- PROPOSAL: work ongoing, but still mainly on level of proposal and not in the CORSIKA 8 integrated part. Availability of developers currently a bit limited. But hopefully a visible contribution can be made next week.

- Anatoli talks about parallelization, see slides.

Very good and fundamental practical review of the situation.

- Preliminary conclusion:

* we should avoid premature micro-optimization since they tend to be highly architecture dependent and this will change with time!

* Multi-threading is very powerful for air showers.

* GPUs are the potential game-changer. We should try to exploit as far as possible. Even for physics, e.m. cascades may be a target.

* We might need a scheduler to manage parallel tasks.

- Anatoli will prepare a follow-up talk for next week.

- We should focus on these fundamental discussion during next week to get towards first conclusions and more concrete ideas.

 

General:

- CORSIKA 8 focus week starts next week Monday 16:00, then Tue,Wed,Thur: 9am,  Fri ~15:30. There might be additional discussion time slots.
