Running analysis task in simfast macro [message #16852]

Hi all,

as discussed today in the meeting, Ralf and I just fixed the issue with adding the analysis task in the simfast_opt.C macro. Please update fsim and PndTools/AnalysisTools. The only thing you need to change in the Exec routine of the analysis task is to replace

  fAnalysis->GetEvent();  -->  fAnalysis->GetEventInTask();

and in order to switch off the output, change in simfast.C/simfast_opt.C

PndFastSim* fastSim = new PndFastSim();  -->  PndFastSim* fastSim = new PndFastSim(false);

(boolean parameter steers persistency) and everything should work as expected.

Best,
Klaus

Hi Klaus,

I think that the feature looks quite useful.
But still I am wondering one thing.
I am using PndScrutAnaTask which is needed to compile the code. because it would be faster than root script.
If I want to combine analysis task in fastsim, then I have to put below line into the simfast_opt.C with switch off option as you mentioned.

PndScrutAnaTask *scrutTask = new PndScrutAnaTask();
fRun->AddTask(scrutTask);

Is it correct way?

Have a nice weekend,
Donghee

Hi Donghee,

exactly. The structure of my macro looks like

  
  ...
  PndFastSim* fastSim = new PndFastSim(false);
        
  // ... lots of stuff
  
  fRun->AddTask(fastSim);
	
  PndScrutAnaTask *scrutTask = new PndScrutAnaTask(pbarmom, outfile);
  fRun->AddTask(scrutTask);
  
  fRun->Init();
  fRun->Run(nEvents);
  ...

Best,
Klaus

Hi,
I haver just tried with the latest trunk, I modified the fAnalysis->GetEventInTime, I wrote the PndScrutTask in the simfast_opt macro, together with the ForceField line. But the output file has still an empty tuple.
What I did wrong? or maybe you introduced the change only in the scrut?

Ok, my fault, now it works (I forgot to read the scrut folder in the macro cmakelist, and I was using an old library without the last changes).

However, at present we can skip the storage of fastsim TClonesArrays, but not the MCTrack TCLonesArray, with substantially no gain at all.
I asked Florian how to switch off the storage of MCTrack, let's see... maybe this will require a modification of the base packages.

Hi,

I also tried it using the PndScrutAnaTask and simfast_opt.C with the changes Klaus posted here. It works fine, but besides the (nicely small!) output file of the analysis task i get an output file of FastSim, which is about 180Mb/1Mio DPM events. I guess that is the MCTrack TClonesArrays Stefano mentioned...
Are there any news on the issue how to get rid of this output?

Best regards,
Malte

At present, the only think you can do is to change the PndStack and hardcode a kFALSE instead of a kTRUE:

MacBook-Pro-di-Stefano:run spataro$ svn diff ../../pnddata/PndStack.cxx 
Index: ../../pnddata/PndStack.cxx
===================================================================
--- ../../pnddata/PndStack.cxx	(revision 25514)
+++ ../../pnddata/PndStack.cxx	(working copy)
@@ -384,7 +384,7 @@
 
 // -----   Public method Register   ----------------------------------------
 void PndStack::Register() {
-  FairRootManager::Instance()->Register("MCTrack", "Stack", fTracks,kTRUE);
+  FairRootManager::Instance()->Register("MCTrack", "Stack", fTracks,kFALSE);
 }
 // -------------------------------------------------------------------------

Other changes need a modification of the base packages, which is something we cannot do directly and in a short time.

Hi Stefano,

i changed the line you suggested and ran the job again:

Now it crashes after several thousand events, leaving me with the following stacktrace:

Root > Function simfast_opt() busy flag cleared

Every time I run it, the crash occurs after a different number of events. This may be due to the fact that I cannot generate the _same_ events again, using exactly the same random seed (can I??).

How to deal with this error?

Best regards,
Malte

Hi Malte,

You need the following line in your macro:

        RhoCalculationTools::ForceConstantBz(20.0);

The reason is that FairRunAna would be required from RhoCalculationTools to get the magnetic field. However in simulation it tis FairRunSim.

Cheers
Ralf

However, if you put a gRandom->SetSeed(XXXXX), where XXXXX is your seed number, in theory you should be able to have exactly the same numbers from the simulation.
