I have tried the every methods in How do I avoid an out-of-memory condition? – Gurobi Support Portal and change the parameters as possible as I can,but there is still out of Memory issue. Is it possible to find some clue in the log? It is very grateful to get any suggestion.

  It looks like you cannot avoid running out of memory on the particular machine you are using for this particular model even through additional parameters. From here, I see 2 options.

  1. You should switch to a bigger machine. You could try the Gurobi Cloud to offload the computing to another machine that has more memory.

  2. Your model has extremely many rows compared to the number of columns. Are you sure that all constraints are necessary to define the model appropriately? You could try to detect and remove constraints which are not necessary to reduce the size of your model. You could consider using lazy constraints to avoid adding all constraints at once to your model.

  Could you share your model as described in Posting to the Community Forum? Maybe there is something that can be improved on our side.

  Best regards,
