[gmx-users] How to enable fortran inner loops in Itanium 2

Dear gmx-users,

I have read the following in the website of gromacs. Recently I want to compile the gromacs code in our Itanium 2(1.G) cluster, but I find that the efficient is less than the Petiume 4 cpu(2.8G). I think if I can enable the fortran inner loops, It may be fast than the Petiume 4 right? Can anyone tell me how to enable it?

Thank you.

The Itanium doesn't have assembly inner loops, but we used fortran inner loops (that requires some tweaking and is not enabled by default since the intel compiler linking stage is quite buggy) with version 5.0.1 of the Intel C and Fortran compiler	

Sincerely yours
