[Insight-users] parallelization

[Dan Mueller]

Hi Mauro,

To make use of multiple cores for registration, please set the CMake variable
    ITK_USE_OPTIMIZED_REGISTRATION_METHODS = ON

This allows some interpolators/metrics to utilize multiple cores. For
full details, please see:
    http://www.insight-journal.org/browse/publication/172

Hope this helps.

Regards, Dan
