@StephanEwen from the discussion of FLINK-3163 I also had the idea of
`taskmanager.compute.fraction` where the number of slots would be a multiple of
the number of cores / vcores. Since Flink processes these as opaque strings the
only purpose is to help organize [config
page](https://ci.apache.org/projects/flink/flink-docs-master/setup/config.html).
I have found YARN-5764, MESOS-5342, and MESOS-314 discussing NUMA support
for containers but all are works in progress. I see that Docker supports
`--cpuset-cpus` and `--cpuset-mems` in [docker
run](https://docs.docker.com/engine/reference/run/) and in [docker
compose](https://docs.docker.com/compose/compose-file) config version 2 (using
`cpuset`). It's not clear how to dynamically bind Flink to numa nodes without
scripting Flink's docker commands.
