Proposed Changes
When accessing the adjoints, bounds checking acquires an internal lock in CoDiPack. This turned out to be a bottleneck in
InitializeAdjointandIterateDiscreteAdjoint. Therefore, we ensure sufficient size up front and skip the bounds checking.Related Work
Previous work on hybrid parallel AD, like #1214, #1284, #1294.
