Foil 14 Hints for Using Fortran 90/95

From DoD HPF Training -- 2. Fortran90 DoD Training and Others -- 1995-98. by Chuck Koelbel -- Rice University
Declare arrays to be the natural size and shape
  • ALLOCATE in main routine (or when size is set)
  • Automatic local arrays
  • Assumed shape dummies (controversial)
Array operations are great for data parallelism
  • But they don't cover everythingŠ
Use MODULE and INTERFACE
  • Consistency checking for you
  • Extra information for the compiler
Complicated data structures are possible
  • Unclear what compilers will optimize well
