[vtkusers] how can I use vtkSMPTools

[Sujin Philip]

Hi Jie,

Can you tell me how you are verifying that only one thread is being used? I
would also recommend that you switch to the TBB backend for SMP
(VTK_SMP_IMPLEMENTATION_TYPE=tbb) as openmp support on the vc2015 compiler
is poor. You can download Intel TBB from:
https://www.threadingbuildingblocks.org/download#stable-releases.

Thanks
Sujin
