Abstract: Task graph control techniques for data transfer are described. The task graph control techniques are usable to aggregate data from multiple tasks into an aggregated data transfer, thereby improving operational efficiency and device performance. In a first example, a runtime scheduler executed on a command processor is implemented to select a node during execution of tasks of the task graph. The selected node is assigned by the runtime schedule to transfer aggregated data from that node and parent of that node. In a second example, a compiler of a host device is tasked with generating the task graph. As part of generating the task graph, the compiler also inserts one or more data transfer nodes. The location of the data transfer node within the task graph by the compiler is used to specify when a data transfer is to be performed.

Abstract: A technique for performing inside/outside testing is provided. To determine if a ray intersects a convex polygon, an inside/outside test is commonly performed by checking which side of an edge the ray passes. By efficiently sharing edge test results among polygons with shared edges, inside/outside testing for groups of polygons can be made more efficient. This optimization can be achieved using either full precision floating-point math or reduced precision (e.g., fixed-point math) to make hardware-based testing more cost-effective.

Various other methods, systems, and computer-readable media are also disclosed.

Abstract: A buffer of a processing system allows younger stores to write to a data cache before an older store completes its write operation to the data cache while maintaining the appearance of committing stores in program order. To maintain the appearance that a blocked store completed its write operation to the data cache, the processing system cancels the blocked store while “locking” the cache line in the data cache in an exclusive state to which the blocked store is attempting to write. The data cache negatively acknowledges any probes to the cache line until the blocked store has completed the write operation. The buffer thus decouples completing the write operation from global observability of the write operation.

Abstract: A system and method for providing automatic interactive access to headless cluster managers by combining two different resource managers with different capabilities. Hybrid cluster deployments are created, and interactive access is automatically provided to headless cluster managers by using one framework, which supports interactive access, to access the other framework, which does not natively support interactive access. A client in a first framework may create a secure connection from the first framework to a node in a second framework and then pass interactive users requests such as requests for data from storage through the first framework and the secure connection to the node in the second framework, which can access storage.

Abstract: Embodiments herein describe creating multiple packet fragments from a large data chunk that, for example, exceeds a maximum transmission unit (MTU) supported by a network. In one embodiment, a network interface controller or card (NIC) receives a direct memory access (DMA) from a connected host to transmit an IP packet or data using remote direct memory access (RDMA) technologies. The NIC can evaluate the data chunk associated with the DMA request and determine whether it exceeds the MTU for the network. Assuming it does, the NIC determines how many fragments to divide the data chunk into, and can fragment any portion of the data at flexible packet/payload offsets. The NIC can then retrieve the data chunk from host memory fragment-by-fragment, rather than reading the data chunk all at once, generating headers for the fragments, and then transmit them as packet fragments.

Abstract: A processing system executes a specialized wavefront, referred to as a “garbage collecting wavefront” or GCWF, to identify and deallocate resources such as, for example, scalar registers, vector registers, and local data share space, that are no longer being used by wavefronts of a workgroup executing at the processing system (i.e., dead resources). In some embodiments, the GCWF is programmed to have compiler information regarding the resource requirements of the other wavefronts of the workgroup and specifies the program counter after which there will be a permanent drop in resource requirements for the other wavefronts. In other embodiments, the standard compute wavefronts signal the GCWF when they have completed using resources. The GCWF sends a command to deallocate the dead resources so the dead resources can be made available for additional wavefronts.
