C-style expression processing...

[Ron Chen]

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
