Abstract: In certain aspects, the invention features a system and method for receiving a parent job configured to produce one or more descendant jobs, and scheduling computation of the parent job on a node computing device that is one of a plurality of node computing devices of a distributed computing system. In such an aspect, the distributed computing system further includes a scheduler server configured to selectively reschedule computation of a job other than a parent job from any one of the plurality of node computing devices to another of the node computing devices. Such an aspect further includes preventing rescheduling of the parent job unless each of the descendant jobs is completed or terminated.

Abstract: A display device includes plural red, green, and blue pixels provided with current-driven type red-, green-, and blue-light-emitting elements, respectively. A method of driving the display device includes writing a video signal voltage into each of the pixels in a state in which all the light-emitting elements cease to emit light during a first portion of one frame period at a beginning thereof, and then operating a respective one of the light-emitting elements to emit light during at least one portion of the one frame period succeeding the first portion. Each of the at least one portion of the one frame period is determined by light emission characteristics of the respective one of the light-emitting elements, and also is determined by the video signal voltage of the respective one of the pixels.
