It was emphasised that the concerns of all member of the group
should be aired and used to guide the group's activities.

Agreed that the group's activity is open - any interested parties can
sign up and attend our meetings.

There is a mailing list we can re-use for this group. ACTION Graeme
and Wesley to try to re-enable this.

Should have systems designed to cope with pile up up to 200. Noted
that ATLAS and CMS cannot be triggerless (too high a material cost).

Still hard to see how we bring our software into shape for really
exploiting parallelism. 25% Moore's Law increases probably not
enough.

For contacting groups outside the experiments we can use the
Concurrency Forum and HEP S/W.

Talks this year can report on progress that the experiments have made
- thus expect more concrete results. Focus is on runs 3 and 4, however
relevant information from run 2 upgrades can be illustrative. We need
to make sure that we have sufficient resources for the TDAQ and
computing upgrades - don't underestimate the costs and diffculties.

Workshop last year was very useful. General consensus that first week
of September would be a good time for mini-workshops (too many
constraints in subsequent weeks). These should be topical and can
cover each area of interest independently (although trigger and
offline S&C issues are quite close; noted that generally online
resources are now used more flexibly). Speakers for the meeting should
help guide inputs. Discussions within communities should be prompted
by PG members.

Speaker selection: Last year, generally, people did not volunteer - so
David and Wesley both spoke. There is room for up to 4 talks and we
can pick advocates to really push on key points. PG Chairs can speak
for the group, but this is not necessary. We should decide on speakers
and topics early to help with mini-workshop preparations. ACTION for
ALL - Suggestions and nominations here are already very welcome!

Useful reference materials should be added. ACTION on ALL - please
send relevant links to Graeme and Wesley. (In particular LHCb TDRs are
available.)
 
For 'white papers' the twiki should suffice for people to submit
ideas.

Next meeting will be in ~2 weeks to discuss progress and continue
preparations.
