    Thank you! Before, I thought you were going to tell me that another job scheduling system would be better for this, which kind of confused me. But now it's clear.

  • Tessa Meyer commented,

    Ahh, ok. Basically, however, the batch solve command does not work with any job scheduling system for Linux clusters, regardless of which one it is.

  • Tessa Meyer commented,

    Hey. One last question: However, you can use slurm and/or screen to work with a batch equivalent. What difference would using slurm instead of lsf make?

  • Tessa Meyer commented,

    Hi JaromiƂ. Just to make sure I have got you correctly: With an academic license, I can not submit a distributed MIP as a batch (lsf) using the batch solve command? Kind regards Tessa

    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

    Answered

    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...

    I am using the energy modelling framework oemof which uses the framework pyomo itsself. Providing the path and setting the output flag does not make it write the logfile. So there might be some iss...

  • Tessa Meyer commented,

    Hi Sonja. Actually, I can not directly interact with gurobi as there is an other framework in between. So to write the logfile I passed the parameter 'LogFile' (the same way I passed the parameters...

    Using Windows/Linux

    Completed

    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...

    Hi. Okay. I also have another model that takes about 5 hours on a 4-core-workstation. On a cluster (24-core-machine) it is still running after 20 hours using 40 GB RAM on average. Gurobi "is design...
