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 
)

verison that does not convert things to floating-point values
