I’m currently using `COSMO.jl` to do a large scale SDP with `JuMP` as the interface. Is it possible to store the status of model for example every 100000 iterations, and if `max_iter` is reached, to start from the starting status in the next run?

This is seemingly supported. See [here](https://jump.dev/JuMP.jl/stable/tutorials/conic/start_values/). You could try to play around with the given example and set, e.g., `max_iter = 50`. Then adapt the example to your problem accordingly.

Note: I have not tried this before.
