I was wondering if anyone can suggest the compiler options to use with OpenFOAM-2.1.1 to squeeze out the maximum performance on a HPC. The HPC has Intel Xeon CPU E5-2670.

My initial tests showed the one compiled with gcc was slightly faster when using the MotorBike Tute with simpleFoam.
Anyone have anything to share with regards to compiler performance with -O2/-O3 with gcc and/or intel or any other options (eg AVX)?
