Dr Alexei Klimentov (Brookhaven National Lab), Shawn McKee (University of Michigan)

6/9/26, 9:00 AM

Welcome and quick preview of the next 2 days.

69. ADC Priorities During LS3 and Site Procurement implications

Ivan Glushkov (BNL)

6/9/26, 9:05 AM

What should be we planning on doing for infrastructure updates?
- ARM compute servers?
- GPU servers?
- Storage servers, specifically what are the needed charactistics?
- Netwoking: how do we get to 400 Gpbs links by HL-LHC startup?
- Infrastructure: power, management, resiliency, capacity; what do we need?
- Services: what middleware and are changes needed in services we deploy?
...

68. T1/T2 Priorities and Hardware Cost Mitigations

Frederick Luehring (Indiana University), Kaushik De (University of Texas at Arlington)

6/9/26, 9:30 AM

We need to discuss facility priorities during the upcoming LS3.

• US ATLAS pledge resources
• More important: infrastructure upgrades
• Common tools for US sites (perhaps new AI tools)

We also need to explore our current cost environment and its implications for our facilities. With no additional "bump" of funding foreseen before HL-LHC, how can we optimize our resource...

Are there technologies or services our sites should deploy broadly?
What are the available storage components for USATLAS, both in-use and available? Pros/Cons?

74. Storage Policies for USATLAS Users

Ofer Rind (BNL)

6/9/26, 3:30 PM

We need to discuss our plans for storage supporting the needs of our USATLAS users.

Open discussion on session items.

Need to gather scrubbing related items by WBS area.

How will we operate during LS3?
How will we meet ATLAS needs for HL-LHC, given our funding and cost environment?

84. RP1 Core, Open Data Facility and Implications for AFs in the HL-LHC era

Aidan Rosberg (Indiana University)

6/10/26, 9:45 AM

Aidan will present on RP1 and Open Data. We can use this as a springboard to discuss needs for AFs during HL-LHC.

85. Discussion, Wrap-up including USATLAS Topics for WLCG-HSF November Meeting

6/10/26, 10:05 AM

We need to discuss what items we want to cover during the WLCG-HSF meeting in November. What are the important (to USTATLAS) topics and what our our goals for the meeting?
