C++ (Cpp) time_func Examples

Example #1

File: overhead_cmpxchg.c Project: Caleb-Wolfe/network-testing

int main()
{
	printf("Measuring unlocked cmpxchg:\n");
	time_func(LOOPS, loop_cmpxchg);

	printf("Measuring locked cmpxchg:\n");
	time_func(LOOPS, loop_cmpxchg_locked);

	printf("Measuring implicit locked xchg:\n");
	time_func(LOOPS, loop_xchg);

	return 0;
}

Example #2

File: list_tests.c Project: sproates/ocarina

void list_tests(void) {
  unsigned int millis;

  printf("Running list performance tests.\n");

  printf("Running list_append() tests.\n");
  millis = time_func(_test_append);
  printf("Test took %d sec %d millis CPU time\n", (int)(millis / 1000), (int)(millis % 1000));

  printf("Running list_remove() tests.\n");
  millis = time_func(_test_remove);
  printf("Test took %d sec %d millis CPU time\n", (int)(millis / 1000), (int)(millis % 1000));

  printf("Completed list tests.\n");
}

Example #3

File: syscall_overhead.c Project: Caleb-Wolfe/network-testing

int main()
{
	printf("Measuring syscall getuid:\n");
	time_func(LOOPS, loop_syscall_getuid);

	return 0;
}

Example #4

File: microbench.c Project: DiamondLovesYou/jemalloc

void
compare_funcs(uint64_t nwarmup, uint64_t niter, const char *name_a,
    void (*func_a), const char *name_b, void (*func_b))
{
	timedelta_t timer_a, timer_b;
	char ratio_buf[6];

	time_func(&timer_a, nwarmup, niter, func_a);
	time_func(&timer_b, nwarmup, niter, func_b);

	timer_ratio(&timer_a, &timer_b, ratio_buf, sizeof(ratio_buf));
	malloc_printf("%"PRIu64" iterations, %s=%"PRIu64"us, "
	    "%s=%"PRIu64"us, ratio=1:%s\n",
	    niter, name_a, timer_usec(&timer_a), name_b, timer_usec(&timer_b),
	    ratio_buf);
}

Example #5

File: main.cpp Project: 1nate146/csc-212-s16-code-examples

int main(int argc, char **argv) {
//  DynArray array_1(??);

    // get argument from command line (how many consecutive appends?)
    ul_int n = atoi(argv[1]);

    // measure time for each call
    time_func(&array_1, n);

    return 0;
