Hi,
I simulated background with Geant 3 and DPM at 15GeV. I checked the log but just found an error in my pid log. The scripts are very similar like ones of the tutorial.

I got simlar errors in multiple jobs. I simulated 300 jobs each with 1500 events and got that error in 4 jobs. Another time I simulated 200 jobs each with 2000 events and also got that error in 4 jobs. I attached the full pid log for further information.

Greetings Simon

PS: running on sep12 externals and apr13 release

These are fortran problems with libraries, we cannot fix them. They appear seldom, in such cases the only thing to do is to rerun the macro. In theory it is fine just to rerun the pid, you don't need to start from sim.

Hi Simon,

this has to do with the fact that Geant3 was written as a 32bit program and the code was adapted to 64bit. The error you see has to do with this adaption. If the fortran/geant3/zebra memory manager detects an incorrect memory layout the program is terminated immediately. This is done to avoid crashes during runtime or even worse changing the transport results.

As Stefano pointed out you can easily run the same simulation again and you will not see any problems.

Ciao

Florian
