Subject: [pve-devel] [PATCH-SERIES proxmox-{resource-scheduling, perl-rs}] fix scoring issue with overcommitted node
Date: Tue, 21 Mar 2023 13:33:41 +0100	[thread overview]
Message-ID: <20230321123345.128141-1-f.ebner@proxmox.com> (raw)

The current algorithm is blind in cases where the static node stats
are the same and there is (at least) one node that is overcommitted
when compared to the others.

The problem is that using the linear average produces the same values
for the alternatives (except for the overcommitted node). Fix it by
using a nonlinear average.

The patch proxmox-perl-rs 2/2 requires a build-dependency bump for
proxmox-resource-scheduling.
