I am running this example using command

python3 run.py --np 2 --protocol prepace --prepace_bcl 500 --prebeats 4 --visualize

With this example, there should be two igb files generated, one is "vm_prepace.igb", and the other one is "vm_last_beat.igb". However, I found that the example only generated one igb file, which is "vm_prepace.igb". Not really understand why is this happening, could anyone help me with this? Thank you.

It seems that your experiment terminated prematurely. For more details, the logs would be required.

Primary job  terminated normally, but 1 process returned
a non-zero exit code. Per user-direction, the job has been aborted.
--------------------------------------------------------------------------
--------------------------------------------------------------------------
mpiexec detected that one or more processes exited with non-zero status, thus causing
the job to be terminated. The first process to do so was:

  Process name: [[26656,1],1]
  Exit code:    1
