what does this forkjoinreuse and forkjoindeeprecursive mean?

Question

I have been trying to understand this micro-benchmark.

In the source there are four types of ForkJoin: ForkJoinreuse and ForkJoinrecursivedeep. I don't understand in which way they are different from ForkJoin and ForkJoinrecursive, even when I have read the sources.

Answer 1

For these two classes it looks as if there is a precision difference:

ForkJoinRecursive.java versus ForkJoinRecursiveDeep
       'if (slices < 10000)' versus 'if (slices <= 1)'

Overall it appears that the code is trying to use concurrency, i.e. implement multiple threads. Check out the links below for more information.
