OpenACC Monthly Highlights: July and August 2018

  1. 1. July and August 2018 OPENACC MONTHLY HIGHLIGHTS
  2. 2. 2 WHAT IS OPENACC main() { <serial code> #pragma acc kernels { <parallel code> } } Add Simple Compiler Directive POWERFUL & PORTABLE Directives-based programming model for parallel computing Designed for performance and portability on CPUs and GPUs SIMPLE Open Specification Developed by OpenACC.org Consortium
  3. 3. 3 silica IFPEN, RMM-DIIS on P100 OPENACC GROWING MOMENTUM Wide Adoption Across Key HPC Codes ANSYS Fluent Gaussian VASP LSDalton MPAS GAMERA GTC XGC ACME FLASH COSMO Numeca OVER 100 APPS* USING OpenACC Prof. Georg Kresse Computational Materials Physics University of Vienna For VASP, OpenACC is the way forward for GPU acceleration. Performance is similar to CUDA, and OpenACC dramatically decreases GPU development and maintenance efforts. We’re excited to collaborate with NVIDIA and PGI as an early adopter of Unified Memory. VASP Top Quantum Chemistry and Material Science Code * Applications in production and development
  4. 4. 4  Blog: Using OpenACC to Port Solar Storm Modeling Code to GPUs by Ron Caplan from Predictive Science OPENACC IN THE NEWS  InsideHPC: OpenACC Helps Scientists Port their code at the Center for Application Readiness (CARR) - Interview with Jack Wells (ORNL) and Duncan Poole (OpenACC.org)  InsideHPC: Porting HPC Codes with Directives and OpenACC - interview with Michael Wolfe (OpenACC.org) Read More Read More Read More
  5. 5. 5 RESOURCES Paper: Abstractions and Directives for Adapting Wavefront Algorithms to Future Architectures We parallelize the Koch-Baker-Alcouffe (KBA) parallel-wavefront sweep algorithm in the main kernel of Minisweep (the miniapplication) using CUDA, OpenMP and OpenACC. Our OpenACC implementation running on NVIDIA’s nextgeneration Volta GPU boasts an 85.06x speedup over serial code, which is larger than CUDA’s 83.72x speedup over the same serial implementation.
