    Gurobi uses all threads available on the machine, unless parameter Threads is set explicitly by the user. Usually, also hyperthreading is exploited by Gurobi unless there is some specific OS setting preventing this.

    It is important to limit the number of Threads used by Gurobi when running multiple jobs on 1 machine to avoid interference of solutions processes.

    Note that using an excessive amount of threads is not always best, cf. Does using more threads make Gurobi faster?

    Best regards,
