[Paraview-developers] Catalyst: Saving memory with no-copy adapters

[David Lonie]

Hi folks,

ParaView is being used for live analysis and visualization of running
simulations though the Catalyst coprocessing library, and until now it was
necessary to copy the simulation dataset into a VTK container so that it
could be used in a pipeline. This essentially doubled the memory
requirements for the dataset when coprocessing is used.

New work in VTK allows external memory to be used with a VTK dataset
interface. The new classes and methods that make this possible are
described on the Kitware blog:

and detailed on the VTK wiki:

Happy computing!
Dave
