Hi again,

so with a fresh update I also now see the recon being x3 slower than this morning. My full recon job takes 140ms/event instead of 50ms/event.

Can people who have committed code today take a look at this and maybe revert to find the source and if itís needed?

Maybe first verify that itís slow.

Iím not sure if I think it runs so much slower. Itís using 100% of one of my cores for sure. Perhaps you can try at a slac node and see if it behaves the same or locally if you are running on a slac machine. Note that if you use a  shared slac machine Iíve seen those sometimes be very slow depending on load.


ok. Since for me it's using just the 22% (while until yesterday it was completely filling the core) I will try to reboot my machine, first thing. Tomorrow, as I want at least one run to be finished to compare results, and it started this morning and still runs. Well, runs... I'd say, walks (lame) ;-)
thanks

When you says it ďdoes moreĒ you mean it takes more time? Or do you see it doing something else?

Iím looking into it.

I cannot tell if it's writing more on the slcio file as long as the run isn't finished and I can compare full run sizes. The gbl file dimension looks comparable to the old one (for 1/3 of processed events).
So, actually I don't know it it's doing more. For sure, it's doing it more slowly...
can any of you try on your machines if experiences the same slowdown?
thanks.

yes
how do I know which strategies are running??
I just need what was running for pass2, but it looks like the reconstruction it's doing much more now... and it takes forever

Hi all,
after a fresh update yesterday I realized that the reconstruction speed decreased awfully: yesterday I was reconstructing 1000 events in 25 seconds, now it takes more than 3 minutes. Also, while before 100% of the cpu was taken, now not more than 25% is used (and I'm not doing anything else on the pc). The steering file I am using is EngineeringRun2015FullReconGbl2.lcsim with GhostHits removed, the "well-behaving" code (whose version number of course I lost after the last update) was next-to-last updated after the start of pass2 production, no later than one week ago.

What happened in the meanwhile?
thanks,
Alessandra
