Dear Carl,<br><br>I think this part is only intended for use with PGI Accelerator, and was started before OpenACC standardization - <a href="http://www.pgroup.com/lit/articles/insider/v1n3a1.htm">http://www.pgroup.com/lit/articles/insider/v1n3a1.htm</a>. OpenACC slightly differs from original PGI Accelerator - this might be the reason for failure messages. Unfortunately, with newer PGI compiler it does not seem to work either, we've recently checked and reported the issue here: <a class="moz-txt-link-freetext" href="http://www.pgroup.com/userforum/viewtopic.php?t=3100&start=10">http://www.pgroup.com/userforum/viewtopic.php?t=3100&start=10</a><br>
Might be best to check with Michael and Craig about its status, we are also very interested.<br><br>Best regards,<br>- Dima.<br><br><div class="gmail_quote">2012/9/12 Carl Ponder <span dir="ltr"><<a href="mailto:cponder@nvidia.com" target="_blank">cponder@nvidia.com</a>></span><br>

Can any of you send me a configure.wrf and a list of build
instructions that will work for this?<br>
I'm running on a Cray.<br>
Thanks,<br>
