By the way, did you make sure to apply D3? disk_out_ref.ex2 is not
partitioned so by default it would be loaded entirely onto MPI rank 0.

Hello,
I have a question related to the parallelism of the stream tracer: As I
understand the code right, each line integration (trace) is processed in an
own MPI process. Right?
To test the scalability of the Stream tracer I've load a structured
(curvilinear) grid and applied the filter with a
Hi Stephan,
The parallel stream tracer uses the partitioning of the grid to determine
which process does the integration. When the streamline exits the subdomain
of a process there is a search to see if it enters a subdomain assigned to
any other processes before figuring it whether it has left
Hi, Stephan,
The previous implementation only has serial performance: It traces the
streamlines one at a time and never starts a new streamline until the
previous one finishes. With communication overhead, it is not surprising
it got slower.
