SUGGESTED Compiler Options for Fortran , C and C++

  Note: 
   -ipo means to perform inter-procedural analysis across
        multiple files, and to inline subroutines and functions if possible.
   -g means to include symbol table and line-number information
        for use by a debugging program such as ddt, ddd or gdb
   -C (Fortran only) means to provide run-time checks for:
        nil pointer/allocatable array refs
        out-of-bounds array subscript/sub-string refs
        consistent shape of intrinsic  procedure array args
        uninitialized variables
        formal/actual parameter correspondence

        

Fortran:
  High Optimization: (Fastest execution)
    Use f90 -O3 -ipo program.f90

  Run-time Debugging:
    Use f90 -g -C program.f90


C: 
  High Optimization: (Fastest execution)
    Use cc -O3 -ipo program.c   

  Run-time Debugging:
    Use cc -g  program.c   


C++: 
  High Optimization: (Fastest execution)
    Use CC -O3 -ipo program.cc

  Run-time Debugging:
    Use CC -g  program.cc
