Dear all,
I had set up a simulation where neutrons pass through
different media and strike a 10B target, producing
7LI and 4He. These charged particles enter a gas
and the energy deposited is scored. I had started with 9E+03 incident
neutrons,
and evertything seemed to work fine. When I tried to get more statistics, a
problem
showed up and I do not understand where it comes from.
The run is aborted more than one hour after it started running (at least on
the server I am using)
In the *.err file, here and there, the meassage
Stepop, Pla < Pthrij!! ij, mmat, ekin, Pla, Pthrij
appears and in the *.log file the following message is given
Program received signal SIGFPE: Floating-point exception - erroneous
arithmetic operation.
Backtrace for this error:
#0 0x2BA5DDB6DF37

I am running the simulation on a server 64 bits
(uname -a
Linux dapint 2.6.18-194.11.4.el5 #1 SMP Tue Sep 21 06:46:41 EDT 2010 x86_64
x86_64 x86_64 GNU/Linux)
The ROOT version is 5.18/00 and fluka version fluka2011.2-linux-gfor64bit-
gcc451-AA.tar.gz
The variables FLUFOR and GFORFLU are set to
setenv FLUFOR gfortran
setenv GFORFLU mio-gfortran
with gfortran -v : gcc version 4.1.2 (GCC)
and mio-gfortran -v:gcc version 4.5.1 (GCC)
Could anyone give a look and help me, please?
Thank you,
best regards,
Francesca
