Abstract: Apparatus and method for stack access throttling for synchronous ray tracing. For example, one embodiment of an apparatus comprises: ray tracing acceleration hardware to manage active ray tracing stack allocations to ensure that a size of the active ray tracing stack allocations remains within a threshold; and an execution unit to execute a thread to explicitly request a new ray tracing stack allocation from the ray tracing acceleration hardware, the ray tracing acceleration hardware to permit the new ray tracing stack allocation if the size of the active ray tracing stack allocations will remain within the threshold after permitting the new ray tracing stack allocation.

Abstract: Methods and apparatus relating to scalar core integration in a graphics processor. In an example, an apparatus comprises a processor to receive a set of workload instructions for a graphics workload from a host complex, determine a first subset of operations in the set of operations that is suitable for execution by a scalar processor complex of the graphics processing device and a second subset of operations in the set of operations that is suitable for execution by a vector processor complex of the graphics processing device, assign the first subset of operations to the scalar processor complex for execution to generate a first set of outputs, assign the second subset of operations to the vector processor complex for execution to generate a second set of outputs. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to predictive page fault handling. In an example, an apparatus comprises a processor to receive a virtual address that triggered a page fault for a compute process, check a virtual memory space for a virtual memory allocation for the compute process that triggered the page fault and manage the page fault according to one of a first protocol in response to a determination that the virtual address that triggered the page fault is a last page in the virtual memory allocation for the compute process, or a second protocol in response to a determination that the virtual address that triggered the page fault is not a last page in the virtual memory allocation for the compute process. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to transactional page fault handling. In an example, an apparatus comprises a processor to divide an execution thread of a graphics workload into a set of transactions which are to be executed atomically, initiate the execution of the thread, and manage the execution of the thread according to one of a first protocol in response to a determination that a page fault occurred in the execution of a transaction, or a second protocol in response to a determination that a page fault did not occur in the execution of a transaction. Other embodiments are also disclosed and claimed.

Abstract: A processing apparatus is described. The apparatus includes a graphics processing unit (GPU), including a register file having a plurality of channels to store data and an execution unit to examine data at each of the plurality of channels, read a data value from a first of the plurality of channels upon a determination that each of the plurality of channels has the same data and execute a single input multi data (SIMD) instruction based on the data value.
