Compiler settings for Quad core I7 chip

What are the best project settings for Fortran Composer so that I get the fasted running code for my new computer with a quad core i7 chip? My code does not have a lot of matrix operations so that parallelization is not particularly attractive. The code is, however, a heavy "number cruncher" and execution time is a real issue.

I would start with Fortran > Code Generation > Intel Processor-Specific > The processor performing the compilation (/QxHost). Optimization > Optimization > Maximize Speed plus Higher Level Optimizations could be next.

Be sure that you are building a Release configuration.

There are some additional options that may help, but be sure to run timing tests between changes so you know what you're getting. If you have any operations that can be done with MKL calls, use MKL.
