Generating present_or_copy(r[0:][0:])
It appears that r is being copied to the device so I'm not sure why this would occur. Maybe the working set of r is smaller than the actual size so it's not being mapped correctly? Try setting the full extent of both dimensions.

Could r be a ragged array or not contiguous in memory?

Mex function+PGI compilers work and perform well. It is time that Mathworks supports PGI compilers.
The folks at MathWorks are very open to supporting PGI, and I have contacts there. I unfortunately haven't had time to push them on it. Please do contact them with you experience since having a user push goes further than a vendor.
