Those that went with UNIX (and a few that were willing to change over having realized their mistake) have doubled and trebled (and, in one case 12x) their performance by replacing their hardware with newer hardware that is coming out mostly running UNIX. Some of these purchases were fully funded by sale of the used equipment, all cost 1/3 or less price of the equipment they were replacing (typically, a $250,000 mini-computer for a $65,000 super-micro which was much faster.) Two groups have specifically said that they have not taken advantage of this because their fortran code has become too heavily dependant on the vendor's proprietary hardware/software environment and they do not have the personnel resources to switch over. Don't make the same mistake, project your upgrade options for both cases in the current context (as if you made this decision two years ago.) I think the facts speak for themselves. What good is it to have a great optimizer on a slow machine? -Barry Shein, Boston University
