Example 6 with ScriptException

use of org.ow2.proactive.scripting.ScriptException in project scheduling by ow2-proactive.

the class SchedulingMethodImpl method getRMNodes.

/**
 * Ask to the RM the given number of node resources.<br>
 * If there is a problem with these task selection (such as bad selectionScript) this method
 * will terminate the corresponding tasks and jobs. As the selection scripts contain errors, the task
 * and its surrounding jobs must be stopped.
 *
 * @param neededResourcesNumber the number of resources to ask for (must be &gt; 0).
 * @param tasksToSchedule the task to be scheduled
 * @return A nodeSet that contains at most 'neededResourcesNumber' available compatible resources.
 * 		   An empty nodeSet if no nodes could be found
 * 		   null if the their was an exception when asking for the nodes (ie : selection script has failed)
