    Hi,

    I am trying to add a new feature in Gridengine
    (free/opensource) to support ex-LSF users - there are
    more and more LSF users migrating to Gridengine), and
    some requested this one:

    In LSF, a user can specify from the command line the
    resource requirements of a batch job:

     (mem >= 100 || pg < 200.0)

    Where mem and pg are variables (they changes in time,
    and the master cluster scheduler has the most
    up-to-date information). And what I need is to find
    out whether the expression is true or not.

    My question is, is there an expression processing
    library that can handle complex equations easily?

     -Ron
