Hi all!

I'm using flash as an experimental app for hpc performance analysis. I
would like to run some strong scaling and weak scaling tests. I'm referring
to this page:
http://flash.uchicago.edu/site/flashcode/user_support/rpDoc_4p62.py. But
there are so many arguments and I don't know which are the ones I should
change. I've tried changing iGridSize, jGridSize, and kGridSize in
flash.par, but they don't make any difference in runtime.

Could anybody tell me what are the arguments related to scaling? I would
really appreciate it!

Thanks,
Yiheng Xu
