CHIPP computing steering group:

the group has been re-organized leading from one member/insitute to one member/experiment (mirroring the technical group).

The members are:

- ATLAS: Steven Schramm (UniGe)

- CMS: Clemens Lange (PSI)

- LHCb: Lesya Shchutska (EPFL)

ATLAS report:

There seems to be an inconsistency in the disk size reported in the table and the one in CRIC 1904TB ?

DPM migration, situation clarified:

we can move to the new storage hw (noew received - see Nick slides) and then decommision the old DPM "test-hw" and keep the federation

At the moment the ATLAS Tier-2 report correclty contains the officlal tables. In this way on the other hand we miss the usual sanity check between "Nick's numbers" and "Gianfranco's numbers". It would be useful to also report the ATLAS numbers refering to the pledges asked at CSCS.

CSCS report:

Pablo: it would be useful to also past the plot with the number of pending jobs to simplify the understand of the "Running cores" plot

New plot showing directly HS06 simplifies the comparison with pledges

WLCG final pledges for 2022 to be frozen in CRIC by Sept 30.
