[Nek5000-users] compiler optimizations

[nek5000-users at lists.mcs.anl.gov]

Hello,

I have been playing with compiler flags and directives to see if I can
improve the time-to-solution of the turbChannel example.  I have had some
success and would like to give back to the community.  What is the best
procedure for doing this?

I'm using the Intel-13.1.3.192 compiler on a Sandybridge Xeon.

baseline timing for 1000 iterations on 8 cpu is
total time   443.08s

With a few compiler directives and optimization flags I got it down to
total time   304.52s
