Randomness

[thnam]

Looking at the output from one bg4sim, I was kind of worried because of the regularity(?) of the file size:

-rwxrwxr-x. 1 nam nam    1269 Sep  5 00:56 sim_GeCal_Si16p_target_34cm_run1_7.txt.boss
drwxrwxr-x. 6 nam nam    4096 Sep  5 00:56 configure
drwxrwxr-x. 3 nam nam    4096 Sep  5 00:56 macros
-rw-r--r--. 1 nam nam 2066614 Sep  5 01:12 2_job0.raw
-rw-r--r--. 1 nam nam 2066613 Sep  5 01:12 5_job0.raw
-rw-r--r--. 1 nam nam 2066615 Sep  5 01:12 0_job0.raw
-rw-r--r--. 1 nam nam 2066613 Sep  5 01:12 4_job0.raw

Then I compared the histograms from these output files (histogram h01 means subrun 1 of job 0, ...):

It is clear that all subruns in one job give the same result ...
I tried another run, to confirm this:

bg4sim_sub -t sim -b 0 -e 7 -Y GeCallibration Randomness_check

The result looks similar:

[nam@ana2 scripts]$ ll ../output/Randomness_check/

-rw-r--r--. 1 nam nam 143779 Sep  6 10:57 0_job2.raw

The conclusion is that all subruns are the same!!!
I will check why it is the case.

Hi Nam, Can you post the configure files and macros? I want to have a check.
I use bg4sim_sub to generate different random seeds for different jobs. In principle we shouldn't get this regularity...

Hi Chen,
I was using the GeCallibration script in the alcap-org/commit@8ad84a8c2216e708

bg4sim_sub -t sim -b 0 -e 7 -Y GeCallibration Randomness_check
