Hi guys,

I see there are some descriptions about device side network in ncclNet

connect and accept can receive an optional netDevComm pointer from the caller, if the caller wishes to make use of device networking. This parameter may be ignored by the plugin if it does not support device-side networking.

So what is the using scenario of device network offload? is this like Gaudi that has RoCE nics in chip?

and what is the control flow supposed to be? Is netDevComm used in device side or host side?

Thanks!
