yma11 commented on issue #27546: [SPARK-30773][ML]Support NativeBlas for level-1 routines URL: https://github.com/apache/spark/pull/27546#issuecomment-595595033 > I'm okay with a hardcoded constant. We are start with a safer one, say 512, if there are concerns around environment differences. I believe 256 is a very safe threshold since based on our experiments on this value, nativeBLAS has quite obvious advantage compared with f2jBLAS(at least 1.5X in the methods), without detailed tuning on nativeBLAS. Make it configurable in mllib will provide direct and flxible help for workloads like Kmeans. With fixed threshold is also okay.
