TICLGeom: do not schedule the @alpaka geometry ES producers in FastSim by felicepantaleo · Pull Request #51657 · cms-sw/cmssw

felicepantaleo · 2026-08-09T09:33:08Z

Phase2 FastSim is a phase2_hgcal process that loads no Alpaka backend and runs no HGCal reco, so scheduling the @alpaka TICLGeom EventSetup producers made the EventProcessor fail to find the plugin at construction.

Comparison Summary

There are some workflows for which there are errors in the baseline:
36434.0 step 2
The results for the comparisons for these workflows could be incomplete
This means most likely that the IB is having errors in the relvals.The error does NOT come from this pull request

@alpaka

Add the @alpaka TICLGeom EventSetup producers to hgcalLocalRecoTask instead of attaching them to every phase2_hgcal process. Their EventSetup modules are then instantiated only when the reco task is scheduled, which is where the Alpaka accelerator is present, so a process that only loads the reconstruction sequence without scheduling it (FastSim, the tracker geometry dump tests) no longer fails to find TICLGeomESProducer@alpaka at EventProcessor construction.
