Detailed Description

Timer and resource monitor.

Examples

hpFEM2d.cc, and hpFEM3d-EV.cc.

Constructor & Destructor Documentation

ResourceMonitor()

concepts::ResourceMonitor::ResourceMonitor ( )

inline

Default constructor.

Initializes the timer and resource monitor, ie. fills ru_.

Definition at line 41 of file resourceMonitor.hh.

Member Function Documentation

sample()

std::ostream& concepts::ResourceMonitor::sample

(

std::ostream &

os

)

Returns an output stream with resource information.

There are timing information since construction or last output and memory usage information of the process.

Example:

3.21s [utime = 6.36s, stime = 3.09s, minflt = 0, majflt = 0, maxrss = 0.00KB]

the numbers before the [] gives the user and system time since the last output. The time values in the [] are the cumulated user and system time since the process started.
minflt gives the number of page faults not requiring physical I/O
maxflt gives the number of page faults requiring physical I/O
maxrss gives the memory needed by the process

utime()

float concepts::ResourceMonitor::utime

(

)

Returns the user time since the last call of ResourceMonitor using getrusage.

This is not very precise (1/100 sec).

Examples

hpFEM2d.cc, and hpFEM3d-EV.cc.
