Timer

This class is able to measure time (in seconds) elapsed in a particular period. Example:

lua

  timer = torch.Timer() -- the Timer starts to count now
  x = 0
  for i=1,1000000 do
    x = x + math.sin(x)
  end
  print('Time elapsed for 1,000,000 sin: ' .. timer:time().real .. ' seconds')

Timer Class Constructor and Methods

torch.Timer()

Returns a new Timer. The timer starts to count the time now.

[self] reset()

Resets the timer accumulated time to 0. If the timer was running, the timer restarts to count the time now. If the timer was stopped, it stays stopped.

[self] resume()

Resumes a stopped timer. The timer restarts to count the time, and addition the accumulated time with the time already counted before being stopped.

[self] stop()

Stops the timer. The accumulated time counted until now is stored.

[table] time()

Returns a table reporting the accumulated time elapsed until now. Following the UNIX shell time command, there are three fields in the table:

real: the wall-clock elapsed time.
user: the elapsed CPU time. Note that the CPU time of a threaded program sums time spent in all threads.
sys: the time spent in system usage.
