URL: https://github.com/apache/incubator-mxnet/pull/8373#issuecomment-365677294
 
 
   I'm seeing that fp16 with dist_sync_device is slower than fp32 on a cluster 
of 2 p3.8x instances. (volta gpus)
   
   imagenet-benchmark-alexnet
   fp32: 215 samples/sec
   fp16: 28 samples/sec
   
   cifar10-resnet
   fp32: 760 samples/sec
   fp16: 330 samples/sec
