09:00 Introduction & goals of the day - Ian Bird (CERN)
Introduction & goals of the day
- Ian Bird (CERN)
09:00 - 09:30
Focus on how to work towards a model for computing for the HL-LHC era. What are the areas where we need to invest R&D, how do we being to understand the likely costs?
09:30 Summary of top concerns of the experiments - Ian Bird (CERN) Daniele Bonacorsi (University of Bologna) Eric Christian Lancon (CEA/IRFU,Centre d'etude de Saclay Gif-sur-Yvette (FR)) Stefan Roiser (CERN) Predrag Buncic (CERN) Andrej Filipcic (Jozef Stefan Institute (SI))

11:00 Infrastructure models - Simone Campana (CERN)
Infrastructure models
- Simone Campana (CERN)
11:00 - 12:30
<ul> <li>How to reduce the overall cost of the infrastructure, e.g. by: <ul> <li>Reducing the amount of scattered storage <li>How to procure and incorporate large scale compute resources at scale <li>What is the networking model - OPN–style private? <li>The use of other resources: HPC, volunteer, etc. What is the model for distributed sites (Tier 2)? </ul> <li>The idea of setting up an early prototype of a data/cloud infrastructure to test ideas (a la “Zephyr” proposal) - suggestion already supported by several Tier 1s <li>What about specialist sites/resources (HPC, GPU etc) for specific workflows <li>Security considerations, especially access control and how that affects performance and cost </ul>

12:30 - 14:00
14:00 Experiment workflows & data management tools and infrastructure - Daniele Bonacorsi (University of Bologna)
Experiment workflows & data management tools and infrastructure
- Daniele Bonacorsi (University of Bologna)
14:00 - 15:00
<ul> <li>Can we think about common toolsets for all experiments, given 10 years until HL-LHC? <li>Input on data management convergence from previous day <li>What is realistic in terms of common infrastructure and services in order to achieve commonality? <li>More commonality is an expectation of funding agencies. <li>Political limitations? e.g. specific project funding? <li>Many sites (esp Tier 1s) have to support other sciences on the same infrastructure </ul>
15:00 Technology Evolution - Bernd Panzer-Steindel (CERN)
Technology Evolution
- Bernd Panzer-Steindel (CERN)
15:00 - 16:00
<ul><li>Should we set up a technology tracking activity (as Bernd has been doing), but perhaps now realised together with the concurrency forum and the tech lab activity – to provide a real testing and benchmarking environment (openlab here too). <li>Could be a distributed collaborative effort - in common with HSF/concurrency forum </ul>

16:30 Undesrtanding and modelling of the distributed infrastructure & computing models - Markus Schulz (CERN)
Undesrtanding and modelling of the distributed infrastructure & computing models
- Markus Schulz (CERN)
16:30 - 17:30
<ul> <li>How well do we understand our current workflows, their behaviour and resource needs? <ul> <li>with respect to storage, remote access, networks, CPU, memory <li>How well do we understand the behaviour of our current infrastructure? <li>What can we do to improve this understanding in an experiment independent way? <li>how independent can this be? </ul> <li>What has been done already in experiments? <li>What would be desirable? Ability to model ideas of infrastructure to understand performance, costs, etc. <li>What is potentially common across experiments? What is specific? <li><b>Can we derive a cost model for the infrastructure to explain the full costs of computing and the relative costs of each component?</b> </ul>

09:00 Software topics - Benedikt Hegner (CERN)
Software topics
- Benedikt Hegner (CERN)
09:00 - 10:00
<ul> <li>What is actually useful to do in common? <li>Tools or support for common automated and intelligent build/test/validation services? <li>More ? Common libraries etc? Role of HSF <li>What is usefully shareable? <li>Detailed software performance analysis and tools for analysis <li>All this should be in the context of the HSF. Some activities towards common (lower-level) build tools was started already. Organise a dedicated HSF workshop on this?- <li>Do experiments actually want to commit to the HSF for common software interests? <li>Given today's (and expected evolution of) processor and machine architecture, is today's data architecture (i.e. ROOT) appropriate - do we need to re-think completely? </ul>
