IBM to Intel FORTRAN

[tschaack]

I am porting code from a system running AIX and IBM FORTRAN to a machine running Linux and Intel FORTRAN v10. Does anyone know the Intel compiler option that is equivalent to the IBM FORTRAN -qmaxmem=-1 ?

-qmaxmem=-1 permits each optimization to take as much memory as it needs without checking for limits.


Thanks

There is no documented switch like that. Are you actually encountering a problem?

For the IA-64 compiler, the switch -override_limits may be analogous to your IBM compiler switch. You must use it carefully; for example, if you ask for -O3 when you don't need it, and the compiler gives up on optimization, setting -O2 or -O1 may be a better tactic. As Steve indicates, you would have to give more details to get a useful answer.
