[MINC-users] CPU Speed

[Pierre Bellec]

Very nice benchmark Andrew! As Alex said, the number of threads has
increased quite a bit in addition to pure single-thread speed, which is
hard to factor in a benchmark. Looks like GPUs are the way to reduce
dramatically computations for single datasets, e.g. BROCCOLI
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3953750/ "non-linear spatial
normalization to a 1 mm3 brain template in 4–6 s" Not sure this includes
I/O though.

Best,

Pierre
