2 years agoCycles: Improve denoising speed on GPUs with small tile sizes
Lukas Stockner [Fri, 10 Nov 2017 03:34:14 +0000 (04:34 +0100)]
Cycles: Improve denoising speed on GPUs with small tile sizes

Previously, the NLM kernels would be launched once per offset with one thread per pixel.
However, with the smaller tile sizes that are now feasible, there wasn't enough work to fully occupy GPUs which results in a significant slowdown.

Therefore, the kernels are now launched in a single call that handles all offsets at once.
This has two downsides: Memory accesses to accumulating buffers are now atomic, and more importantly, the temporary memory now has to be allocated for every shift at once, increasing the required memory.
On the other hand, of course, the smaller tiles significantly reduce the size of the memory.

The main bottleneck right now is the construction of the transformation - there is nothing to be parallelized there, one thread per pixel is the maximum.
I tried to parallelize the SVD implementation by storing the matrix in shared memory and launching one block per pixel, but that wasn't really going anywhere.

To make the new code somewhat readable, the handling of rectangular regions was cleaned up a bit and commented, it should be easier to understand what's going on now.
Also, some variables have been renamed to make the difference between buffer width and stride more apparent, in addition to some general style cleanup.

Add a new parallel looper for MemPool items to BLI_task.

It merely uses the new thread-safe iterators system of mempool, quite
straight forward.

Note that to avoid possible confusion with two void pointers as
parameters of the callback, a dummy opaque struct pointer is used
instead for the second parameter (pointer generated by iteration over
mempool), callback functions must explicitely convert it to expected
real type.

Also added a basic gtest for this new feature.

3 years agoAdd ability to use more than one mempool iterator simultaneously.

Add ability to use more than one mempool iterator simultaneously.

This will allow threaded tasks to 'consume' all mempool items in
parallel tasks, each one working on a whole chunk at once (to reduce
concurrency managing overhead).

point to right place in code, so should still be OK.

Fix T53145: bevel tool fails when used a second time.

Pixel size was not initial early enough. For first time this was not a problem

This was expected behavior for over-exposured lamps when the mode was originally

real production which will only have green (or rather screen) channel over

Tweaked condition now so we use least bright channel to see if the area has
proper exposure or not.

Seems to work fine in tests, but further tweaks are possible.
