C++ (Cpp) ticks_to_time Examples

Example #1

File: Source.cpp Project: Dzejrou/School-Work

void TestScheduler(const char* msg, const PrimeMap& value, time_sec serialTime)
{
	ticks_t start = now();
	SCHEDULER scheduler(CoreCount);
	std::map<std::size_t, std::size_t> tasks;
	for (std::size_t i = 0; i < Count; i++)
	{
#ifdef VOID_TEST
		tasks[i] = scheduler.add_task([i]() -> void {Test(i); });
		tasks[MaxNum - i] = scheduler.add_task([i]() -> void {Test(MaxNum - i); });

	{
#ifdef VOID_TEST

#else

#endif
	}
	time_sec parallelTime = ticks_to_time(now() - start);
	std::cout << msg << " time = " << parallelTime << " [s]  -  Serial time portion = " << parallelTime / (serialTime / 100.0) << " [%]" << std::endl;
	std::cout << msg << " calculation correct" << std::endl;
