Sun is fast!

During development in early summer 2008 a number of compiler specific issues were discovered with glam. After some development work glam should now compile and run with the following ccompilers:

  • ifort (intel)
  • gfortran (gnu)
  • g95
  • f95 (Sun)
  • pgf90 (Portland Group)

Note that g95 gives much slower performance than the others. Sun gives probably the fastest run times.
