Three GPU Hackathons Going Global with OpenACC

2015-GPU-Hackathons

NCSA, ORNL, and CSCS will host a series of GPU Hackathons in 2015.

“Developed by PGI, Cray, and NVIDIA, the OpenACC directives are a shared vision of how directives can simplify the programming model for accelerators, where each vendor is committed to support a common programming standard.”

Video: Intro to Compiler Directives for Accelerators

openACC

“Geoscientists need tools to allow them to rapidly develop algorithms that run fast on accelerators, while at the same time deliver portability and improve productivity. They demand a single source code, with no need to maintain multiple code paths, using a high-level approach that presents a low learning curve. OpenACC provides directives-based approaches to rapidly accelerating applications for GPUs and other parallel architectures. This talk will serve as an introduction to programming with OpenACC 2.0.”

Performance and Power Characterization of GPU-Enabled HPC Applications

“An increasing number of GPU enabled applications are available to the HPC community. The key issues are understanding the enhanced application performance and corresponding increase in power consumption due to GPUs. In most cases these depend on the CPU to GPU ratio and the way GPUs and connected to CPUs. Latest compute node designs allow flexibility to select the number of GPUs and how they are connected CPUs. This offers users a unique opportunity to select the a suitable operating point according to their application characteristics. This talk is about studying the performance vs. power tradeoff on a few common HPC applications.”

Free Test Drive: Nvidia Tesla K80 Accelerator

Bryce Mackin, Nvidia

“Over at the Nvidia Blog, Bryce Mackin writes that the company is offering a free GPU Test Drive for their new Tesla K80 accelerator. With the test drive, you can run your own application on one or more K80s or try one of the preloaded applications, including AMBER, NAMD, GROMACS and LAMMPS.”

University of Houston Installs Opuntia Cluster

cluster

The University of Houston (UH) is adding a new, state-of-the-art supercomputer to its arsenal of research tools. With 1860 compute cores, the new Opuntia cluster will be used primarily for scientific and engineering work. The acquisition of this new system marks the start of a new era of supercomputing not only for the University of […]

Video: GPU-Accelerated Analysis of Large Biomolecular Complexes
