Hello,
   Defined a structure starpu_perf_model_t provided its address in the
.model field of the starpu_codelet structure, i have.
Now after execution of my app, it generated the performance model
files for the codelet with metrics mentioned for the CUDA worker I
have.
But once it is created after first execution run, no matter how many
times i run my app after that, the number in the performance model
file not change.

How does one achieve the average numbers in the performacne model
files by running the app multiple times and getting the deviation and
sum metrics there?

thank you.
