NON-REPRODUCIBILITY PROBLEM OF A GPAMELA RUN FIXED. |
34 |
|
The non-reproducibility of a GPAMELA run was due to the random number |
35 |
|
initialization in the GARFIELD code. In GARFIELD by default, the initial |
36 |
|
seeds of the random number generators are always the same while the random |
37 |
|
number generators are called a given number of times (determined by the |
38 |
|
hour of the day) during the initialization phase (see init.f subroutine in |
39 |
|
the GARFIELD code for details). Follows that different runs produce |
40 |
|
different results without changing the initial seeds. To have identical |
41 |
|
results in different runs, the GARFIELD program has to start typing the |
42 |
|
noRNDM_initialisation switch. To avoid of specifying this switch by the user, |
43 |
|
the GARFIELD package has been upgraded with a patch. In this way the problem |
44 |
|
is partially solved because, now, the initial seeds of the random generators |
45 |
|
in GARFIELD will be always the same even if the RNDM GEANT data card is |
46 |
|
activated by the user for changing the initial seeds in the GPAMELA program. |
47 |
|
Work is in progress for a more general correction of this problem. |
48 |
|
Please, use the updated GARFIELD code released with the CVS version v4r1 |
49 |
|
to fix this problem. |

RNDM ROUTINE REPLACED BY THE GRNDM ROUTINE IN GPXTR AND NPOISS. |
53 |
|
The obsolete RNDM random number generator has been replaced by the GEANT |
54 |
|
GRNDN routine in the gpxtr.F subroutine and in the npoiss.F function. |
55 |
|
|
56 |
|
BUG FOUND AND FIXED: the set and detector calorimeter addresses (ISCAL |
57 |
|
and IDCASI variables) used in GUTREV were respectively set to a fixed |
58 |
|
values of 12 and 1. The correct values of these variables are stored in |
59 |
|
the GPSED common when the set and the detector ZEBRA banks are filled |
60 |
|
during a run. In general the values of the set and detector addresses |
61 |
|
depend on the number of active detectors in a given run. ISCAL=12 and |
62 |
|
IDCASI=1 are only right when all the detectors of GPAMELA are active. |
