Abstract: Ein Verfahren und ein Informationsverarbeitungssystem verwalten Lade- und Speichervorgangsoperationen, die in abweichender Reihenfolge ausgeführt werden. Es wird mindestens eine der folgenden Anweisungen ausgeführt: eine Ladevorgangsanweisung und eine Speichervorgangsanweisung. Es erfolgt eine Feststellung, dass eine Operand-Speichervorgang-Vergleich-Gefahr aufgetreten ist. Auf der Grundlage der Feststellung wird ein Eintrag in einer Tabelle zur Vorhersage von Operand-Speichervorgang-Vergleich-Gefahren erstellt. Der Eintrag umfasst mindestens eine Anweisungsadresse der Anweisung, die ausgeführt wurde, und ein Gefahrenanzeigeattribut, das der Anweisung zugeordnet ist. Das Gefahrenanzeigeattribut zeigt an, dass die Anweisung auf die Operand-Speichervorgang-Vergleich-Gefahr gestoßen ist. Wenn eine Ladevorgangsanweisung des Gefahrenanzeigeattributes zugeordnet ist, wird die Ladevorgangsanweisung von allen Speichervorgangsanweisungen abhängig, die einem im Wesentlichen gleichen Attribut zugeordnet sind.

Abstract: Execution of threads in a processor core is controlled. The processor core supports simultaneous multi-threading (SMT) such that there can be effectively multiple logical central processing units (CPUs) operating simultaneously on the same physical processor hardware. Each of these logical CPUs is considered a thread. In such a multi-threading environment, it may be desirous for one thread to stop other threads on the processor core from executing. This may be in response to running a critical sequence or other sequence that needs the processor core resources or is manipulating processor core resources in a way that other threads would interfere with its execution.

Abstract: Un método para controlar la ejecución de hilos en un entorno informático, comprendiendo dicho método: detener (604), mediante un hilo que se llevan a cabo en un procesador del entorno informático, la ejecución de otro hilo que se ejecuta dentro del procesador, usando la parada uno o más bits en uno o más registros compartidos del procesador, estando el uno o más registros compartidos por el hilo y el otro hilo, comprendiendo la parada: determinar si el otro hilo está prohibiendo su detención comprobando (600) un bit seleccionado en un registro de control, en donde el registro de control comprende un registro de dicho uno o más registros compartidos del procesador y un bit seleccionado en un registro de dirección de instrucción, en donde el registro de dirección de instrucción comprende un registro de uno o más registros del procesador únicos del otro hilo; detener, mediante el hilo, la búsqueda y ejecución de instrucción en el otro hilo, basándose en la etapa de determinación inmediatamente anterior que determina que el otro hilo no está prohibiendo su detención; determinar que el otro hilo ha dejado de ejecutarse dentro del procesador; y caracterizado por realizar (606), mediante el hilo, una operación de drenaje para todos los hilos en el entorno informático, en donde la operación de drenaje retiene la expedición de instrucción para el hilo hasta que todas las instrucciones del otro hilo se hayan drenado o evacuado, cuando la etapa de determinación inmediatamente anterior determina que el otro hilo ha dejado de ejecutarse dentro del procesador; realizar (618) mediante el hilo una o más operaciones dentro del procesador después de que la ejecución del otro hilo fue detenida dentro del procesador por el hilo; y basándose en la finalización de la una o más operaciones, permitir que (620) el otro hilo continúe ejecutándose dentro del procesador

Abstract: A method and information processing system manage load and store operations executed out-of-order. At least one of a load instruction and a store instruction is executed. A determination is made that an operand store compare hazard has been encountered. An entry within an operand store compare hazard prediction table is created based on the determination. The entry includes at least an instruction address of the instruction that has been executed and a hazard indicating flag associated with the instruction. The hazard indicating flag indicates that the instruction has encountered the operand store compare hazard. When a load instruction is associated with the hazard indicating flag the load instruction becomes dependent upon all store instructions associated with a substantially similar flag.
