Sorry about that.
The default options are nearly optimal, and the difference between a
modern (4.4 or 4.5) series GCC and the Intel compilers are only a
couple of percent. Just be sure to have FFTW available.

faster than FFTW3, last I tested, but much more fiddly to link.

Dear Users:
We recently received our new computer. This computer have 4 multicore
Opteron AMD cpus and I am planning to install GROMAS. Which options I will
need to use in order to achieve the best possible performance?
Which compiler GNU or Intel?
Thank you for all you help.
Anthony
