title: H2O cluster uneven distribution of performance usage
body: <p>I set up a cluster with a 4 core (2GHz) and a 16 core (1.8GHz) virtual machine. The creation and connection to the cluster works without problems. But now I want to do some deep learning on the cluster, where I see an uneven distribution for the performance usage of those two virtual machines. The one with 4 cores is always at 100% CPU usage while the 16 core machine is idle most of the time.</p>
  
  <p>Do I have to make additional configuration during the cluster generation? Because it is odd for me that the stronger machine of the two is idle while the weaker one does all the work.</p>
  
  <p>Best regards,
  Markus</p>
