38th ROOT Parallelism, Performance and Programming Model

Thursday 19 Apr 2018, 16:00 → 17:45 Europe/Zurich

4/S-030 (CERN)

Danilo Piparo (CERN)

Present: Augusto, Guilherme, Enrico, Stefan, Kim, Enric, Danilo, Jim, Philippe

Actions:

Danilo: communicate to Augusto way to change the compilation flags in cling

Augusto: try out pyROOT

Hydra:

- The differences between aclic/g++ and interpreted are understood. It is nice to see aclic and compiled examples having the same timing!

- Hydra works quite well with ROOT: macros were included in Hydra too.

Round Table

PyROOT

- Conversion of contiguous memory to numpy array implemented

- Conversion of datasets into numpy tables

- TDF is exploited and therefor ImplicitMT used during the conversion!

Parallel Writing

- Test fixed

- Remove the merging thread
