Detailed Description

Class which implements stop condition based on fraction of failed kernel runs.

Constructor & Destructor Documentation

FailureFraction()

ktt::FailureFraction::FailureFraction ( const double  fraction, const uint64_t  minCount = 0  )

explicit

Initializes failure fraction condition.

Parameters

fraction	Fraction of failed kernel runs before condition is fulfilled. The valid range of values is 0.0 - 1.0 corresponding to 0% - 100% of explored configurations.
minCount	The number of configurations that is always explored

Member Function Documentation

GetStatusString()

std::string ktt::FailureFraction::GetStatusString ( ) const

overridevirtual

Returns stop condition status string. Used for logging.

Returns

Stop condition status string.

Implements ktt::StopCondition.

Initialize()

void ktt::FailureFraction::Initialize ( const uint64_t  configurationsCount )

overridevirtual

Performs initialization of stop condition. Called right before the tuning process begins.

Parameters

configurationsCount

Total count of generated configurations for the tuned kernel.

Implements ktt::StopCondition.

IsFulfilled()

bool ktt::FailureFraction::IsFulfilled ( ) const

overridevirtual

Checks whether stop condition is fulfilled.

Returns

True if stop condition is fulfilled, false otherwise.

Implements ktt::StopCondition.

Update()

void ktt::FailureFraction::Update ( const KernelResult &  result )

overridevirtual

Performs update of stop condition. Called after each tested configuration.

Parameters

result

Result from the last tested configuration. See KernelResult for more information.

Implements ktt::StopCondition.
