OpenACC and Hackathons Summit 2022 Aug. 2-4

July 8, 2022 — OpenACC will hold its annual summit from Tuesday, Aug. 2 to Thursday, Aug. 4, 2022 from 7-11 am Pacific Time. It will be a digital event. The event website is here. OpenACC said this annual summit showcases leading research both accelerated by the OpenACC directives-based programming model and optimized through the […]

Clacc – Open Source OpenACC Compiler and Source Code Translation Project

By Rob Farber, contributing writer for the Exascale Computing Project Clacc is a Software Technology development effort funded by the US Exascale Computing Project (ECP) PROTEAS-TUNE project to develop production OpenACC compiler support for Clang and the LLVM Compiler Infrastructure Project (LLVM). The Clacc project page notes, “OpenACC support in Clang and LLVM will facilitate the programming of GPUs and other accelerators in DOE applications, […]

OpenACC Names ORNL’s Jack Wells President, Updates OpenACC API

Jack Wells, director of strategic planning and performance management at Oak Ridge National Laboratory, has been named president of OpenACC, a nonprofit dedicated to advancing scientists’ parallel computing skills. OpenACC also announced updates to Version 3.1 of OpenACC API for writing parallel programs in C, C++, and Fortran, and it announced the 2021 schedule of […]

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.”

OpenACC User Group at GTC San Jose

Hackathons are 5-day events designed to help teams of three to six developers accelerate their own codes on GPUs with OpenACC or other tools. Each team is assigned two mentors for the duration of 5 days to help teams port their code to GPUs or optimize its performance. No previous GPU experience required, teams are […]

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.”

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.”
