[Users] Cactus -- Bench_Whisky_Carpet benchmark

[Baker D.J.]

Hi all,

Hopefully this is very easy question for someone.

My knowledge of Cactus is minimal. I'm not a user of the package, however I am involved in preparing some applications for benchmarking. I've recently been testing out Bench_Whisky_Carpet since this benchmark most closely represents the type of Cactus applications that researchers at Southampton are running. On our latest Opteron (3 GHz) processors it's taking in the region of 11 minutes to complete, and my major concern is that is will complete even faster as we move to other systems (perhaps..). We have some Intel quad core machines arriving soon, and that will be an interesting test case.

My question is essentially how to "rebase" this benchmark without actually losing the essence of what it's doing. That is, is there a parameter that I can adjust to increase the number of iterations completed or whatever?

Please could some one advise me.
