New Approaches to Energy Efficient Exascale


“As displayed at ISC’14, DEEP combines a standard InfiniBand cluster of Intel Xeon nodes, with a new, highly scalable ‘booster’ consisting of Phi co-processors and a high-performance 3D torus network from Extoll, the German interconnect company spun out of the University of Heidelberg.”

HPC Analyst Crossfire from ISC’14


In this video from ISC’14, Addison Snell from Intersect360 Research moderates the conference closing session with HPC Analyst Crossfire. Panelists include: Michael Resch (HLRS), Yoon Ho (Rolls-Royce), Jean-Marc Denis (Bull), and Brian Connors (IBM).

Interview: Designing DNA Sequences in Synthetic Biology with HPC


In a quest to design synthetic microorganisms for alternate fuel sources, Howard Salis from Penn State leveraged AWS to bring supercomputing resources to scientists. “The DNA Compiler has fundamentally changed the way that genetic engineering takes place by providing a way to quantitatively control and optimize the expression of many proteins working together, instead of performing trial-and-error DNA mutagenesis.”

OrangeFS: A Scalable, Parallel File System Whose Time Has Come

Many of the major advances in HPC have been the result of collaboration between academia and the big government labs. This has been the case with PVFS (Parallel Virtual File System) and its latest generation, the scale-out file system known as OrangeFS.

Benefits of Liquid Cooling for HPC

CoolIT Rack DCLC

In this Sponsored Post from CoolIT we explore the many benefits liquid cooling offers to HPC and data center operators. For starters liquid cooling is about 3,500 times better at storing and transferring heat than air. Direct contact liquid cooling (DCLC) uses the exceptional thermal conductivity of liquid to provide dense, concentrated cooling to targeted areas. The many benefits of liquid cooling may surprise you.

Preparing for HPC Cloud Computing

HPC Cloud

Make sure you use Cloud services that are designed for HPC applications including high-bandwidth, low-latency networking, exclusive node use, and high performance compute/storage capabilities for your application set. Develop a very flexible and quick Cloud provisioning scheme that mirrors your local systems as much as possible, and is integrated with the existing workload manager. An ideal solution is where your existing cluster can be seamlessly extended into the Cloud and managed/monitored in the same way as local clusters.

Sponsored Post: Five Reasons to Celebrate Debugging at Scale

David Lecomber

“We all have our objectives for scalability. It may mean hundreds, thousands, or millions of cores to you. But spare a thought for the software teams. We need developers and application analysts in order to scale on that new machine. Do we expect only optimization? In reality, there is a necessary step before this: debugging. What should every application developer know about debugging at scale?”

Defining HPC Cluster Success Factors

HPC Cluster Success

The true cost of operating a successful HPC cluster extends beyond the initial hardware purchase or power budget. A truly well run and efficient cluster also minimizes the amount of time, resources, and level of expertise administrators need to detect and mitigate issues within the cluster.

Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration


In this video from the OpenFabrics International Developer Workshop 2014, SETI@home co-founder Dan Werthimer presents: Petaflop Radio Astronomy Signal Processing and the CASPER Collaboration. As a bellwether for exascale, radio astronomy projects like CASPER and the SKA telescope are pushing the limits of high performance computing.

Webinar: Pushing the Performance Limit of Virtual Wind Tunnels

External aerodynamics analysis plays a key role in modern automotive design. But while performance can be tested in physical wind tunnels, doing so is extremely costly — and often numerous test runs are required to determine the changes needed to improve results. Virtual wind tunnel simulations provide an alternative by allowing design engineers to study aerodynamic loads – reducing the need for physical wind tunnel testing.
