@srowen I think GMM maybe a special case, I found than on dense input, it suffers a small regression. (Other impls like LoR/LiR will be accelerated significantly even without native-BLAS.) But when I enable OpenBLAS, this PR is about 3X faster than existing impl, 5X faster on the prediction stage (5sec -> 1sec). @xwu99 This is for GMM, I think it is similar to KMeans. I am happy if you can help reviewing this. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
