Function Documentation

void print_memory_line ( const char * )

Print a line of memory information to pout() with a string label

void print_memory_line ( void )

Print a line of memory information to pout()

void getPeakMemoryFromOS	(	Real &	VmPeak,
		Real &	VmHWM
	)

If Linux, uses /proc/self/status to find the peak residentSetSize of process and the peak VM size. Units should be MB. Returns 0 if not Linux.

void getMemoryUsageFromOS	(	Real &	residentSetSize,
		Real &	size
	)

Return the residentSetSize of process from either /proc/self/statm or getrusage(RUSAGE_SELF, &rus) Units should be MB. If /proc/self/statm is used (Linux only), then VM size is also returned.

Real get_memory_usage_from_OS ( void )

Maintain backward compatibility in code. Return the residentSetSize of process from either /proc/self/statm or getrusage(RUSAGE_SELF, &rus) Units should be MB.

void getMemoryUsageSize	(	unsigned int &	residentSize,
		unsigned int &	size
