Does FasterTransformer support multi-stream pipeline parallelism ?

[FlyingPotatoZ]

Hello guys:
Because there is no dependence on computation and communication, I think multi-stream pipeline parallelism can hide communication time to improve performance.
I didn't find how to configure the multi-stream feature in the code. Can anyone help? Thank you so much~
