I agree with Mike.<br><br>A good MPI implementation can run parallel VTK (and ParaView)<br>efficiently on SMP machines.<br>It is true that a native multithreaded application would be more<br>efficient. I have heard rumours of at least two groups who are trying<br>to address the issue.<br><br>You should also know the VTK does have some thread level parallelism<br>built in, mostly inside the Imaging filters, where the technique<br>frequently returns maximum benefits more or less trivially.<br><br>David E DeMarle<br>Kitware, Inc.<br>R&D Engineer<br>28 Corporate Drive<br>Clifton Park, NY 12065-8662<br>Phone: 518-371-3971 x109<br><br><br><br>On Tue, Jun 30, 2009 at 10:13 PM, Michael<br>Jackson<<a ymailto="mailto:mike.jackson@bluequartz.net" href="mailto:mike.jackson@bluequartz.net">mike.jackson@bluequartz.net</a>> wrote:<br>> MPI is your friend on this.<br>><br>> _________________________________________________________<br>> Mike Jackson
