LocalTaskQueue (SystemDS 2.2.1 API)

```
public class LocalTaskQueue<T>
extends Object
```
This class provides a way of dynamic task distribution to multiple workers in local multi-threaded environments. Its main purpose is inter-thread communication for achieving dynamic load balancing. A good load balance between parallel workers is crucial with regard to the overall speedup of parallelization (see Amdahl's law). From a technical perspective, a thread monitor concept is used for blocking of waiting writers and readers. Synchronized writes and reads ensure that each task is only read by exactly one reader. Furthermore, the queue is implemented as a simple FIFO.
