Abstract: A request from a client to perform a task is received. The client has a predetermined limit of compute resources. The task is dispatched from a batch scheduler to a compute node as a non-speculative task if a quantity of compute resources is available at the compute node to process the task, and the quantity of compute resources in addition to a total quantity of compute resources being utilized by the client is less than or equal to the predetermined limit, such that the non-speculative task is processed without being preempted by an additional task requested by an additional client. The task is dispatched, from the batch scheduler to the compute node, as a speculative task if the quantity of compute resources is available to process the task, and the quantity of compute resources in addition to the total quantity of compute resources is greater than the predetermined limit.

Abstract: Objects are modeled and rendered using multiple surfaces to provide attributes used in rendering. In some embodiments, a reference surface for an object is defined, e.g., using conventional modeling techniques. One or more auxiliary surfaces are associated with portions of the reference surface. Some of the surface attributes (e.g., color, surface normal, texture, lighting) are associated with the reference surface, while other attributes (e.g., transparency) are associated with the cards. To render an image, a ray associated with a pixel is traced to its intersection with the reference surface and to its intersection with one of the auxiliary surfaces. The attributes associated with the reference surface are determined based on the intersection point of the ray with the reference surface, and the attributes associated with the auxiliary surface are determined based on the intersection point of the ray with the auxiliary surface.

Abstract: A surface normal map of an object can be interactively modified to create brushstroke-like textures. In one embodiment, surface normal components along the x, y, and z axes (in object coordinate space) are mapped onto red, green, and blue color components. The object's surface is displayed in an editing interface (e.g., a painting program) with colors indicating the surface normals. The user can then modify the surface normals to achieve a desired look for the object. The modified surface normals are stored with the object-model data and are used in rendering the object, helping to create a painted appearance.
