'Number_Of_CPUs' tasks creation, with discriminants, running simultaneously.

[Olivier Henley <olivier.henley@gmail.com>]

Hi everyone,

My goal is to distribute similar work across multiple tasks. Incidentally, I want those tasks to start simultaneously, each task having some 'indexed' work (discriminants), and ideally block from main until they are done with their workload.

I got this working by declaring the tasks individually. What I would like to achieve is to leverage 'System.Multiprocessors.Number_Of_CPUs' for the number of tasks created. What is the idiomatic way of achieving what I want?

I tried with an array of tasks, but the problem becomes I do not know either how to start them simultaneously with parametrization or coordinate their exit point with main.  

I am lurking for the most 'clean/simple' solution possible.  

You can see the actual working code fixed at 8 tasks here:
