haojin2 edited a comment on issue #11795: [WIP] Fix problematic backward of take & embedding URL: https://github.com/apache/incubator-mxnet/pull/11795#issuecomment-405821117 @leezu I'm encountering some unit test problems in this and will debug that a bit. The benchmarks were on a single K80 on my dev machine, I'll also do a benchmark on a p3 tmr. Regarding the original kernels, I'll run a check on whether they are still used elsewhere or we may even need to bring them back if we observe a severe performance regression on V100, I'll keep it for now and marking this PR as WIP. Will let you know once I've got the latest results. Thanks for your quick reply!
