2017-12-20Prevent false sharing in lightbaker RNG stateHein-Pieter van Braam
The previous commit corrected the RNG behavior for the lightbaker but also made it significantly slower on high core count systems. Due to the vector of states being physically close together in RAM we force a cache synchronization across all cores whenever we call for the next random number to be generated. This will create a temporary local copy of the RNG state before entering the loop and then saving it back to the global state when done. This will preserve the per-thread RNG state (and random number quality) while significantly improving performance. On my 16 thread box it saves 3 minutes baking the Sponza scene, bringing performance back in line to before the various RNG fixes were introduced, being slightly faster than the first implementation.
2017-12-20Fix lightmapper rngHein-Pieter van Braam
In our previous attempts to fix the lightmapper we may have inadvertently introduced the same issue we were trying to fix. It appears that rand() will on some platforms introduce a mutex making it slower and on others may have a per-thread state that would need to be initialized with srand() on each thread. This slows down the lightbaking further. This sets up a separate rng state for each OpenMP thread by calling rand() only in the single-threaded part of the code. We then keep a vector of states. I believe this solves our problems.

Use a more naive RNG for the lightmapper
2017-12-17Add several unlikely() macrosHein-Pieter van Braam
Based off of perf-based prediction misses these seem to be the lowest-hanging fruit for quick (albeit small) improvements. These are based on: * baking a complex lightmap * running platformer 3d * running goltorus
2017-12-17Tweak OpenMP parameters for lightbakerHein-Pieter van Braam
On higher threadcount systems this allows for better utilization. On my 16 thread box CPU use goes from 10 - 11 threads to a steady 15 threads on the Sponza scene. Baking time goes from ~10:00 to ~07:30 for me. On lower threadcount systems I expect some improvement also but likely a little less.

This speeds up the lightmapper by about 10% with no visible impact.
