Semiconductor light-emitting device and method for separating semiconductor light-emitting devices

The invention provides a method for separating semiconductor light-emitting devices formed on a substrate. In the method, a pulse laser beam having a pulse width less than 10 ps in a substrate is focused on the substrate, to thereby cause multi-photon absorption in the substrate. Through multi-photon absorption, a groove is formed through the pulse laser beam along a split line predetermined on a surface of the substrate, the groove being substantially continuous in the direction of the predetermined split line. In addition, internal structurally changed portions are formed through the pulse laser beam at a predetermined depth of the substrate on a predetermined split face, the structurally changed portions being discontinuous in the direction of the predetermined split line. Subsequently, an external force is applied to thereby form a split face along the continuous groove and the discontinuous internal structurally changed portions, whereby the semiconductor light-emitting devices are separated from one another

Load balancing in a system with multi-graphics processors and multi-display systems

In typical embodiments a three GPU configuration is provided comprising three discrete video cards, each connected to a standard monitor placed horizontally for a 3× horizontal resolution. In this configuration, depending on the load on each GPU, the vertical split lines are dynamically adjusted. To adjust the load balancing according to these virtual split lines, the rendering clip rectangle of each GPU is adjusted, in order to reduce the number of pixels rendered by the heavily loaded GPU. These split lines define the boundary of the scene to be rendered by each GPU, and, according to some embodiments, may be moved horizontally. Thus for example if a GPU has a more complex rendering clip polygon to render than the other GPUs, the neighboring GPUs may render the rendering clip polygon it displays plus a portion of the rendering clip polygon to be displayed by heavily loaded GPU. The assisting GPUs transmit to the heavily loaded GPU the portion of the rendering clip polygon to be displayed by GPU via the chipset with a peer-to-peer protocol or through a communication bus. The split line is dynamically adjusted after each scene.
