Parallel Programming in C# : Patterns

	// Problem:
	// We have lots of data that we want to process that can be easily parallelised
	// We want to process all our data and combine the results
	// "Map is an idiom in parallel computing where a simple operation is applied to all elements of a
	// sequence, potentially in parallel.[1] It is used to solve embarrassingly parallel problems: those
	// problems that can be decomposed into independent subtasks, requiring no
	// communication/synchronization between the subtasks except a join or barrier at the end."
