Function Documentation

RunAsync()

void Gorgon::Threading::RunAsync

(

std::function< void()>

fn

)

Executes a function asynchronously.

This function starts the thread immediately. There is no way to wait for the thread, stop or query its execution.

Parameters

fn	the function to be executed.

RunInParallel()

void Gorgon::Threading::RunInParallel	(	std::function< void(int, int)>	fn,
		unsigned	threads = 0
	)

Runs a function specified amount of times in parallel.

threads parameter controls the amount of parallel executions. This function will return when all threads it controls finishes. The following example performs an operation over the data vector using 4 threads. If the threads parameter is omitted, the number of threads supported by hardware is used.

std::vector<int> data(1000);
RunInParallel([&data](int threadid, int threads) {
   for(int i=threadid;i<data.size();i+=threads) {
       //... do something with data[i]
   }
}, 4);

Parameters

fn	is the function to be executed. First parameter of the function should be thread id, second is the number of threads. See the example.
threads	the number of threads to be executed.
