| |
| <p>The OpenACC Fortran runtime library routines are provided both in a |
| form of a Fortran 90 module, named <code>OPENACC</code>, and in form of a |
| Fortran <code>include</code> file named <samp>openacc_lib.h</samp>. The |
| procedures provided by <code>OPENACC</code> can be found in the |
| <a href="http://gcc.gnu.org/onlinedocs/libgomp/index.html#Top">Introduction</a> in <cite>GNU Offloading and Multi Processing |
| Runtime Library</cite> manual, the named constants defined in the modules |
| are listed below. |
| </p> |
| <p>For details refer to the actual |
| <a href="http://www.openacc.org/">OpenACC Application Programming Interface v2.0</a>. |
| </p> |
| <p><code>OPENACC</code> provides the scalar default-integer |
| named constant <code>openacc_version</code> with a value of the form |
| <var>yyyymm</var>, where <code>yyyy</code> is the year and <var>mm</var> the month |
| of the OpenACC version; for OpenACC v2.0 the value is <code>201306</code>. |
