ttime3

C synopsis

#include <net.h>
double ttime ();

Fortran synopsis

double precision FTTIME()

Overview

The ttime() function enables a program running on any LAM node to read the current value of the system timer in a portable fashion. This is useful for measuring execution times of program sections. ttime() returns the timer value in seconds as a double precision floating point number.

Examples

#include <stdio.h>
#include <net.h>
double	time, start, end;
start = ttime();
my_sub();
end = ttime();
time = end - start;
printf("my_sub took: %f seconds to execute\n", time);
