time

[zhly0]

@luoyetx thanks for your nice work!the code is really simplified for caffe inference.
and there is a question:
when I use the time count:
clock_t start = clock();
clock_t end = clock();
float time = (float)(end - start) / CLOCKS_PER_SEC;
the time I get is about 1000ms,but when I use profiler in the mini-caffe,the time I get is about 250ms,I know the clock() is not so accurate,and the time it get is about twice of profile,but why I get four times?

@zhly0 consider to use profiler, see this doc

clock() will sum the time of all threads.

use
#include <omp.h>
double t1 = omp_get_wtime();
...
double t2 = omp_get_wtime();
printf("time = %.3f seconds\n",t2-t1);
