Abstract
Embodiments relate to confidence threshold-based opposing path execution for branch prediction. An aspect includes determining a branch prediction for a first branch instruction that is encountered during execution of a first thread, wherein the branch prediction indicates a primary path and an opposing path for the first branch instruction. Another aspect includes executing the primary path by the first thread. Another aspect includes determining a confidence of the branch prediction and comparing the confidence of the branch prediction to a confidence threshold. Yet another aspect includes, based on the confidence of the branch prediction being less than the confidence threshold, starting a second thread that executes the opposing path of the first branch instruction, wherein the second thread is executed in parallel with the first thread.
