    Hi Kristy,

    I hope this reply is still relevant - please excuse the long delay!

    Sending multiple jobs to the Compute Server should not change the solver's path to optimality (given that no parameters have been changed). Every single job on the server will try to use all available cores and generate as many threads accordingly. Overloading the server usually leads to worse solving times because the OS on the server needs to juggle all those threads. That's why the default JOBLIMIT for parallel jobs is set to 2 to avoid this congestion and rather make use of the queueing mechanism of the Compute Server.

    Cheers,
    Matthias
