Thanks.
Well, U ask me to be more specific.
I'll do that.
I need to write a procedure that checks and prints the prime numbers
between 1 and m.
The procedure gets 2 parameter, m- the numbers to check 1..m and n - the
number of tasks to perform it.
each tak will check if a number is a prime number, and will update an array
of booleans (size 1..m).
At the end of all tasks the procedure prints the prime numbers.
A managment task should manage all the tasks allocations ...
Regards,
Janiv Ratson.
