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() [1/2]

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.

operator delete()

static void dueca::NetTimingLog::operator delete ( void *  p )

static

new operator "delete", to go with the new version of operator new.

operator new() [2/2]

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

inlinestatic

placement "new", needed for stl.

packData()

void dueca::NetTimingLog::packData

(

::dueca::AmorphStore &
