[Gate-users] *** Break *** segmentation violation

[Mijat Paunovic]

Dear Gate Community,
I am using HTCondor to run Gate on Docker on a 32 CPU machine. I am
simulating a simple CT scanner with a monoenergetic X-ray source and a
cylindrical fantom. I wrote a bash script in which each iteration
represents one angle of rotation of a cylindrical phantom. In total, I am
running 90 iterations for 90 angles of rotation, and in each iteration,
HTCondor splits my Gate script on 32 parts.
Running the simulation for low number of histories worked fine up until
10^6 histories per HTCondor job. Once I went to 10^7, I get a **** Break
*** segmentation violation *error which I noticed was already addressed but
as I understood, not for the same reason in:
http://lists.opengatecollaboration.org/pipermail/gate-users/2019-January/010673.html
.
I am using a Gate:9.0 image of Gate on DockerHub.
I checked multiple times and the only thing that I found was causing the
error was the increase in the number of histories *per job*. Here is the
complete error report:
