Yes. However, it's not always 30%, this is the maximum we observed.
Is that FORTRAN code?
It's C and Fortran code.
Anyway, what I need to optimize for my Core 2 Duo system is Java doing long-running symbolic (non-numeric) algorithms. I'm going to be adding concurrent processing to the system soon, now that multi-core processors are becoming common. Fortunately, many of the problems it runs are amenable to this kind of optimization on multi-core or multi-processor systems because it decomposes many problems into independently solvable sub-problems.
I use MPI or OpenMP to parallelize processing on the cluster or one cluster node with multiple CPUs, respectively. I have no experience with Java doing algorithmic work.
