[Gate-users] Jobs killed "memory exceeded"?

[JAN Sebastien]

Hi Amy,
As explained by Marc, this is a memory leak...probably du to the fact that the energy of optical photons which are generated is out of the range defined in the xml files (material & surface). Try to correct that point and fell free to tell us if the problem is solved.
Cheers
Sebastien

Hi Amy,

Perhaps there is a memory leak? If there is, it's gonna be very annoying for you to troubleshoot if you have no C++ experience.

I'd suggest you look at using Valgrind to detect memory leaks. You can find Valgrind here: http://valgrind.org

The Quick Start page should help you run it. Feel free to post the output to the mailing list or send it to me and I'll have a quick look.

Good luck!
Marc

Gate users,

I have been running simulations using optical photons that run to completion when I am using a beta source. However, when I change the source to an alpha source, suddenly all of my simulations only run for a few minutes before being killed. It seems like the memory usage skyrockets beyond some limit and get killed.

Why would changing only the source do this? Is there something I can do to stop this from happening? The simulation runs fine for a few particles, but I am not sure why it would behave like this.


Please help. Thank you,

Amy
