These are the two black holes moving counterclockwise in the x-y plane. If you use an aspect ratio of 1:1, then you'll see that they haven't actually moved very far yet. You also see that the black holes start at rest (in terms of coordinate speed) because the gauge conditions in the initial conditions is suboptimal in puncture initial conditions. If you zoom in onto one of the black holes you'll see that they don't move in straight lines, but rather on a circle with a radius of about 6.<div><br></div><div>You should, of course, be able to run this setup on 128 cores instead of just 8, where it would run faster. This is likely a problem with either you *.ini, *.sub, or *.run file. If you tell us more about your cluster (maybe point to its documentation) and share the respective Simfactory files, then we might be able to help out. Unfortunately, many HPC systems are designed to be different in their details from other systems, and thus setting up correct Simfactory files for a new cluster is difficult.
