affinity_partitioner¶
[algorithms.affinity_partitioner]
Hints that loop iterations should be assigned to threads in a way that optimizes for cache affinity.
An affinity_partitioner hints that execution of a loop template should use the same task affinity pattern
for splitting the work as used by previous execution of the loop (or another loop) with the same affinity_partitioner object.
affinity_partitioner uses proportional splitting when it is enabled for a Range type.
Unlike the other partitioners, it is important that the same affinity_partitioner object
be passed to the loop templates to be optimized for affinity.
The affinity_partitioner class satisfies the CopyConstructibe requirement from the ISO C++ [utility.arg.requirements] section.
