-A worker is a Java daemon that runs on the user machine. Assumed to be volatile, the workers reports periodically
-themselves to the coordinator, accept jobs, retrieve input, compute jobs, and store the results of the computation on warehouses. If the
-coordinator does not receive a signal from a worker, it will simply remove it from the scheduling list, and if a job had been assigned to that
-worker, it will be re-assigned to another one. A schema of the architecture is shown in Figure 4.
