OpenACC的C /预处理器标准宏？

Question

在OpenMP模式下编译时，在OpenMP中我们定义了_OPENMP宏（几乎所有我知道的编译器 - gcc，pgi，intel，...）。在OpenACC模式下编译时，我们是否有类似的“标准”宏定义（Cray / pgi /其他编译器）？

是的，您为openacc定义了类似的宏：_OPENACC。

2.2 Conditional Compilation

The _OPENACC macro name is defined to have a value yyyymm where yyyy is the year and
mm is the month designation of the version of the OpenACC directives supported by the
implementation. This macro must be defined by a compiler only when OpenACC directives
are enabled. The version described here is 201306.
