what's the different with these three options

Dear Mat,

When I need set the Enable OpenACC Directives, there will be three options for Yes: -acc,-acc=strict,-acc=verystrict.

What’s the different with these 3 options?

I’m looking forward your reply


Hi teslalady,

“-acc” enables the OpenACC directives but also accepts the PGI Accelerator directives and other PGI extensions. “-acc=strict” will issue a warning, while “-acc=verystrict” will stop compilation, if the compiler finds any non-OpenACC directives or extensions.
