Creating Optimized External Aerodynamics with Virtual Wind Tunnels

virtual wind tunnel

Altair’s HyperWorks Virtual Wind Tunnel running on Cray XC30 or CS300 systems, can now predict a vehicle’s external aerodynamic performance and improve the cooling, comfort, visibility and stability features in their designs — without the need for numerous physical wind tunnel tests.

Slidecast: New PGI 2014 Release Adds OpenACC 2.0 Features and x64 Performance Gains

Doug Miles

In this slidecast, Doug Miles from Nvidia describes the new features and performance gains in the PGI 2014 release. “The use of accelerators in high performance computing is now mainstream,” said Douglas Miles, director of PGI Software at Nvidia. “With PGI 2014, we are taking another big step toward our goal of providing platform-independent, multi-core and accelerator programming tools that deliver outstanding performance on multiple platforms without the need for extensive, device-specific tuning.”

How New Features in CUDA 6 Make GPU Acceleration Easier


Mark Harris from Nvidia presents this talk from SC13. “The performance and efficiency of CUDA, combined with a thriving ecosystem of programming languages, libraries, tools, training, and services, have helped make GPU computing a leading HPC technology. Learn how powerful new features in CUDA 6 make GPU computing easier than ever, helping you accelerate more of your application with much less code.”

Online Tutorial: Hybrid MPI and OpenMP Parallel Programming

openmp has posted the slides and audio from a day-long tutorial on Hybrid MPI and OpenMP Parallel Programming from SC13.

The University of Luxembourg is harnessing the power of Allinea MAP in its quest to speed up research and to be among the world’s top universities.

A Software Rosetta Stone for Supercomputing

Over at ZDnet, Nick Heath writes that a group of researchers from three UK universities are attempting to create a software Rosetta Stone. In such a system, the compiler decides for itself which hardware device is best suited to run a particular block of code.

We are posed with a very complex problem of program transformation if we want to tackle these heterogeneous systems and we can’t afford, one, to do the transformations manually, and, two, to be wrong,” said Dr Wim Vanderbauwhede of the University of Glasgow.

Programming Nvidia GPUs with OpenACC Directives


In this video from the Nvidia booth at SC13, Michael Wolfe presents on OpenACC. “The OpenACC API provides a high-level, performance portable programming mechanism for parallel programming accelerated nodes. Learn about the latest additions to the OpenACC specification, and see the PGI Accelerator compilers in action targeting the fastest NVIDIA GPUs.”

Ruud van der Pas Presents: OpenMP Tasking Explained


In this video from SC13, Ruud van der Pas from Oracle presents an overview of tasking in OpenMP 4.0.

A Gentle Introduction to MPI


PRACE has developed an extensive series of online HPC Tutorials. In this video, CSC provides a basic introduction to parallel programming concepts such as task/data parallelism and an introduction to parallel programming concepts such as parallel scaling and Amdahl’s law.
