Hi Zp,
Thanks for the hint, I hadn't expected that, and was using rk4.

Hi Burlen:
Have you tried the RK-45 integrator? It uses an adaptive step size
and hence in many cases makes streamline integration faster than the
other two modes (RK-2 and RK-4)? I agree with John in that the low
performance exhibited to us might be caused by 'other' (data-depenent)
components than the inherent integration part itself, e.g., point
location and cell location in an unstructured grid (which are cetainly
also related to streamline integration).
Thanks.

We've been using the distributed stream tracer to generate
100s-1000s of stream lines per time step. It's very slow, and it
doesn't scale at all. The class comments say as much. I'm sure
there is a reason why this implementation was chosen. Is there
something that generally prevents real parallel implementation? Is
there a better implementation available out there?
There is this post a while back

What's the status?
Thanks
