[Omp] Automated tuning of omp pragmas?

[Christian Convey]

I've noticed that OpenMP offers a number of pragmas with tunable
parameters such as chunk-size.  I imagine that in a program with many
OpenMP sections, this presents a very large tuning space.

Has anyone looked at using an automated method (i.e. a stochastic
search) to search through the tuning space to look for values that
perform well on a given target system?

Thanks,
Christian
