ray simulations seem to work

nodes (except head node) can deconnect and reconnect to/from the cluster and work is rebalanced properly. if a node dies while simulating, the leftover work is picked up at the end and everything is merged normall. Tests of the actual validity of the mergd data have not been made yet
