'''OpenACC''' (开源加速器（ '''O'''pen '''Acc'''elerators）的简称) 是一个由[[克雷]]公司，CAPS公司，[[輝达]]公司和[[The Portland Group|PGI]]公司共同开发的[[平行處理]]程式設計标准。设计这个标准的初衷是为了简化[[异构计算]]（[[中央处理单元|CPU]]/[[图形处理单元|GPU]]）系统的平行程式設計。<ref>{{cite web|url=http://www.theinquirer.net/inquirer/news/2124878/nvidia-cray-pgi-caps-launch-openacc-programming-standard-parallel-computing|title=Nvidia, Cray, PGI, and CAPS launch ‘OpenACC’ programming standard for parallel computing|date=4 November 2011|website=The Inquirer|accessdate=2016-12-05|archive-date=2016-12-25|archive-url=https://web.archive.org/web/20161225024728/http://www.theinquirer.net/inquirer/news/2124878/nvidia-cray-pgi-caps-launch-openacc-programming-standard-parallel-computing|dead-url=no}}</ref><br />
<br />
正如在[[OpenMP]]中那样，程式設計師可以通过在[[C语言|C]]、[[C++]]和[[Fortran]] [[源代码]]中添加注释以指明哪些代码段需要使用[[编译指令]]或其他函数加速。<ref name=OpenACC20>{{cite web|url=http://www.openacc.org/sites/default/files/OpenACC%202%200.pdf|title=OpenACC standard version 2.0|website=OpenACC.org|accessdate=14 January 2014|archive-date=2016-08-03|archive-url=https://web.archive.org/web/20160803144934/http://www.openacc.org/sites/default/files/OpenACC%202%200.pdf|dead-url=no}}</ref> 与OpenMP 4.0或其更新的版本类似，OpenACC的代码既可以在[[中央处理器|CPU]]上启动，也可以在[[图形处理器|GPU]]上启动。<br />
