Another reminder for myself. Compilation options for Intel Fortran and gfortran:
Intel Fortran:
Optimization: -O3
Debug: -g -traceback -check all -fpe0 -check noarg_temp_created
(see here (in English) and here (in French) for meaning)
the option -o tells the name of the produced executable
i.e. the command is something like ifort -O3 myprog.f90 -o myprog
I often use also -heap-arrays to avoid using unlimit to manipulate the stack size: see here
gfortran:
Optimization: -O3
Debug: -g -Wall -fbounds-check -fbacktrace -ffpe-trap=invalid,zero,overflow
Detailed explanations here and here (page 24-27)
I often use the option -ffree-line-length-none to allow for lines of any length
