in the paper titled:

Optimizing Daya Movement in the PGI Accerlator Programming Model

you discuss mirror and reflected commands. It said that the mirror command is used in FORTRAN, but will never be used in ANSI C. You went on to say that the reflecy command at that time (Februray 2011) is only in FORTRAN, but will be in c by the end of the year - 2011. Is it in pgcc now?

Is the reflected iimplemented in pgcc? If it is not there will it ever be there?

What is the alternative?

Thans in advance.

Most likely not. It was supplanted by the OpenACC "present" clause which is a more flexible construct.
