[Gate-users] Memory leak issue when using voxelized source/phantom

[David Boersma]

Dear Behzad Rezaeifar,


Please keep the conversation on the mailing list. Other users may have a similar issue and would like to see how this was resolved.


Thanks for the additional information. Which version of GATE are you using? Memory leaks are always bad, regardless of how they are caused. So I think that it would still be useful if you could provide us with a simplified mac file that reproduces the issue.


Thanks!

David

Dear David Boersma,

I managed to find the problem after going through every line of my simulation. I realized the issue isn't actually related to the voxelized geometry and the cause was attaching a phantomSD to it. I don't know if this is a bug or normal behaviour of Gate, but the memory leakage speed was related to the voxelized geometry and it's specification. Once I deleted the phantomSD line, the problem was solved.

Let me know if you still want me to report the problem on Github.

Kind regards,
Behzad Rezaeifar

Dear Behzad Rezaeifar,


Could you please create a minimal example Gate macro that demonstrates this memory leak issue? Before we can fix a problem we must first be able to reproduce it, and that is always much easier if you provide us with a concrete example.


And since this is going to be a bug report, you can post it as an "issue" on github. So go here:

https://github.com/OpenGATE/Gate/issues

and click on the green "New Issue" button.


Thanks!

Betreff: [Gate-users] Memory leak issue when using voxelized source/phantom

Dear Gaters,

I have noticed a serious memory leakage problem while running my simulations in Gate. I ran some tests and noticed that it might be related to voxelized phantom and source in my simulations. Specifically, when I add a voxelized source with user defined energy spectrum, the memory leak would be almost two times faster than when I have voxelized source with mono energy. In case of voxelized phantom the memory leak is almost 5 times faster than usual.

I would appreciate if someone can help me with this issue.

Kind regards,
