EPEEC Project Fosters Heterogeneous HPC Programming in Europe

The European Programming Environment for Programming Productivity of Heterogeneous Supercomputers (EPEEC) is a project that aims to combine European made tools for programming models and performance tools that could help to relieve the burden of targeting highly-heterogeneous supercomputers. It is hoped that this project will make researchers jobs easier as they can more effectively use large scale HPC systems.

Building Cloud-Based Services to Enable Earth Science Workflows across HPC Centres

In this video from FOSDEM 2020, John Hanley from ECMWF presents: Building Cloud-Based Services to Enable Earth Science Workflows across HPC Centres. Weather forecasts produced by ECMWF and environment services by the Copernicus programme act as a vital input for many downstream simulations and applications. A variety of products, such as ECMWF reanalyses and archived […]

Video: Jack Wells from ORNL on his new role as VP of OpenACC.org

Today OpenACC.org announced a newly elected vice president reflecting increased user influence within the organization. Additionally, the organization announced its 2019 Annual Meeting will be hosted by RIKEN Center for Computational Science (RIKEN R-CCS) in Japan, as well as the schedule of upcoming hackathons and bootcamps around the world.

Video: Speeding up Programs with OpenACC in GCC

Thomas Schwinge from Mentor gave this talk at FOSDEM’19. “Requiring only few changes to your existing source code, OpenACC allows for easy parallelization and code offloading to accelerators such as GPUs. We will present a short introduction of GCC and OpenACC, implementation status, examples, and performance results.”

Call For Proposals: Worldwide GPU Hackathons in 2019

ORNL has issued its Call for Proposals for a set of global GPU Hackathons in 2019. “A GPU hackathon is a 5-day coding event in which teams of developers port their applications to run on GPUs, or optimize their applications that already run on GPUs. Each team consists of three or more developers who are intimately familiar with (some part of) their application, and they work alongside two mentors with GPU programming expertise. The mentors come from universities, national laboratories, supercomputing centers, government institutions, and vendors.”

Video: How OpenACC Enables Scientists to port their codes to GPUs and Beyond

In this video SC18, Jack Wells from ORNL describes how OpenACC enables scientists to port their codes to GPUs and other HPC platforms. “OpenACC, a directive-based high-level parallel programming model, has gained rapid momentum among scientific application users – the key drivers of the specification. The user-friendly programming model has facilitated acceleration of over 130 applications including CAM, ANSYS Fluent, Gaussian, VASP, Synopsys on multiple platforms and is also seen as an entry-level programming model for the top supercomputers (Top500 list) such as Summit, Sunway Taihulight, and Piz Daint. As in previous years, this BoF invites scientists, programmers, and researchers to discuss their experiences in adopting OpenACC for scientific applications, learn about the roadmaps from implementers and the latest developments in the specification.”

Sunita Chandrasekaran Receives NSF Grant to Create Powerful Software Framework

Over at the University of Delaware, Julie Stewart writes that assistant professor Sunita Chandrasekaran has received an NSF grant to develop frameworks to adapt code for GPU supercomputers. She is working with complex patterns known as wavefronts, which are commonly found in scientific codes used in analyzing the flow of neutrons in a nuclear reactor, extracting patterns from biomedical data or predicting atmospheric patterns.

Video: Introduction to OpenACC

Vasileios Karakasis from CSCS gave this talk at the the Directive Based GPU Programming Workshop. “Directives-based programming facilitates the task of parallelizing your application by letting you focus on its parallel logic rather than on the very details and the low-level intricacies of the GPU architecture. In this course, we will introduce the OpenACC programming paradigms for the GPU. We will cover the parallel execution model and how it can be used to leverage parallelism, the memory model and how this differs from the classic CPU paradigm.”

Porting HPC Codes with Directives and OpenACC

In this video from ISC 2018, Michael Wolfe from OpenACC.org describes how scientists can port their code to accelerated computing. “OpenACC is a user-driven directive-based performance-portable parallel programming model designed for scientists and engineers interested in porting their codes to a wide-variety of heterogeneous HPC hardware platforms and architectures with significantly less programming effort than required with a low-level model.”

OpenACC Helps Scientists Port their code at the Center for Application Readiness (CARR)

In this video, Jack Wells from the Oak Ridge Leadership Computing Facility and Duncan Poole from NVIDIA describe how OpenACC enabled them to port their codes to the new Summit supercomputer. “In preparation for next-generation supercomputer Summit, the Oak Ridge Leadership Computing Facility (OLCF) selected 13 partnership projects into its Center for Accelerated Application Readiness (CAAR) program. A collaborative effort of application development teams and staff from the OLCF Scientific Computing group, CAAR is focused on redesigning, porting, and optimizing application codes for Summit’s hybrid CPU–GPU architecture.”
