  • Using ConcurrentMIP


    Hello. Since it took quite a long time to solve a model on a 4-core machine (one week), I also started it on a 24-core machine and set the ConcurrentMIP parameter to 4. Apart from the time advantag...

  • Submitting a Distributed MIP as a Batch Job


    Hi. Running distributed algorithms requires distributed workers and a manager. To setup the worker nodes you need to run "grb_rs --worker" on the worker nodes. If you are using an HPC cluster where...

  • Branch-and-Bound integer/float


    Hi. Gurobi is using the branch-and-bound/cut-method for optimization. According to literature the aim of this method is to find an optimal integer solution by going through the search tree. But the...

  • Using Windows/Linux


    Hello. Gurobi needs about 5 hours to solve a MIP model on a 6-core-machine on Windows. On a cluster (6 cores, Linux) the same model takes about 33 hours until its done. Furthermore, an easier MIP-m...

  • Calculating on Multiple Cores


    Hello everybody. I have got a MIP model that takes Gurobi 9 days to solve on 4 cores on a 24-core-machine it is still running after 10 days What is going wrong?
