[Beowulf] New tools from FB and Uber

[Lachlan Musicman]

I always find it weird when companies I don't like release new toolsets
that make me begrudgingly think that they are not evil to the core.

FB has open sourced some interestimg kernel tools, including 'cgroups2' and
btfrs (!! Wasn't that already floss?)

https://code.fb.com/open-source/linux/

Uber has released a new player in cluster workload management, Peleton

https://eng.uber.com/peloton/

Enjoy your morning reading!

I vaguely remember hearing about Btrfs from someone at Oracle, it seems the main developer has moved around a bit since!

Yeah Chris Mason (and another) left Oracle for Fusion-IO in 2012 and
then shifted from there to Facebook in late 2013. Jens Axboe (the
kernel block layer maintainer) also moved from Fusio-IO to Facebook
shortly after (early 2014).

FB run btrfs on a bunch of their infrastructure which helped them find
problems at scale (from memory, I don't track it any more).

All the best,
Chris

Btrfs has been around for a while, and has even been in the Linux
kernel for a while.

I'm guessing that Facebook has had their own development branch which
they are now making public as that link differs from the development
branch that is shown on the kernel Btrfs page:

https://btrfs.wiki.kernel.org/index.php/Btrfs_source_repositories

Currently I believe only OpenSUSE ships it in a supported form, Red
Hat announced they are removing support and it won't be in future
releases.

It's been supported on Oracle Linux for a long time(since 6.3 I think)
