8. Introduction

Graeme A Stewart (CERN)

5/11/20, 4:00 PM

1. Code Portability

Dr Charles Leggett (Lawrence Berkeley National Lab (US))

5/11/20, 4:06 PM

• Different hardware available and foreseen
• Features of main APIs for heterogeneous projects.
• Projects that are looking at this topic and plans
• Experiences so far

2. Heterogeneous Architectures and Detector Simulation

Dr Guilherme Amadio (CERN)

5/11/20, 4:44 PM

We discuss attempts to develop libraries for adapting detector simulation (mainly) to new architectures, giving an overview of these codes, prospects for porting to other architectures and what has been learned in the process.

• HEP specific libraries: VecCore, VecGeom, VecMath
• Specific hardware features and their likely impact on HEP codes

3. TensorFlow as a Compute Engine

5/11/20, 5:22 PM

The use of Google TensorFlow as a general purpose parallel computing engine, using TensorFlowAnalysis as an example

4. Application Frameworks

Attila Krasznahorkay (CERN), Christopher Jones (Fermi National Accelerator Lab. (US)), Dr Kyle Knoepfel (Fermi National Accelerator Laboratory)

5/12/20, 4:00 PM

How experiment frameworks are adapting to heterogeneous landscapes

5. Workload Management

Antonio Perez-Calero Yzquierdo (Centro de Investigaciones Energéti cas Medioambientales y Tecno), Doug Benjamin (Argonne National Laboratory (US)), Ricardo Brito Da Rocha (CERN)

5/12/20, 5:00 PM

Scheduling for heterogeneous resources; multi-node slots (HPCs)

7. Benchmarking and Accounting Metrics

Domenico Giordano (CERN), Markus Schulz (CERN), Michele Michelotto (Università e INFN, Padova (IT))

5/13/20, 4:00 PM

• How do we value heterogeneous resouces?
• What jobs would be used ?
• Can their efficiencies be considered the same?

6. Validation

Adriano Di Florio (Universita e INFN, Bari (IT)), Ines Ochoa (Columbia University (US))

5/13/20, 5:00 PM

• How to validate on multiple architectures?
• What's 'the same physics'?
• How to do this practically, testing each architecture and automating

9. Closing Remarks
