> Libplacebo and the recent FFmpeg Vulkan work were both led by Niklas Haas.

The FFmpeg changes were actually done by long-time FFmpeg...

The slides don't mention it, but VLC 4 also adds Vulkan support

Just chipping in to point out that the 1950X temperatures are fine if properly cooled. I idle at 30-40°C with the fans at ~500 rpm, and max out at 60-70°...

Re: THP and general performance on a NUMA system, I'd like to point out that openSuSE Tumbleweed defaults transparent hugepages to "always"...

That is a very helpful suggestion. Echoing 0 makes the latency spikes less frequent and shorter in duration on average. I can still see some spikes in...

It might be worth pointing out that openSuSE Tumbleweed still uses the (older) SLAB memory allocator, while most other distros stick with the linux default...

Worse than other NUMA systems, by several orders of magnitude. I tested several dual xeon systems, and the results are comparable to the single CPU intel...

It would be interesting to see if they still haven't fixed the memory latency spikes when the machine is under VM pressure. (Orders of magnitude worse...

It would be cool to know if the new threadrippers still suffer from the memory latency issues of the current ones. The tl;dr is that under heavy memory...
