reflect_init and reflect_do in Fortran

[Noriyuki Kushida]

Dear all,

I have a quick question;

Are reflect_init and reflect_do in Fortran, particularly for ACC, implemented?

Xmpf90 seems cannot recognize the directive.

In my environment, the reflect directive takes very long for GPU arrays, and I am looking for a way to speed up.

Best regards,

Noriyuki

I am very sorry, but I missed one thing I should tell;

As far as I see, there are many cudaHostRegister and cudaHostUnregister calls that are likely to be associated to "reflect", according to NVVP.

For this reason, I wanted to try reflect_init/do.

Best regards,

Noriyuki

Dear Noriyuki,

We are really sorry, but reflect_init/do are not supported in XACC/Fortran.

Best regards,
