Hi Xiaojiang

do you have multiple cores? If so, you can use -openmp 4 or something to reduce the recon time even on your linux box

Freesurfer experts:

I know in my powerful Linux machine, recon-all needs about 10 hours to finish all computation. What is the possible way I can use to greatly reduce this computation time from 10 hours to, say 1-3 hours?

Is Sun Grid Engine (SGE), or GPU/CUDA, or any other technique, helpful?

Thank you! Xiaojiang
