I am currently using ifort (Intel Fortran compiler). However, in the AMD cluster (which has AMD processors), it seems that Intel parallel studio can not be installed. Therefore I decided to use gfortran (GNU Fortran compiler) instead of ifort. In ifort, my compiler flags were
ftn -heap-arrays -mcmodel=large -g -c
I want to know the similar optimization flags in the GNU compiler.
My GCC version is 4.4.7 in centos 6.6 and the rocks cluster version is 6.2.
Gfortran compiler optimization flags similar to ifort in Intel
