[Paraview] distributed stream tracer scalability issue

[burlen]

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
