> An interesting anecdote from this month's Linux Plumbers Conference in Tokyo is that Meta (Facebook) is [1]using the Linux scheduler originally designed for the needs of Valve's Steam Deck... On Meta Servers . Meta has found that the scheduler can actually adapt and work very well on the hyperscaler's large servers. [...]

> The presentation at LPC 2025 by Meta engineers was in fact titled "How do we make a Steam Deck scheduler work on large servers." At Meta they have explored SCX_LAVD as a "default" fleet scheduler for their servers that works for a range of hardware and use-cases for where they don't need any specialized scheduler. They call this scheduler built atop sched_ext as "Meta's New Default Scheduler."

> LAVD they found to work well across the growing CPU and memory configurations of their servers, nice load balancing between CCX/LLC boundaries, and more. Those wishing to learn more about Meta's use and research into SCX-LAVD can find the Linux Plumbers Conference presentation embedded below along with the [2]slide deck (PDF).

Now we know what these many GPUs are for (Score:2)
Clever of those Meta engineers to convince the C-level to buy all those expensive GPUs "for AI"... while they are having the biggest LAN-party of all times in the now well-equipped data center ;-)

If someone is commissioning a billion dollar GPU scale-up and not asking "Can this thing play Crysis" , then one is GPUing wrong.

Wait. Meta is Facebook??
That's insightful, right there, I don't care who the mods are.

he kickstarted a revolution in linux scheduling. hard to believe it's been nearly 20 years since

Probably living like a king from mining crypto in the early 2010's. Hopefully he is still contributing to the Multiple Queue Skiplist Scheduler, aka Brain Fuck Scheduler.
Varying schedulers common on Android (Score:2)
One of the interesting things about the Android Linux scene is that it's common for distributions to have various user-selectable schedulers. This seems kind of unusual on desktop Linux.
