigE HPC Cluster

Not all supercomputing rides on InfiniBand or proprietary interconnects. For technical applications that decompose neatly into loosely-coupled threads, a big cluster with vanilla Gigabit Ethernet does just fine. The top Ethernet system on the TOP500 list -- at number 58 -- is the new ATLAS cluster at the Max Planck Institute for Gravitational Physics in Germany.

New HPC White Paper: Star-P® Performance on IBM Linux Clusters

Jul 03 | | The paper explores some of the performance benefits of Star-P on commodity scalable systems such as IBM's Linux clusters based on multi-core Intel Xeon processors. The results demonstrate substantial performance gains with almost no programmer effort-roughly a 24-fold speed improvement for solving linear matrix equations. An overview of parallel computing with Star-P, a description of the performance test cases and description of IBM cluster configurations used for testing are also addressed.
