<div dir="ltr">I am not sure if anyone has tried putting Piston and Coprocessing together yet. If so I would like to hear about it. If not and someone is trying, I wouldn't mind getting involved in that effort.<div><br>
</div><div>But yes Mark you are right. As it stands there will be a round trip in between the simulation and vis stages. We will have to extend Catalyst with the ability to create a vtkPistonDataObject that refers to the data already on the GPU in order to avoid it.</div>

<p class="MsoNormal">Hello, for a CUDA application with coprocessing, is it correct that between a simulation step and coprocessing that the data will make a roundtrip from the device to the host and back to the device, since parts of the vis pipeline run on
the CPU?<u></u><u></u></p>
