**4.2 Local Scheduler**

Each WN is provided with a Local Scheduler, developed in Java, that checks contents of its input folder: every time a new job file is detected it executes the task. In order to be recognized the filename must follow a predefined naming convention rules. During the execution the analyzed block is transformed into a Method of Moments (MOM) matrix. If the execution terminates successfully, the output is sent to the Master Node, that reassembles it with the outputs received from other nodes. Also the LS is in charge of tracking the status of job execution and sends information about start and stop time of each process.
