[Insight-users] Multi-threaded Image Registration Examples?

[Oleksandr Dzyubak]

Hi Luis,

I finally got money to upgrade my Linux box and soon I'll build
a 4 CPU station with 16 GB memory.

Quick question.
For my work I mostly use smoothing/denoising, segmentation, and 
morphology filters.
And now I want to benefit from my new 4 CPU station.
How can I activate the multi CPU (multi threading) support when using ITK?

Thanks,
Alex
