    Abstract: A method, system, and computer program product are provided for prioritizing transactions. A processor in a computing environment initiates the execution of a transaction. The processor includes a transactional core, and the execution of the transaction is performed by the transactional core. The processor obtains concurrent with the execution of the transaction by the transactional core, an indication of a conflict between the transaction and at least one other transaction being executed by an additional core in the computing environment. The processor determines if the transactional core includes an indicator and based on determining that the transactional core includes an indicator, the processor ignores the conflict and utilizing the transactional core to complete executing the transaction.

    Abstract: A transactional memory system salvages a partially executed hardware transaction. A processor of the transactional memory system determines information about an about-to-fail handler for transactional execution of a code region of a hardware transaction. The processor saves state information of the hardware transaction, the state information usable to determine whether the hardware transaction is to be salvaged or to be aborted. The processor detects an about-to-fail condition during the transactional execution of the hardware transaction. The processor, based on the detecting, executes the about-to-fail handler using the information about the about-to-fail handler, the about-to-fail handler determining whether the hardware transaction is to be salvaged or to be aborted.
