There was a problem hiding this comment.
另外再测一组 optimize_cast + fp16_allreduce + fuse_grad_merge 吧

还有优化空间，grad和param按dtype分类之后再fuse，可以减少coalesce op个数以及fused var的个数。下一个pr可以继续优化。 |

Describe
Fused gradient merge under pipeline mode
The following test are using Ernie 3.0 model on 8 V100 GPUs, with PP=2, MP=2 and DP=2
Throughput compared tokens/s (increase compared with baseline)
Loss compared between baseline and fp16 allreduce
Loss compared between baseline and grad fuse
Loss compared between baseline and fp16 allreduce with grad fuse
Loss compared between baseline and fp16 allreduce, optimizer cast with grad fuse
