ptrendx commented on issue #7778: float16 has no performance improvement URL: https://github.com/apache/incubator-mxnet/issues/7778#issuecomment-327687093 V100 as in Volta? Then the speed you see is quite low even on fp32, so I would say you are limited by IO here. Default number of threads for IO is 4 which is way to low to saturate 4 V100 - could you test with --data-nthreads N option (N should be 10+ for fp16 version at least). Also, if that does not solve the issue, could you test single GPU numbers? ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
