    Hi All,

    Iam using OPL 6.1 in windows xp on my pc.

    I have close to 100 scenarios in my mathematical model which Iam simulating in the OPL Model and generating a solution.
    I am getting out of memory. Hence I would like to try parallel computing or if it solves the memory issues, use a super computer([b]which runs on linux[/b]) . Can anyone here share the knowledge on  how to make such a move with minimal changes to my model code.

    Thanks in advance.

    Cheers,
    Tushar.

    Hello,
    well, as far as I can see there is no good news :-(

    if you "need" more memory I can't really see how parallel stuff could solve that problem... I guess either you need to have more physical memory or you have to decompose your model into smaller pieces which can be solved independently, therefore sequentially (with less memory need).

    although OPL's oplrun is available on linux OPL doesn't run in any form on supercomputer (linux)...

    cheers
