Hi,

I found out that I could use -ta=nvidia,keepgpu (for the 2009 relase) to view the GPU code, but this is not mentioned in the PGI user guide 2009, only in the 2010 guide and release notes!!

can I modify that code now and recompile using it?

Thank You

Hi ghandurah,

Correct, this flag was not documented in PGI 9.0.

can I modify that code now and recompile using it?

Yes (with nvcc). However, the result will be a “.bin” file that is external to your “.out”. To run the executable, the “.bin” must be located in the same directory as the “.out”.
