Abstract: Systems, apparatuses, and methods for implementing continuation analysis tasks (CATs) are disclosed. In one embodiment, a system implements hardware acceleration of CATs to manage the dependencies and scheduling of an application composed of multiple tasks. In one embodiment, a continuation packet is referenced directly by a first task. When the first task completes, the first task enqueues a continuation packet on a first queue. The first task can specify on which queue to place the continuation packet. The agent responsible for the first queue dequeues and executes the continuation packet which invokes an analysis phase which is performed prior to determining which dependent tasks to enqueue. If it is determined during the analysis phase that a second task is now ready to be launched, the second task is enqueued on one of the queues. Then, an agent responsible for this queue dequeues and executes the second task.

Abstract: Systems, apparatuses, and methods for implementing a multi-kernel wavefront scheduler are disclosed. A system includes at least a parallel processor coupled to one or more memories, wherein the parallel processor includes a command processor and a plurality of compute units. The command processor launches multiple kernels for execution on the compute units. Each compute unit includes a multi-level scheduler for scheduling wavefronts from multiple kernels for execution on its execution units. A first level scheduler creates scheduling groups by grouping together wavefronts based on the priority of their kernels. Accordingly, wavefronts from kernels with the same priority are grouped together in the same scheduling group by the first level scheduler. Next, the first level scheduler selects, from a plurality of scheduling groups, the highest priority scheduling group for execution. Then, a second level scheduler schedules wavefronts for execution from the scheduling group selected by the first level scheduler.

Abstract: Systems, apparatuses, and methods for performing split-workgroup dispatch to multiple compute units are disclosed. A system includes at least a plurality of compute units, control logic, and a dispatch unit. The control logic monitors resource contention among the plurality of compute units and calculates a load-rating for each compute unit based on the resource contention. The dispatch unit receives workgroups for dispatch and determines how to dispatch workgroups to the plurality of compute units based on the calculated load-ratings. If a workgroup is unable to fit in a single compute unit based on the currently available resources of the compute units, the dispatch unit divides the workgroup into its individual wavefronts and dispatches wavefronts of the workgroup to different compute units. The dispatch unit determines how to dispatch the wavefronts to specific ones of the compute units based on the calculated load-ratings.

Abstract: Systems, apparatuses, and methods for converting computer program source code from a first high level language to a functionally equivalent executable program code. Source code in a first high level language is analyzed by a code compilation tool. In response to identifying a potential bank conflict in a multi-bank register file, operands of one or more instructions are remapped such that they map to different physical banks of the multi-bank register file. Identifying a potential bank conflict comprises one or more of identifying an intra-instruction bank conflict, an inter-instruction bank conflict, and identifying a multi-word operand with a potential bank conflict.

Abstract: The invention relates to a measuring apparatus comprising a coating probe and a probe holder which is disposed on a wall of a sample chamber. The coating probe is displaceable into the sample chamber on one side and is displaceable out from the sample chamber on the opposite side. As a result, practical investigations of boiler coatings are made possible.
