摘要： A method for partitioning executable operations for a reconfigurable computing system includes receiving a set of expressions comprising a plurality of operations and dependencies for those operations, partitioning the plurality of operations into selected executable partitions wherein each selected executable partition conforms to resource constraints for a reconfigurable unit of the reconfigurable computing system. Partitioning the plurality of operations into selected executable partitions may include seeding a candidate partition with an operation, recursively generating an additional candidate partition for each operation adjacent to the candidate partition whose dependent operations are already within the candidate partition or a previously selected partition, and selecting a best candidate partition based on resource cost. A corresponding system and computer-readable medium are also disclosed herein. The system includes a partitioning module that that partitions the plurality of operations into selected executable partitions according to the method describe above.

摘要： A processor comprises a microarchitectural feature and dynamic tuning unit (DTU) circuitry. The processor executes a program for first and second execution windows with the microarchitectural feature disabled and enabled, respectively. The DTU circuitry automatically determines whether the processor achieved worse performance in the second execution window. In response to determining that the processor achieved worse performance in the second execution window, the DTU circuitry updates a usefulness state for a selected address of the program to denote worse performance. In response to multiple consecutive determinations that the processor achieved worse performance with the microarchitectural feature enabled, the DTU circuitry automatically updates the usefulness state to denote a confirmed bad state. In response to the usefulness state denoting the confirmed bad state, the DTU circuitry automatically disables the microarchitectural feature for the selected address for execution windows after the second execution window. Other embodiments are described and claimed.
