Here is an example of how to implement the right degree of parallelism in C# using the Task Parallel Library (TPL): Define the task: Start by defining the task that needs to be executed in parallel. void Main() { List<int> numbers = Enumerable.Range(1, 100).ToList(); Divide the task: Divide the task into smaller, independent subtasks that can be executed simultaneously. int chunkSize = numbers.Count / 4; // 4 subtasks Create tasks: Create a task for each subtask using the Task class. var tasks = new List<Task>(); for (int i = 0; i < 4; i++) { int start = i * chunkSize; int end = (i + 1) * chunkSize - 1; tasks.Add(Task.Run(() => ProcessNumbers(numbers, start, end))); } Wait for tasks to complete: Wait for all tasks to complete using the Task.WaitAll method. Task.WaitAll(tasks.ToArray()); } ...
