The OpenACC specification is a document that defines the OpenACC Application Program Interface (API), which is a collection of compiler directives that specify loops and regions of code in standard C, C++ and Fortran to be offloaded from a host CPU to an attached accelerator.

Most compilers support their own directives, but also directives such as OpenACC and OpenMP, which are backed by industry groups and implemented by a range of compilers. When using …

At its core OpenACC supports offloading of both computation and data from ahost device to an accelerator device. In fact, these devices may be the same or may be completely different

This repository contains codes featured in the OpenACC Examples Document. All code in this repository was created by either the OpenACC V&V team or members of the community. We will continue to add and edit code to the guide to conform to …

We are continuously adding and editing tests to conform to the latest version of the OpenACC Specification. What we do: Revealing ambiguities in the OpenACC Specification

Introduction to OpenMP & OpenACC 11 • In parallel region, variables -- mostly -- shared by default • Except: loop indices are private by default • What is wrong with the following code segment ?

2022年3月9日 · OpenACC是CUDA的一个补充编程模型，使用基于编译器指令的API，具有高性能、可编程性和跨平台可移植性。接下来将会介绍OpenACC的概念和方法，重点介绍CUDA和OpenACC之间的关系。 OpenACC的线程模型与CUDA的线程模型类似，但添加了一个并行的维度。
