              <div dir="ltr">I should start out by saying that I am
                extremely new to anything HPC.  Our end users purchased
                a 20 node cluster which a vendor set up for us with
                Bright/Slurm.
                <div><br>
                </div>
                <div>After our vendor said everything was complete and
                  we started migrating our users workflow to the new
                  cluster they discovered that they can't run more than
                  1 job per node at a time.  We started researching
                  enabling consumable resources which I believe we've
                  done so however we're getting the same result. </div>
                <div><br>
                </div>
                <div>I've just discovered today that both <b>scontrol
                    show node</b> and <b>sinfo -lNe</b> show that each
                  of our nodes have 1 CPU.  I'm guessing that's why we
                  can't submit more than 1 job at a time.  I'm trying to
                  determine where is it getting this information and how
                  can I get it to display the correct CPU information.</div>
