Possible performance bug in ray_ground_classifier
Description
I think something is wrong with our use of OpenMP.
To reproduce
set(use_OMP FALSE)
in ray_ground_classifier
and ray_ground_classifier_nodes
.
Expected
The CPU load of the ray_ground_classifier is about the same when using OpenMP or not, because it's the same work, just spread out over more cores.
Observed
The CPU load when using OpenMP (the default) is 450%, and 3% without.
