    <p>If your ini file is not part of the simfactory checkout (i.e. we
      don't know about it), you may have to edit by hand. I think
      simfactory attempts to run lscpu to determine some of these
      parameters, but if it is not present 1 may be the default.</p>
    <p>If you are part of a group, it may be beneficial to have your ini
      file checked in to simafactory (after it is debugged and tested)
      so that other members of your group have access to it. We can help
      make that happen.<br>

        <div>I am trying to run the static_tov simulation on my

        <div>I am assuming this is due to the <i>#Source tree
            management</i> module in the
          Cactus/simfactory/mdb/machines/<host>.ini file. In my
          case, the automatic *.ini file I got has these configuration:</div>

        <div>However, the machine I use has 24 cores for each node, and
          the number of threads for each core is 1. That means if I run
          the simulation using 48 cores, I need 2 nodes.</div>
        <div><br>
        </div>
        <div>Although I didn't get 2 hosts successfully(I got only 1), I
          am wondering if I have to edit the <host>.ini file after
          the command ./simfactory/bin/sim setup-silent by hand, for
          example: num-threads=1, nodes=2? Or is there any other correct
          way for getting more than 1 node? </div>
        <div><br>
        </div>
        <div>I would be appreciate it if you could give me some ideas on
          this problem.</div>
