Danilo Piparo (CERN)

Minutes: Xavi, Massimo, Enrico, Enric, Stefan, Javi, Pere, Lorenzo, Philippe, Guilherme, Danilo

ACTIONS

Xavi: clarify the interplay of arenas and number of workers used.

Massimo:

Constructive comments given, see you at the SFT meeting.

Xavi:

- There is a positive feeling about the change proposed. The only thing we need to take care of is the work stealing within ROOT itself and between ROOT and other libraries potentially using the same pool.

- We need to be clear about how the threads are managed by the arenas.
