Hi!
A few updates on this issue.
I made some tests and I was able to reduce the options of were the leak is happening.
I tested version 3.02.00 and version 3.04.00. They all have the same memory leak. I also tested to see if the problem is only in gevgen_atmo or gevgen also has it. And yes, both have it.
Finally, I decided to test different xsection tunes. I found out that if I use the G18_02a_00_000 tune, there is no leak. So it seems the leak is in some function used to calculate the G18_10a_02_11a tune.
I reduced the command that the leak can be reproduced,
gevgen -n 100000 -p 12 -t 1000080160 -e 1.0 --cross-sections O16_xsec_G18_10a_02_11a.xml --tune G18_10a_02_11a
Some information that might be relevant and I didn't include in the previous message.
The number of events that uses up all my memory is around 50k (which uses around 15 Gb of ram).
Requirements' versions:
log4cpp 1.1.4 LHAPDF 6.5.4 Pythia 6.428 Root 6.28/06
If you need more information, please let me know,
best,
Thanks Pedro. That's useful diagnostic information. We will try to follow up on this.
Dear GENIE developers,
I tried to run GENIE version 3.02.02's gevgen_atmo and it used up all my ram memory (see image attached).
Is it possible that there is a memory leak? If so, is it an issue with the 3.02.02 version or I is present in other versions?
I run the gevgen_atmo with the following configuration:
FLUX=./kam-nu-20-12-mtn-n3650.d GEOMETRY=./HyperKamiokande.root XSECS=./O16_and_H1_xsec.xml TIME=315360000 ENERGIES=0.1,1.0 LENGTH=m DENSITY=g_cm3 OUTPUT=HK_atm_bkg DETECTORPART=Fiducial
gevgen_atmo -f HAKKM:$FLUX[14],$FLUX[12],$FLUX[-14],$FLUX[-12] -r 1 -g $GEOMETRY -t $DETECTORPART -L $LENGTH -D $DENSITY -T $TIME -E $ENERGIES -o $OUTPUT --cross-sections $XSECS --tune G18_10a_02_11a
The table kam-nu-20-12-mtn-n3650.d was obtained from Honda's website (SK with montain max solar cicle) and I obtained O16_and_H1_xsec.xml from the pre-computed xsec using the provided reduce_gxspl.awk file.
I constructed HyperKamiokande.root using a simple root script, which I can share if needed.
