Full CPU utilization with python-MIP

[Manuel Parati]

Hi everyone,

I am using python-mip with CBC as a solver to find the optimal solution to a MIP problem on large instances. The problem is that it is too slow and looking at the CPU usage statistics I notice that the process uses only 13/14% of the CPU while the rest remains unused. I also tried adding model.threads = -1 but the CPU remains mostly unused. Is there any way to fully utilize the CPU?

I am using:

- Arch Linux latest version with linux kernel

- Python 3.10.4

- MIP 1.13.0

Hi.

I've also always been slow using CBC. I prefer to use the Gurobi solver. You can try Gurobi with an academic license.

Att,

Luciano
