merge All tests fine, haven't checked memory use yet though. @boudoul, there will be some memory improvement in the next release in case you want to try HGCal relvals again. |
Reduce HGC rechit memory footprint
@mark-grimes if you've got a script, config, and file I can use to make a realistic test please send by email and I'll check the memory usage. |
Remove a merging module that is un-necessary, should reduce HGC rechit memory footprint by 2x.
Trying to get a working rechit creator that can service all three HGC subcomponents at once, removing the need for a merging module. For some reason it will not let any rechits pass. I working on a fix since this is necessary to keep the memory use down once we start collection rechits in the whole detector at once.
This is a decent patch for now since the subcomponents are clustered separately in this version of HGC RECO.
Last commit should help reduce the retained memory by quite a bit.
