Communication ISA¶

Inter-NPU collective communication, point-to-point exchange, and runtime synchronization.

	Instruction	PTO Name	Description
	TBROADCAST	pto.tbroadcast	Broadcast data from root NPU to all ranks
	TGET	pto.tget	Get data from a remote NPU
	TGET_ASYNC	pto.tget_async	Asynchronous variant of TGET
	TNOTIFY	pto.tnotify	Notify other ranks of an event
	TPUT	pto.tput	Put data to a remote NPU
	TPUT_ASYNC	pto.tput_async	Asynchronous variant of TPUT
	TREDUCE	pto.treduce	Collective reduction across all ranks
	TSCATTER	pto.tscatter	Scatter data from root NPU to all ranks
	TGATHER	pto.tgather	Gather data from all ranks to root NPU
	TTEST	pto.ttest	Test if a notification has been received
	TWAIT	pto.twait	Wait for a notification
