print_memory_line() [1/2]

void print_memory_line

(

const char *

)

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

Referenced by PetscSolver< LevelData< FArrayBox > >::create_mat_vec(), and PetscSolver< LevelData< FArrayBox > >::setup_solver().

print_memory_line() [2/2]

void print_memory_line

(

void

)

Print a line of memory information to pout()

getPeakMemoryFromOS()

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.

getMemoryUsageFromOS()

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.

get_memory_usage_from_OS()

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.

gather_memory_from_procs()

void gather_memory_from_procs	(	Real	end_memory,
		Real &	avg_memory,

	)

reduce_print_avg_min_max()

void reduce_print_avg_min_max	(	const char *	s,
		Real	value
	)

reduce_avg_min_max()

		Real &	avg,
		Real &	min,
		Real &	max
	)

reduce_avg_min_max_loc()

int reduce_avg_min_max_loc	(	Real	value,
		Real &	avg,
		Real &	min,
		Real &	max,
		int &	minloc,
		int &	maxloc
	)
