Today President Obama issued an Executive Order establishing the National Strategic Computing Initiative (NSCI) to ensure the United States continues leading high performance computing over the coming decades.

Speeding Up CFD Codes with Allinea Performance Reports

allineademo

In this video from ISC 2015, Mark O’Connor demonstrates how the Allinea Performance Reports tool enables coders to speed up hydro, a real-world CFD code. “Allinea Performance Reports are the most effective way to characterize and understand the performance of HPC application runs. One single-page HTML report elegantly answers a range of vital questions for any HPC site.”

Intelligent Light Scales CFD Code to 64,000 Cores

Today Intelligent Light announced breakthrough CFD scalability running the AVF-Leslie combustion simulation code on up to 64,000 cores on NERSC supercomputers.

Reducing Jet Noise with Large Eddy Simulations

Over at Argonne National Lab, John Spizzirri writes that GE researchers are using the Mira supercomputer to learn how noise propagates from jet propulsion and wind turbine systems. The team, lead by Umesh Paliath and Giridhar Jothiprasad, is studying the complex behavior of air as it passes through jet exhaust nozzles and over wind turbine blades.

Scaling STAR-CCM+ to 55,000 Cores on Hornet

Hornet Supercomputer

Today CD-adapco announced a significant scalability milestone for its STAR-CCM+ CFD software. Optimized over the course of a year in collaboration with HLRS and SICOS BW, STAR-CCM+ was run on the entirety of the 1.045 PetaFlop Hermit cluster, managing to maintain perfect scalability beyond 55,000 cores.

Pointwise Adds Overset Grid Assembly to CFD Meshing Software

imr-maestro-2013-300x300

Today Pointwise announced the latest release of its computational fluid dynamics (CFD) meshing software featuring direct integration with overset grid assembly (OGA) software.

Supercomputing Santa’s Intractable Task

Warp Drive

Over at the Adaptive Computing Blog, Trev Harmon takes a computational look at the Santa mythology and how a parallel machine would go about servicing the estimated 1,333,316,210 households on Planet Earth.

The Past, Present and Future of Engineering Simulation

Bill Clark, EVP at CD-adapco

“Whereas previous generations of engineers could take some comfort in the ‘safety net’ of extensive physical testing to rescue them from the occasional poor prediction, CAE is increasingly the victim of its own success as simulation continues to displace hardware testing as industry’s verification method of choice. Although this increased confidence in simulation is well-deserved (and has been hard-earned through many years of successful prediction), it brings with it a great deal of pressure to ‘get the answer right’ every time.”

Accelerating CFD with PyFr on GPUs

Flow over a spoiler deployed at 90 degrees to the oncoming flow, computed on a mesh with 1.3 billion degrees of freedom using 184 x Nvidia M2090 GPUs (Emerald HPC facility at the Centre for Innovation UK).

Over at TechEnablement, Dr. Peter Vincent writes that PyFR is an open-source 5,000 line Python based framework for solving fluid-flow problems that can exploit many-core computing hardware such as GPUs.
