Georgia Tech wins DARPA ADATA Research Funding

Search Results for: hpc

A team at the Georgia Institute of Technology has received a $2.7 million award from the Defense Advanced Research Projects Agency (DARPA) to develop technology to help address the challenges of Big Data – data sets that are both massive and complex.

The contract is part of DARPA’s XDATA program, a four-year research effort to develop computational techniques and open-source software tools for processing and analysing data, motivated by defence needs. Georgia Tech was selected to perform research in the area of scalable analytics and data-processing technology.

The team will focus on producing new machine-learning approaches capable of analyzing very large-scale data. Team members will also pursue development of distributed computing methods that can process data-analytics algorithms very rapidly with a variety of systems, including supercomputers, parallel-processing environments and networked, distributed computing systems.

‘This award allows us to build on the foundations we’ve already established in large-scale data analytics and visualisation,’ said Richard Fujimoto, leader of the Georgia Tech team. ‘The algorithms, tools and other technologies that we develop will all be open source, to allow them to be customised to address new problems arising in defence and other applications.’

The award is part of a $200 million multi-agency federal initiative for big-data research and development. It aims to improve the ability to extract knowledge and insights from the nation’s fast-growing volumes of digital data.

Slurm Workload Manager Built for Speed

Search Results for: hpc

Based on the most recent release of the Top500 List, Slurm Workload Manager continues to be the most widely used on the fastest of the fast: 33 per cent of the top 15 supercomputers use the product.

Slurm, an open-source workload manager designed for the most demanding HPC environments, originated at Lawrence Livermore National Laboratory (LLNL) 10 years ago and has evolved over time with the contributions of more than 100 developers. It remains an important workload manager at LLNL, providing scheduling and other functionality to their Sequoia supercomputer, currently number two in the Top500 and ranked the fastest in the previous Top500 List.

The other supercomputers in the 15 fastest supercomputers using Slurm are Stampede at TACC; Tianhe-1A in China; Curie at the CEA in France; and Helios at Japan’s International Fusion Energy Research Centre. Beyond the top 15 systems, SchedMD, the organisation overseeing the code base for Slurm, estimates that as many as 30 per cent of the supercomputers in the Top500 list are using the open-source workload manager.

We built Slurm to schedule efficiently resources for the world’s biggest systems and, through simulation, have proven its scalability to an order of magnitude higher than the currently largest systems,” said Moe Jette, CTO of SchedMD. “It’s now one of the most widely used workload managers in the Top500. As we move to Exascale computing requirements, Slurm is the workload manager best positioned to schedule jobs at that scale.”

Outside of the large supercomputer centres, Slurm is gathering momentum. HPC computer manufacturers Bull and Cray frequently provide Slurm as part of their solutions, and Bright Computing now offers Slurm as the default workload manager in Bright Cluster Manager.

Thought Leaders on What’s in Store for HPC in 2013?

Search Results for: hpc


Clipped from http://www.isgtw.org/feature/big-2013-find-out-what-experts-say

Over at International Science Grid This Week, Andrew Purcell catches up with HPC thought leaders from around the globe to get their take on what’s in store for 2013.

Jeff Hollingsworth, general chair of this year’s SC12 conference, also sees power efficiency as a major issue for high-performance computing: “In 2013, we will start to see serious developments in the areas of rethinking power and energy utilization for HPC. In particular, we will see new software models to help programmers better deal with dark silicon, true costs of data motion, and software-based resiliency.” Also, with large GPU-enhanced machines, such as Blue Waters and Titan now up and running, 2013 could be a “critical year” for this technology too, he argues.

Marc Hamilton’s Top 10 HPC Events That Mattered In 2012

Search Results for: hpc

HP’s Marc Hamilton is out with his list of Top Ten Events in HPC for 2012. And while he rates the launches of Intel Xeon Phi and Nvidia Kepler as #1 and #2, the revival of Lustre at #6 looks to me to be the one that will have the most lasting impact.

