Abstract: The disclosed concepts provide a method to generate and use a compound shader object. A compound shader object includes a shader's intermediate representation (IR) and one or more binary modules; each binary module configured to execute on one type of graphics processing unit (GPU) with a specific input state. One method includes receiving, through a public application programming interface (API), a request to execute a shader from an user-level application. At the framework level, if the request corresponds to one of the prior compiled binary modules, that module may be passed to a GPU for immediate execution via a system private interface. If the request does not correspond to one of the binary modules, the shader's IR module may returned to the requesting user-level application (which module would then have to be compiled before it may be sent to the GPU).

Abstract: A safety parapet system for securement to the wall surfaces of building structures and which can be disposed on uneven ground that may surround the building structures includes at least two stanchions located adjacent the wall structure with each stanchion capable of receiving a drop-in safety rail post that is telescopically adjustable along the length of the stanchion for locking into place with the safety rail posts being independently adjustable on the stanchions so that a walkway can be supported in a horizontal disposition on laterally extending members of each safety rail post whether the safety parapet system is disposed on level or uneven ground. An optional handrail can be mounted to the safety rail posts for use if the worker is located six feet or more above the ground surface.
