Static Public Member Functions
static void *	operator new (size_t size)

static void *	operator new (size_t size, void *mem)
	accompanying placement operator "new"
static void	operator delete (void *p)
	new operator "delete", to go with the new version of operator new.
static void *	operator new (size_t size, NetTimingLog *&o)
	placement "new", needed for stl.
static void	printhead (std::ostream &os, const std::string &label)
	Print a header to a file.

Public Attributes

Static Public Attributes
static const char *const	classname
	The name of this class.
static const uint32_t	magic_check_number
	a "magic" number, hashed out of the class definition, that will be used to check consistency of the sent objects across the dueca nodes.

Detailed Description

Timing information on network use.

This provides a histogram view of the network communication time cycle. Timing is logged for a number of cycles, giving a histogram of times

Member Function Documentation

operator new()

static void * dueca::NetTimingLog::operator new ( size_t size )

static

new operator "new", which places objects not on a heap, but in one of the memory arenas.

This to speed up memory management.

packDataDiff()

void dueca::NetTimingLog::packDataDiff	(	::dueca::AmorphStore &	s,
		const NetTimingLog &	ref ) const

packs the NetTimingLog into amorphous storage.

only differences with a previous object are packed.

histoLog()

void dueca::NetTimingLog::histoLog	(	unsigned	meastime,
		unsigned	cycletime )

Enter a datapoint in the histogram log.

Parameters

meastime	Measured time
cycletime	Cycle time

histTime()

float dueca::NetTimingLog::histTime

(

unsigned

idx

)

const

fraction of regular timing

Parameters

idx	Histogram bin selection
