I have a Dell running 2 Platinum 8160 Xeons and 720GB ecc memory with a Nvidia 3090 24 GB video card and 3D slicer crashes on a large file with 300 Gb of memory remaining - error says that there isn’t enough memory. Is there a max addressable limit for memory?
You’ll need to provide more details on what you were trying to accomplish.
I have a CT scan 90 micron per scan 7.7 Gb file. I have segmented the scan and when I try to create another island, I get an “out of memory” and you might fix it with increasing swap and ram.
I have a snippet of code in my .slicerrc.py file that would set the number of undo levels (which I think is defaulted to 10), I sometimes set it to 1 (or 0 if I’m feeling lucky). I don’t have it handy at the moment, but this may be something to try. I work with volumes larger than this on a machine with 128GB of ram and a 16GB NVIDIA RTX A5000, so you should be fine.
