The antenna may include a plurality of selectively connectable MEMS conductive sections and a plurality of fixed-length conductive section.

Abstract: A method and device for facilitating execution of tasks of a parallel job is disclosed. Parallel jobs comprise multiple tasks that can be executed in parallel by separate resources to produce an exit status for each task.

At commencement of a task, the task starter sends the host and process identifier to the resource manager. At completion of the task, the task starters collect the exit status of the task from the associated resource and send the exit status of the task back to the resource manager. An external event unit associated with the resource manager receives the process identifier and exit status of the tasks from the task starter.
