Most of the parallel enabled filters are in VTK/Parallel, although ParaViewCore/VTKExtensions has quite a few also.<div>See VTK/Parallel/vtkPStreamTracer for instance.</div><div><br></div><div>MultiCore mode is useful in the case where you have computationally expensive data processing tasks. It generally doesn't help you to process larger data (that is what parallel processing on a cluster is for, where you have abundant disks and RAM available) nor does it help accelerate rendering (same augment applies for graphics cards).</div>
<div><div><div><br></div><div>For stream tracing the parallel version may or may not be faster in practice. It depends on how load imbalanced the problem is and how much interprocessor communication has to occur.</div><div>

Hi all,<div><br></div><div>After checking source code of vtkStreamTracer, I find there is no parallel implementation, right? After skimming some other filters, I feel the same way.</div><div><br></div><div>So what is Multi-Core mode for? Is it only for executing independent tasks as a server?</div>
