Static Graphs for Coding Productivity in OpenACC [PDF]
, 2022 The main contribution of this work is to increase the coding productivity for GPU programming by using the concept of Static Graphs. To do so, we have combined the new CUDA Graph API with the OpenACC programming model.

OmpSs-2 and OpenACC interoperation [PDF]
, 2023 We propose an interoperation mechanism to enable novel composability across pragma-based programming models. We study and propose a clear separation of duties and implement our approach by augmenting the OmpSs-2 programming model, compiler and runtime ...

Three-dimensional gravity inversion based on optimization processing from edge detection
Geodesy and Geodynamics, 2022 Gravity inversion requires much computation, and inversion results are often non-unique. The first problem is often due to the large number of grid cells.

Implementing the OpenACC Data Model
2017 IEEE International Parallel and Distributed Processing Symposium Workshops (IPDPSW), 2017 Programming accelerators today usually requires managing separate virtual and physical memories, such as allocating space in and copying data between host and device memories. The OpenACC API provides data directives and clauses to control this behavior where it is required.

Comparative Analysis of OpenACC Compilers [PDF]
, 2016 OpenACC has been on development for a few years now. The OpenACC 2.5 specification was recently made public and there are some initiatives for developing full implementations of the standard to make use of accelerator capabilities. There is much to be done yet, but currently, OpenACC for GPUs is reaching a good maturity level in various implementations

Automatic Two-level Parallel Translation Method for PMVS Algorithm [PDF]
Jisuanji gongcheng, 2022 Currently, the calculation speed of the image processing algorithm is very slow when high-resolution images are used as input data.Although parallelizing the algorithm can improve its execution efficiency, the manual conversion of serial programs to ...
