Example 61 with Scheduler

use of org.ow2.proactive.scheduler.common.Scheduler in project scheduling by ow2-proactive.

the class TaskLauncher method sendResultToScheduler.

    // recipient is the TaskTerminateNotification, an active object on the
    // scheduler side. If the scheduler experienced a transient failure
    // while the task was computing, then the reference to this
