Suppose you have the program::
finish for ((i) in 0..N-1)
async doComputation(i);
where N is very large. This will spawn N asyncs. Now you only have P
cores. So you can write this as:
val step = N/P;
finish for ((p) in 0..P-1)
async
for ((i) in step*p..step*(p+1)-1)
doComputation(i);
This will spawn only P asyncs, but all the original work will get done.
This will give you the same result as the first (but better performance)
provided that doComputation(i) does not throw any exceptions.
