Integration Services :: Execute Stored Procedures In Parallel And Dynamically?

I have a stored procedure. It can be executed like this

exec test @p = 1;
exec test @p = 2
exec test @p = n;
n can be hundred.

I want the sp being executed in parallel, not sequence. It means the 3 examples above can be run at the same time.
If I know the number in advance, say 3, I can create 3 different Execution SQL Tasks. They can be run in parallel.

However, the n is not static. It is coming from a table. 

How can I execute Stored Procedures in PARALLEL and DYNAMICALLY ?

I think about using script task. In the script, I get the value of n, and the list of p, from the table, then running a loop with. In the loop, I create a threat and in the threat, I execute the sp like : exec test @p = p. So the exec test may be run parallel. But I am not sure if it works.
