Abstract: What is disclosed is a set key and clear frame management function defined for a machine architecture of a computer system. In one embodiment, a machine instruction is obtained which identifies a first and second general register. Obtained from the first general register is a frame size field indicating whether a storage frame is one of a small block or a large block of data. Obtained from the second general register is an operand address of a storage frame upon which the instruction is to be performed. If the storage frame is a small block, the instruction is performed only on the small block. If the indicated storage frame is a large block of data, an operand address of an initial first block of data within the large block of data is obtained from the second general register. The frame management instruction is performed on all blocks starting from the initial first block.

Abstract: The conditions under which adapter interruptions are made pending are controlled. Responsive to an interruption being presented to an operating system, subsequent interruptions are suppressed on all central processing units in the configuration. The operating system processes the interruption, including examining and processing indicators of reported events until the operating system discontinues the suppression. This enables the operating system to control the number of pending interruptions and the number of processors processing those interruptions.

Abstract: One or more message signaled interruption requests from one or more input/output (I/O) adapters are converted to I/O adapter event notifications. Each I/O adapter event notification includes the setting of one or more specific indicators in system memory and an interruption request, the first of which results in a pending I/O adapter interruption request. While a request for an I/O adapter interruption is pending, subsequent message signaled interruption requests are converted to I/O adapter event notifications, but do not result in additional requests for I/O adapter interruptions.

Abstract: Un método de gestión de peticiones de interrupción en un entorno informático, caracterizado por comprender los pasos de: en respuesta a ejecutar una operación de interrupciones de registro de instrucción Modificar los Controles de Función de PCI (MPFC) que especifica un gestor de función de un adaptador, especificar (601) en una tabla localizada en un centro de entrada/salida (I/O) acoplado al adaptador, una ubicación en la memoria del sistema de un vector de bit de interrupción de adaptador (AIBV) del adaptador, el AIBV incluido en una formación de uno o más AIBV y una ubicación en la memoria del sistema de un bit de resumen de interrupción de adaptador (AISB) de una formación de AISB; recibir (603) desde el adaptador una petición de interrupción; y en respuesta a la petición recibida, fijar (605) por el centro de I/O un indicador en el AIBV que indica un tipo de evento desde el adaptador y fijar (606) el AISB que indica que un indicador está fijado en el AIBV.

Abstract: Automatically converting a synchronous data transfer to an asynchronous data transfer. Data to be transferred from a sender to a receiver is initiated using a synchronous data transfer protocol. Responsive to a determination that the data is to be sent asynchronously, the data transfer is automatically converted from the synchronous data transfer to the asynchronous data transfer.

Abstract: Un método para simplificar el procesado de E/S para una operación de E/S en un sistema de ordenador anfitrión configurado para comunicarse con una unidad de control, que comprende: obtener (1202) una palabra de orden de transporte para una operación de E/S que tiene datos tanto de entrada como de salida, especificando la palabra de orden de transporte una posición de los datos de salida y una posición para almacenar los datos de entrada; recopilar (1206) los datos de salida en respuesta a la posición de los datos de salida especificada por la palabra de orden de transporte; reenviar (1208) la operación de E/S y los datos de salida a la unidad de control para su ejecución; recibir (1210) los datos de entrada de la unidad de control; y almacenar (1212) los datos de entrada en la posición especificada por la palabra de orden de transporte para almacenar los datos de entrada.
