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.

Paper: OpenACC performance for simulating 2D radial dambreak using FVM HLLE flux
By P H Gunawan and M R Pahlevi
“The aim of this paper is to investigate the performances of openACC platform for computing 2D radial dambreak. Here,
the shallow water equation will be used to describe and simulate 2D radial dambreak with finite volume method (FVM)
using HLLE flux...The results show the using OpenACC, the computational time is reduced. For the dry and wet radial
dambreak simulations using 2048 grids, the computational time of parallel is obtained 575.984 s and 584.830 s
respectively for both simulations. These results show the successful of OpenACC when they are compared with the
serial time of dry and wet radial dambreak simulations which are collected 28047.500 s and 29269.40 s respectively.”
