#include <net.h> double ttime ();
FORTRAN SYNOPSIS
double precision FTTIME()DESCRIPTION
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.EXAMPLE
-
#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);
BUGS
The resolution of the measurements is bound by that of the underlying system timer used.Contenus ©2006-2024 Benjamin Poulain
