Hi Alexey,
Parameter arrays get initialized on the device so don't need be copied. You should have seen a warning during compilation:
| Quote: | | PGF90-W-0155-Constant or Parameter used in data clause - |
I think what you might be seeing is the section descriptions for the arrays being copied over. The arrays themselves should already be on the device.
It's a a lot of output, but you can set the environment variable "PGI_ACC_DEBUG=1" to see every device call. It might shed some light what variables are being copied.

Hi Mat,
I don't see this warning. I use
| Code: | $ pgfortran -V
pgfortran 13.2-0 32-bit target on x86 Linux -tp nehalem

Do you have the "-w" flag on your compile line? "-w" disables warning messages so could be why you don't see it. Otherwise, I'm not sure and will need a reproducing example to better understand what's going on.

Hi Mat!
You are right, I have "-w" option. Thank you. |
