Five Reasons Why you Want to Try OpenACC – Starting with “Its Free!”

OpenACC is a directive based programming model that gives C/C++ and Fortran programmers the ability to write parallel programs simply by augmenting their code with pragmas. Pragmas are advisory messages that expose optimization, parallelization, and accelerator offload opportunities to the compiler so it can generate efficient parallel code for a variety of different target architectures including AMD and NVIDIA GPUs plus ARM, x86, Intel Xeon Phi, and IBM POWER processors.

Appentra Solutions will be part of SC16 Emerging Technologies Showcase

Today Appentra Solutions announced that the company will participate in the Emerging Technologies Showcase at SC16. As an HPC startup, Appentra was selected for its Parallware technology, an LLVM-based software technology that assists in the parallelization of scientific codes with OpenMP and OpenACC. “The new Parallware Trainer is a great tool for providing support to parallel programmers on their daily work,” said Xavier Martorell, Parallel Programming Models Group Manager at Barcelona Supercomputing Center.

OpenACC Gains Momentum in 2016

The OpenACC standards group today announced several major milestones including the addition of new member, the National Supercomputing Center in Wuxi, the adoption of OpenACC by several major HPC applications, the addition of support for new target platforms and expanded implementation

Winning Posters on GPU Programming Send UW Students to SC16

Two University of Wyoming graduate students earned a trip to the SC16 conference in November by virtue of winning the poster contest at the recent Rocky Mountain Advanced Computing Consortium (RMACC) High Performance Computing Symposium. “I hope to receive good exposure to the most recent advancements in the field of high-performance computing,” Kommera says.

Register Now for GPU Mini-Hackathon at ORNL Nov. 1-3

Oak Ridge National Lab is hosting a 3-day GPU Mini-hackathon led by experts from the OLCF and Nvidia. The event takes place Nov. 1-3 in Knoxville, Tennessee. “General-purpose Graphics Processing Units (GPGPUs) potentially offer exceptionally high memory bandwidth and performance for a wide range of applications. The challenge in utilizing such accelerators has been the difficulty in programming them. This event will introduce you to GPU programming techniques.”

Tutorial: GPU Performance Nuggets

In this video from the 2016 Blue Waters Symposium, GPU Performance Nuggets – Carl Pearson and Simon Garcia De Gonzalo from the University of Illinois present: GPU Performance Nuggets. “In this talk, we introduce a pair of Nvidia performance tools available on Blue Waters. We discuss what the GPU memory hierarchy provides for your application. We then present a case study that explores if memory hierarchy optimization can go too far.”

OpenPOWER for HPC Workshop Coming to ISC 2016

Editor’s Note: The OpenPOWER European Summit has been officially postponed until later in 2016, but don’t miss the International Workshop on OpenPOWER for HPC on June 23 at ISC 2016.  The OpenPOWER Foundation was established as a non-profit consortium to give its members the ability to innovate software/hardware solutions based on the POWER architecture. About half of […]

OpenACC Building Momentum going into GTC

Today the OpenACC standards group announced a set of additional hackathons and a broad range of learning opportunities taking place during the upcoming GPU Technology Conference being held in San Jose, CA April 4-7, 2016. OpenACC is a mature and performance-portable path for developing scalable parallel programs across multi-core CPUs, GPU accelerators or many-core processors.

2016 Hackathons Seeking Team Applications

“The goal of each hackathon is for current or prospective user groups of large hybrid CPU-GPU systems to send teams of at least 3 developers along with either (1) a (potentially) scalable application that needs to be ported to GPU accelerators, or (2) an application running on accelerators which needs optimization. There will be intensive mentoring during this 5-day hands-on workshop, with the goal that the teams leave with applications running on GPUs, or at least with a clear roadmap of how to get there. Our mentors come from national laboratories, universities and vendors, and besides having extensive experience in programming with OpenACC/CUDA, many of them develop the GPU-capable compilers and help define the OpenACC standard.”

Who Will Write Next-generation Software?

In this special guest feature from Scientific Computing World, Robert Roe writes that software scalability and portability may be more important even than energy efficiency to the future of HPC. “As the HPC market searches for the optimal strategy to reach exascale, it is clear that the major roadblock to improving the performance of applications will be the scalability of software, rather than the hardware configuration – or even the energy costs associated with running the system.”
