Dear all,
as some of you might have already noticed the F@H jobs are draining. I
stopped submitting them because
the number of WUs (Work Units or payloads) being served to CPUs is quite
low.
Also there are some mammoth resources being enabled else where in the
WLCG experiments. For example
ATLAS just created a dedicated workflow that can be submitted to all
ATLAS sites at no notice and will be
monitored, tracked and accounted by ATLAS as a one of the analysis
activities.
So I recommend to increase the biomed priority too to avoid duplicating
similar efforts on the same resources.
If we want this to be restricted to COVID only, we need to tell biomed
and they'll set the appropriate tags for
UK sites as per email below.
cheers
