Data Structures
class	controlPointMain
	A mainchare that is used just to create our controlPointManager group at startup. More...
Typedefs
typedef enum tuningSchemeEnum	tuningScheme
Enumerations
enum	tuningSchemeEnum {   RandomSelection, SimulatedAnnealing, ExhaustiveSearch, CriticalPathAutoPrioritization,   UseBestKnownTiming, UseSteering, MemoryAware, Simplex,   DivideAndConquer, AlwaysDefaults, LDBPeriod, LDBPeriodLinear,   LDBPeriodQuadratic, LDBPeriodOptimal }
Functions
double	closestInRange (double v, double a, double b)
static void	periodicProcessControlPoints (void *ptr, double currWallTime)
	Called periodically to allow control point framework to do things periodically.
void	printTuningScheme ()
CkReductionMsg *	idleTimeReduction (int nMsg, CkReductionMsg **msgs)
	A reducer that combines idle time measurements (min/sum/max etc.).
CkReductionMsg *	allMeasuresReduction (int nMsg, CkReductionMsg **msgs)
void	registerCPReductions (void)
	Registers the control point framework's reduction handlers at startup on each PE.
unsigned int	randInt (unsigned int num, const char *name, int seed=0)
	Return an integer between 0 and num-1 inclusive If different seed, name, and random_seed values are provided, the returned values are pseudo-random.
void	gotoNextPhase ()
	An interface callable by the application.
FLINKAGE void	FTN_NAME (GOTONEXTPHASE, gotonextphase)()
void	registerCPChangeCallback (CkCallback cb, bool frameworkShouldAdvancePhase)
	An interface callable by the application.
void	setFrameworkAdvancePhase (bool frameworkShouldAdvancePhase)
	An interface callable by the application.
void	registerControlPointTiming (double time)
	An interface callable by the application.
void	controlPointTimingStamp ()
	An interface callable by the application.
FLINKAGE void	FTN_NAME (CONTROLPOINTTIMINGSTAMP, controlpointtimingstamp)()
FLINKAGE void	FTN_NAME (SETFRAMEWORKADVANCEPHASEF, setframeworkadvancephasef)
void	controlPointShutdown ()
	Shutdown the control point framework, writing data to disk if necessary.
void	controlPointInitNode ()
	A function called at startup on each node to register controlPointShutdown() to be called at CkExit().
int	controlPoint (const char *name, int lb, int ub)
	Get control point value from range of integers [lb,ub].
FLINKAGE int	FTN_NAME (CONTROLPOINT, controlpoint)(CMK_TYPEDEF_INT4 *lb
	A fortran callable one.
void	ControlPointWriteOutputToDisk ()
	Write output data to disk. Callable from user program (for example, to periodically flush to disk if program might run out of time, or NAMD).

char	CPDataFilename [512]
bool	enableCPTracing
std::map< std::string, int >	defaultControlPointValues
	The control point values to be used for the first few phases if the strategy doesn't choose to do something else.
CkReduction::reducerType	idleTimeReductionType
	A reduction type that combines idle time measurements (min/sum/max etc.).
CkReduction::reducerType	allMeasuresReductionType
	A reduction type that combines idle, overhead, and memory measurements.
