Hi,
I’m trying to use o2-sim tools to go up to the reconstruction. I found the documentation about o2-sim in AliceO2/doc/DetectorSimulation.md (the part about o2-sim-digitizer-workflow is blank though) and about o2-tpc-reco-workflow in AliceO2/Detectors/TPC/workflow/Readme.md
I am having some issues in the process.
I am running this on an installation of O2 done with Alidock on a macOS Mojave machine.
Here are the command lines I enter.
-
o2-sim -n 5 -g pythia8 -e TGeant4 -m TPC,ITS
Here the process seems to go without issue. I only get a warning about LLVM symbols being “exposed” to CLING (see log_o2-sim.txt attached).
-
o2-sim-digitizer-workflow -b
Here, again, the process seems to work fine. I do not get any error message apart from the same LLVM symbol warning. One thing though, unless what is announced in AliceO2/Detectors/TPC/workflow at dev · AliceO2Group/AliceO2 · GitHub , I do not get any tpcdigits.root output.
Again, I attached a log in log_o2-digitizer.txt
-
o2-tpc-reco-workflow -b
This time, though the executable seems to start fine, it soon comes to a halt after
[11233:tpc-tracker]: [12:02:13][INFO] DEVICE: Running...
with the following error message appearing every minute, with an updated time:
[11157:internal-dpl-clock]: [12:03:13][INFO] from_internal-dpl-clock_to_tpc-digit-reader[0]: in: 0 (0 MB) out: 0 (0 MB)

[11233:tpc-tracker]: [12:03:13][INFO] from_tpc-tracker_to_tpc-track-writer[0]: in: 0 (0 MB) out: 0 (0 MB)
At this point it continues giving me these few lines every minute, and nothing is done, until I stop the process. Again, I attached a log in log_o2-tpc-reco-workflow.txt
I suspect the previous step, “o2-sim-digitizer-workflow -b”, doesn’t actually gives me the right outputs.
Anyone has an idea of what I am doing wrong?
Best wishes,
Aimeric
