I do a reasonable amount of scientific computing, which is pretty simple from an architecture point of view, but even then you don't have some sliding scale which says this program will use X amount of memory vs take this many CPU cycles. You might be able to guess where the tradeoff is, and make estimates for how much memory is going to be required, but you may still find the amount of memory required is too much for the machine. Or that it's acceptable but as a result the program is going to take a month to run. Or that there's no acceptable compromise and you have to adapt the underlying toolkit to allow a better way of handling the problem. Or that it's just going to take those resources to run and there's no significant improvement that can be made. And at each of those steps you have to refactor what you've written, there are no sliders to drag around to do it for you. -- imalone http://ibmalone.blogspot.co.uk -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
