Hi THX 1138,
The compute intensity is shown when the “-Minfo=ccff,intensity” flag is used. Keep in mind though, for loops with dynamic sizes (i.e the loop bounds aren’t known until runtime), the intensity shown may be symbolic. For these cases, you need to add profile-guided feedback.
To use PFO, first add “-Mpfi” to your compilation flags and then run your code using a representative data set. “-Mpfi” instruments your code used to generate profile information. Next, recompile your code with “-Mpfo -Minfo=ccff,intensity” to view the intensity.
Note that some intensity information may still be symbolic. In these cases, the loops were most like not executed during runtime.
Hope this helps,
