Release Notes

flux-core version 0.51.0 - 2023-06-09

This release adds the flux-batch(1) and flux-alloc(1) --conf option, which makes subinstance configuration significantly easier. Sys admins may note that named configurations can be added to /etc/xdg/flux/config for configurations that are anticipated to be commonly needed such as node-exclusive scheduling.

For example, /etc/xdg/flux/config/node-exclusive.toml could contain:

[sched-fluxion-resource]
match-policy = "lonodex"

And then users could request this in a batch subinstance with:

flux batch --conf=node-exclusive ...
