How to reduce memory usage by the solver?
We have a large model and it ran out of memory when it is starting concurrent solve with dual and barrier method. So is it possible to just pick one method here to reduce the memory requirement? Than...
You can use the -d flag to use only dual simplex or the -b flag to use only the barrier algorithm for the root node.
On a related note, it seems like the presolver managed to remove a large portion of the problem. This suggests that the model could probably be improved, so the initial model isn't as large.
