Constructor & Destructor Documentation

Config()

InferenceEngine::IStreamsExecutor::Config::Config ( std::string  name = "StreamsExecutor", int  streams = 1, int  threadsPerStream = 0, ThreadBindingType  threadBindingType = ThreadBindingType::NONE, int  threadBindingStep = 1, int  threadBindingOffset = 0, int  threads = 0, PreferredCoreType  threadPreferredCoreType = PreferredCoreType::ANY  )

inline

A constructor with arguments.

Parameters

[in]	name	The executor name
[in]	streams	Number of streams.
[in]	threadsPerStream	Number of threads per stream that executes ie_parallel calls.
[in]	threadBindingType	Thread binding to hardware resource type. No binding by default.
[in]	threadBindingStep	In case of CORES binding offset type thread binded to cores with defined step.
[in]	threadBindingOffset	In case of CORES binding offset type thread binded to cores starting from offset.

Member Function Documentation

GetConfig()

Parameter InferenceEngine::IStreamsExecutor::Config::GetConfig

(

const std::string &

key

)

Return configuration value.

Parameters

key	configuration key

Returns

configuration value wrapped into Parameter

MakeDefaultMultiThreaded()

static Config InferenceEngine::IStreamsExecutor::Config::MakeDefaultMultiThreaded ( const Config &  initial, const bool  fp_intesive = true  )

static

Create appropriate multithreaded configuration filing unconfigured values from initial configuration using hardware properties.

Parameters

initial	Inital configuration
fp_intesive	additional hint for the the (Hybrid) core-types selection logic whether the executor should be configured for floating point intensive work (as opposite to int8 intensive)

Returns

configured values

SetConfig()

void InferenceEngine::IStreamsExecutor::Config::SetConfig	(	const std::string &	key,
		const std::string &	value
	)

Parses configuration key/value pair.

Parameters

key	configuration key
value	configuration values

SupportedKeys()

std::vector<std::string> InferenceEngine::IStreamsExecutor::Config::SupportedKeys

(

)

Supported Configuration keys.

Returns

vector of supported configuration keys
