Multi-GPU implementation of a time-explicit finite volume solver using CUDA and a CUDA-Aware version of OpenMPI with application to shallow water flows [PDF]
Computer Physics Communications, 2020 This paper shows the development of a multi-GPU version of a time-explicit finite volume solver for the Shallow-Water Equations (SWE) on a multi-GPU architecture. MPI is combined with CUDA-Fortran in order to use as many GPUs as needed. The METIS library

An Early Performance Comparison of CUDA and OpenACC
MATEC Web of Conferences, 2018 This paper presents a performance comparison between CUDA and OpenACC. The performance analysis focuses on programming models and underlying compilers. In addition, we proposed a Performance Ratio of Data Sensitivity (PRoDS) metric to objectively compare

Research on the simulation of PF-LBM model based on MPI+CUDA mixed granularity parallel
AIP Advances, 2018 A microstructure numerical model is an intensive computational problem, for which the simulation time is too long and the simulation scale is too small. To solve these two problems, in this article, we use MPI+CUDA hybrid particle heterogeneous parallel ...

Performance Evaluation of Advanced Features in CUDA Unified Memory [PDF]
Workshop on Memory Centric High Performance Computing, 2019 CUDA Unified Memory improves the GPU pro- grammability and also enables GPU memory oversubscription. Recently, two advanced memory features, memory advises and asynchronous prefetch, have been introduced. In this work, we evaluate the new features on two
