In conclusion, the only way to do this is to create a file of desired size (dd from dev/zero) and then use mmap to back the memory-consuming processes with this file, rather than leaving it to the ...

Thanks, that is what is odd though: macOS is supposed to use virtual memory until there is free space in disc, and on my disk there are still hundreds of GBs available as it is an almost empty 500G...

Thank you, it is python 3.12 and gurobipy12.03 all in a conda environment. Your script gets killed by zsh at about 9GB of (compressed) virtual memory occupied (the parameter I=438 at this point). D...

Thank you for your reply, I tested what you propose. The odd thing is that when I run model.optimize() with model.Params.DualReductions = 0, the RAM usage is not that much different from the defaul...

Thank you for your reply, I understand. Is this additional optimisation step equivalent to m.optimize() with a conditional on the parameter m.Status or is it a different routine? I wonder if it is ...

Dear Jaromil,thank you for addressing all my questions. They were of general character, not just related to a specific model, which I referenced only as an example, so uploading it will not be nece...
