Pradeep, If you have a Sandy-Bridge or Ivy-Bridge based system, and it has at least eight cores, and those cores run at 3.4GHz, and you use the '-openmp 8' flag (available in v5.3) and you arrange recon-all to run the hemi stages in parallel, then recon-all completes in about 3.5 hours. In the up

Malcolm, I think it will be at least 10% faster. I messed with the Intel compiler a couple years ago, but they wanted to charge a yearly fee for its usage (mgh doesnt qualify as an academic user), so we nixed using that compiler. also, fyi, I was unable to get the AMD compiler to build the code

Pedro, I've got a run going with the Intel compilers now (I'm assuming that's what you meant?). Besides producing faster code, it will be interesting to see whether the compilers have a noticeable result on the results. Malcolm On Wednesday 18 January 2012 12:14:42 Pedro Paulo de Magalhães O

OpenMP (depending how efficiently FreeSurfer can be parallelized) would be a great benefit here. I have no idea what's causing the centos4 vs. 5 results, but it might be interesting to start collecting some performance data if enough people are interested. All the benchmark numbers I've menti

Malcolm, actually, they (IBM) are looking at openmp (to allow multiple threads to process for-loops) and SSE3 instructions (better vectorization). recon-all --help contains some timings for an AMD processor. centos4 vs. centos5 itself should not account for any speed differences, but it is true

Stephen, The 30 minute estimate for the -autorecon1 stage is no longer accurate. It got slower when we added a feature to improved the skull-strip step. The feature is to make use of an atlas to determine where skull and cerebellum might be. To use that atlas requires a registration to that atlas
