Detailed Description

An object that exists on all workers.

The controler assigns a unique "register id" to each object, and the worker uses this id to refer to the object residing on itself.

DebugCopyFrom()

void tvm::runtime::DRefObj::DebugCopyFrom ( int  worker_id, ffi::AnyView  source  )

inline

Copy from the Tensor provided to a remote worker.

Parameters

worker_id	The id of the worker to be copied to.
source	The Tensor to be copied.

DebugGetFromRemote()

ffi::Any tvm::runtime::DRefObj::DebugGetFromRemote ( int  worker_id )

inline

Get the value of a DRef from a remote worker.

Parameters

worker_id

The id of the worker to be fetched from.

Returns

The value of the register.
