From d923fb784f4f429c066ceb807c669a4308c1d9b4 Mon Sep 17 00:00:00 2001 From: Jeroen Bakker Date: Fri, 17 Apr 2020 10:00:54 +0200 Subject: Task: Separate Finalize into Reduce And Free In preparation of TBB we need to split the finalize function into reduce and free. Reduce is used to combine results and free for freeing any allocated memory. The reduce function is called to join user data chunk into another, to reduce the result to the original userdata_chunk memory. These functions should have no side effects so that they can be run on any thread. The free functions should free data created during execution (TaskParallelRangeFunc).
