AIDAinnova Notes

Present: Graeme, Frank, Thomas, Anatolii, Anna, Hadrien, Juan, Peter, Piyush, André, Swathi

Apologies: John

Introduction

Anna - it should be ok to have the deliverable ready for 9 December

Key4hep

Deliverable template link is in the introduction. Deadline for the draft would be 20 January.

Julia link issue is really about PODIO, not EDM4hep.

Having EDM4hep 1.0 would be a great achievement for Key4hep (and thus AIDAinnova).

Simulation

L2LFlows inference time is independent of enegy.
The other methods are linear with energy, but not with a zero intercept!

Great to have these comparisons, they will be in the final report.

Tracking

Traccc data structure changes motivated by differences in compilers for GPU and CPU. GPU compilers like to have many more variables in registers as fetching from memory is very expensive on the GPU. However, many registers used per thread can throttle the number of active threads in a warp.

PFA

See John's slides.

AOB
