Intel Fortran Options

This seems to be a better option string for the Intel Fortran compiler mentioned previously:

ifort -ccdefault list -tpp7 -W0

where -ccdefault list means ignore old-fashioned Fortran carriage controls in column 1 -tpp7 means optimize for Pentium IV, which seems to include the Celeron (-tpp6 for Pentium III). According to man ifort, -tpp7 is the default. -W0 means ignore warning messages, which tend to be noting that certain features of F77 have been depreciated in F90 and F95.

Changes added in proof: I decided that the Celeron is a P-IV class machine, so I changed the processor optimization flag.
