    Abstract: A system, method, and computer program product are provided for shading primitive fragments. A target buffer may be recast when shaded samples that are covered by a primitive fragment are generated at a first shading rate using a first sampling mode, the shaded samples are stored in the target buffer that is associated with the first sampling mode and the first shading rate, a second sampling mode is determined, and the target buffer is associated with the second sampling mode. A sampling mode and/or shading rate may be changed for a primitive. A primitive fragment that is associated with a first sampling mode and a first shading rate is received and a second sampling mode is determined for the primitive fragment. Shaded samples corresponding to the primitive fragment are generated, at a second shading rate, using the second sampling mode and the shaded samples are stored in a target buffer.

    Abstract: A method for rendering graphics frames allocates rendering work to multiple graphics processing units (GPUs) that are configured to allow access to pages of data stored in locally attached memory of a peer GPU. The method includes the steps of generating, by a first GPU coupled to a first memory circuit, one or more first memory access requests to render a first primitive for a first frame, where at least one of the first memory access requests targets a first page of data that physically resides within a second memory circuit coupled to a second GPU. The first GPU requests the first page of data through a first data link coupling the first GPU to the second GPU and a register circuit within the first GPU accumulates an access request count for the first page of data. The first GPU notifies a driver that the access request count has reached a specified threshold.
