Abstract
When executed, a transaction-begin instruction specifies an initial value for a transaction-count-to-completion (CTC) value for a transaction. The initial value indicates a predicted duration of the transaction. The CTC value may be a number of instructions to completion or an amount of time to completion. The CTC value is adjusted as the transaction progresses. The adjusted CTC value indicates how far the transaction is from completion. When a disruptive event associated with inducing transactional aborts, such as an interrupt or a conflicting memory access, is identified while processing the transaction, processing of the disruptive event is deferred if the adjusted CTC value satisfies deferral criteria. If the adjusted CTC value does not satisfy deferral criteria, the transaction is aborted and the disruptive event is processed.
