<p class="MsoNormal"><span style="font-size:11.0pt">I am bringing this up because it seems that OpenMP development is really ramping up now and I want to bring up a common use case that does not seem to be supported with other vendor compilers.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt">It is a common use case to call the Fortran intrinsic Math functions in an openmp target region. I am not sure how this in implemented in the Fortran + OpenMP compilers for the vendors who do support it. I
suspect this is done by inlining, but it appears that other vendors have their Fortran math functions in a backend runtime library which somehow prevents these functions from being called in an OpenMP target region.<o:p></o:p></span></p>
