Abstract: Methods and systems for establishing user sessions between a client and a server or server farm can be carried out by a load balancing agent executing on a computer in communication with the client, server or server farm. The load balancing agent can intercept a connection request generated by an application executing on a client and responsively select a server on which to establish a user session. Selecting the server can be based on overbooking a particular server and choosing a server with a predetermined amount of forecasted load. Forecasted load can be determined by summing the current load on a server with a current load calculated by multiplying: the average load on the user sessions hosted by the server; by the number of cached user sessions stored on the server; and by the probability that a cached user session reconnects.

Abstract: Remote rendering of three-dimensional images using virtual machines includes using a hypervisor executing on a physical computer to allocate exclusive and direct access to a graphics processing unit in the physical computer, to a first virtual machine. An agent executing on a second virtual machine intercepts three-dimensional draw commands generated by a three-dimensional application and forwards the intercepted draw commands to a rendering agent executing on the first virtual machine. The rendering agent then transmits the intercepted draw commands to the graphics processing unit for rendering upon which the graphics processing unit renders a three-dimensional image from the draw commands. The rendering agent obtains the rendered image from the graphics processing unit and forwards the image to the second virtual machine. Upon receiving the rendered image, the second virtual machine transmits the rendered image to another remote, physical computer where the rendered image is displayed to a user.