The 2010 Lustre User Group was held in a beautiful setting at the Seascape Resort in Monterey Bay, California but most attendees left talking not about the resort but about the changes unfolding with Lustre’s new owner. As Oracle mostly abandoned Lustre, many long-time users wondered what would happen to the open source parallel file system originally developed by Peter Braam and team at Cluster File Systems which was later acquired by Sun Microsystems and ultimately Oracle. Oracle’s disinterest in Lustre proved to be one of the best things that ever happened to it. From new companies like Whamcloud formed to offer commercial support (Intel acquired Whamcloud and formed their new High Performance Data Division in 2012) to established storage companies like Xyratex introducing new products like Clusterstor based on Lustre, the Lustre ecosystem is more dynamic and vibrant than ever. Because of its mix of use in commercial storage solutions from Xyratex, DDN, and others to its broad open source base across untold number of storage platforms, it is hard to get good statistics on Lustre use but it is hard to believe that the numbers won’t go anywhere but up in 2013, especially with its new backing from Intel’s High Performance Data Division.

Bull to Deliver Petaflop Liquid-cooled Super to Dresden University of Technology

Search Results for: hpc

French Supercomputer vendor Bull has signed a €15 Million deal with Dresden University of Technology for a petaflop supercomputer using innovative liquid cooling.

The Direct Liquid Cooling (DLC) technology developed by Bull is implemented in the new bullx supercomputer. With DLC, the HPC blades can be cooled with warm water, by evacuating the heat generated by the main components as close as possible to the source of heat, i.e. the processors and memory. With this market-leading technology, the compute blades are much more energy-efficient than standard HPC blades,” said Thomas Weselowski, Director of Extreme Computing at Bull Germany.

New Technical Report: Energy Rooflines

Search Results for: hpc

Over at Georgia Tech’s HPC Garage, Rich Vuduc writes that a new technical report presents a thought-experiment on the question of whether engineering an algorithm to optimize time differs from doing so with respect to energy Joules.

Our goal is to explain—in simple, analytic terms accessible to algorithm designers and performance tuners—how the time, energy, and power to execute an algorithm relate. The model considers an algorithm in terms of operations, concurrency, and memory traffic; and a machine in terms of the time and energy costs per operation or per word of communica- tion. We confirm the basic form of the model experimentally. From this model, we suggest under what conditions we ought to expect an algorithmic time-energy trade-off, and show how algorithm properties may help inform power management.

IBM Replaces LoadLeveler with Platform LSF on x86 Clusters

Search Results for: hpc

Over at The Register, Timothy Prickett Morgan writes that is mothballing its own LoadLeveler workload manager for x86 clusters in favor of Platform LSF, which the company acquired a little more than a year ago.

In other HPC software news, IBM has announced that it is going to put all of its weight behind the Platform LSF workload scheduler on x86-based clusters and withdraw its own Tivoli-branded LoadLeveler program for x86-based machines. IBM will sell LoadLeveler for x86-based machines until March 15 of next year and support the software until April 30, 2015. The LoadLeveler V5 for both AIX and Linux on Power will continue to be sold and supported on Power Systems servers and the variant for the BlueGene/Q will also still be available, too. That said, IBM is telling customers that Platform LSF is the workload scheduler of choice for its System x, PureFlex, and Power Systems clusters and grids, so take that into consideration when you are planning.

In related news, Morgan writes that Red Hat Enterprise Linux 6 is IBM’s Linux of choice for its massively parallel BlueGene/Q supercomputers and the Power 775 machines. Read the Full Story.

Video: Unwanted Encanto Super to be Split Between Three New Mexico Universities

Search Results for: hpc

In this video, KRQE reports that the controversial Encanto supercomputer may be split up among New Mexico’s three research universities. Purchased in 2008 for $11 Million, the supercomputer did not bring new business to the state as promised and racked up a stack of unpayed bills. The host datacenter for the system is owned by Intel and has been targeted for demolition.

Editor’s note: John West, former owner of insideHPC called the Encanto business model into question as far back as 2008.
