interface InferenceEngine::ExecutorManager

Overview

Interface for tasks execution manager. This is global point for getting task executor objects by string id. It’s necessary in multiple asynchronous requests for having unique executors to avoid oversubscription. E.g. There 2 task executors for CPU device: one - in FPGA, another - in OneDNN. Parallel execution both of them leads to not optimal CPU usage. More efficient to run the corresponding tasks one by one via single executor. More…

Typedefs

typedef std::shared_ptr<ExecutorManager> Ptr

A shared pointer to ExecutorManager interface

Methods

virtual ITaskExecutor::Ptr getExecutor(const std::string& id) = 0

Returns executor by unique identificator.

Parameters:

id	An unique identificator of device (Usually string representation of TargetDevice)

Returns:

A shared pointer to existing or newly ITaskExecutor

virtual void setTbbFlag(bool flag) = 0

Set TBB terminate flag.

Parameters:

flag	A boolean value: True to terminate tbb during destruction False to not terminate tbb during destruction

Returns:

void

static ExecutorManager \* getInstance()

Returns a global instance of ExecutorManager.

Returns:

The instance.
