Analysis Ecosystems II Workshop Report

This is now ready in its beautiful LaTeX version and ready to be uploaded to arXiv with the full list of authors.


Our colleagues in the ESCAPE project invited Graeme to give a talk about aligned HSF activities at their workshop last week. The presentation focused on:

ESCAPE is in the process of transitioning from a project to a consortium and we do foresee future cooperation with our colleagues there.

Pre-CHEP Workshop

Discussing with WLCG colleagues and LHC computing coordinators we have identified topics for a pre-CHEP workshop on 6-7 May 2023 in Norfolk, VA. Two areas where software and facilities are close are:

Will communicate this back to local organizers. We don’t know how much remote participation will be supported (the CHEP venue contract was signed pre-COVID).

Scientific organising committee needs to be setup soon.

Letter of Cooperation Request

We have been approached by Mike Sokoloff to provide a letter of cooperation for an NSF proposal to develop massively parallel and high-dimensional fitters.

Unfortunately no public text has been made available.

We are minded to support this, but from the HSF Coordination Group instead of the whole HSF? (The coordination group has seen a draft, which we can share on request.) Generally we discourage this, however. A community organisation like the HSF is not well suited to providing support to private proposals.

Liz - if this was a request that can be delivered by the Coordination Group, e.g., a workshop, it might be possible to give limited support. But for the whole of the HSF it’s difficult if there is no public document.

Benedikt - coordination team are volunteers, not an executive, not really empowered to take unilateral decisions. Could he make something public just a few days before the deadline.

Outcome: we ask Mike to either prepare a public summary or to agree to upload a few days before the submission deadline the proposal. Graeme will communicate this decision back to Mike.

Working Group Updates


We have concluded on the first round of invitations to new WG conveners. Many people have accepted already and we have quite a few pending responses. Overall we are making good progress and hope to have most of the WGs settled before the break.

We are short of candidates in Tools and Packaging, so if you have names please let us know.

Reminder: In January we will have a review of the year gone, as well as looking forward to 2023 - so please think about it.


Reminder: Please try and book meetings in Indico at least 2 weeks in advance!

That way they go into the calendar early and they will be included in the weekly email announcement that goes to HSF Forum.

Data Analysis

Detector Simulation

Reconstruction and Software Trigger


Software Training

C++ Course and Hands-on Training

Two new courses planned:

Other Interest and Activity Areas

Compute Accelerator Forum

Software and Computing Roundtable


January visit to India from key people is going ahead, to gather support for the project. Proper kick off meeting to follow in the Spring. There will also be a talk at the ASGC meeting next year.


Linux Future

News hot off the press is that CERN will be recommending and supporting AlmaLinux 8/9 and Red Hat Enterprise Linux 8/9 (moving away from CentOS Stream).

HSF Calendar

This should be complete - LHCC weeks for 2023 are now added.

Next Meeting

The first meeting next year is January 19, where we will start by reviewing 2022 and planning for 2023. It would be great to identify a highlight point from each WG, which can be used as a way to communicate the role and effectiveness of the HSF.
