I don't know that we have explicitly tested it on a mac, but it should.

Hi,
I have run recon-all with both -parallel enabled (including different openmp threads) and disabled and I'm not able to get processing times same as the information provided in recon-all help. The CPU used is *Dual Intel **Xeon E5-2623 v3* paired with 32GB DDR4 RAM. Is the configuration presented in recon-all help a dual cpu configuration?
Following are the runtimes I have obtained,
no parallelization : 7 hrs and 58 mins -parallel (coarse parallelization) : 4 hrs and 39 mins -parallel (fine parallelization; -openmp 8) : 4 hrs and 34 mins -parallel (fine parallelization; -openmp 14) : 4 hrs and 37 mins
Somehow varying the number of threads is having no effect in the execution time of recon-all as can been seen from the processing times. If you can explain what could be possibly going wrong here, it will help me in speeding it up further.
Thanks, Tyson _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu mailto:Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
