摘要： Methods, systems, and computer program products are provided for scheduling threads in a multiprocessor computer. Embodiments include selecting a thread in a ready queue to be dispatched to a processor and determining whether an interrupt mask flag is set in a thread control block associated with the thread. If the interrupt mask flag is set in the thread control block associated with the thread, embodiments typically include selecting a processor, setting a current processor priority register of the selected processor to least favored, and dispatching the thread from the ready queue to the selected processor. In some embodiments, setting the current processor priority register of the selected processor to least favored is carried out by storing a value associated with the highest interrupt priority in the current processor priority register.

摘要： An apparatus and method for an improved bulk read socket call are provided. With the apparatus and method, a new field, so_rcvlen, is added to the socket structure that identifies the bulk read size requested by the user. The kernel of the prior art recv( ) function is also modified so that it sets the so_rcvlen to the size requested by the user prior to the recv( ) function going to sleep and waiting for the full data size requested by the user. A new flag, SP_MSGWAITALL, is also provided in the socket structure. In the TCP input processing, when data is received for a particular socket, the current setting of the SP_MSGWAITALL is checked. If the SP_MSGWAITALL flag is set, it is determined whether the amount of data stored in the socket receive buffer is less than the value of so_rcvlen. If not, the TCP input processing does not wake up the recv( ) thread. However, for every alternate segment, the TCP input processing sends back an acknowledgment (ACK). In the TCP output processing, when the SP_MSGWAITALL flag is set and the amount of data in the socket receive buffer is less than so_rcvlen, the full window is advertised. Once the TCP input processing determines that there is at least an amount of data in the socket receive buffer equal to the value of so_rcvlen, the TCP input processing will wake up the recv( ) thread and the SP_MSGWAITALL flag is reset.

摘要： The present invention provides a method that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. Specifically, a mechanism for providing and using a linear block address (LBA) translation protection table (TPT) to control out of user space I/O operations is provided. In one aspect of the present invention, the LBATPT includes an adapter protection table that has entries for each portion of a storage device. Entries include access control values which identify whether the entry is valid and what access type operations may be performed on a corresponding portion of a storage device. I/O requests may be checked against these access control values to determine if an application instance that submitted the I/O requests may access the LBAs identified in the I/O requests in the manner requested.

摘要： Input/output (I/O) requests generated by processes are typically stored in I/O queues. Because the queued I/O requests may not be associated with the processes that generated them, changing a process' priority may not affect the priority of the I/O requests generated by the process. Therefore, after the process' priority has been increased, it may be forced to wait for an I/O handler to service its I/O request, which may be stuck behind an I/O request generated by a lower priority process. Functionality can be implemented to associate the processes' priorities with the I/O requests generated by the processes. Also, reordering the queued I/O requests to reflect changes in the processes' priorities can ensure that the I/O requests from high priority processes are serviced before the I/O requests from low priority processes. This can ensure efficient processing and lower wait times for high priority processes.
摘要翻译：由进程生成的输入/输出（I / O）请求通常存储在I / O队列中。因为排队的I / O请求可能不与生成它们的进程相关联，所以更改进程的优先级可能不会影响进程生成的I / O请求的优先级。因此，在进程优先级增加之后，可能迫使其等待I / O处理程序来服务其I / O请求，这可能会被较低优先级进程生成的I / O请求所困扰。可以实现功能，将进程的优先级与进程生成的I / O请求相关联。此外，重新排序排队的I / O请求以反映进程优先级的更改可以确保在优先级较低的进程的I / O请求之前对来自高优先级进程的I / O请求进行服务。这可以确保高优先级进程的有效处理和较短的等待时间。

摘要： Automated techniques ensure that system central processing unit (“CPU”) power is not a bottleneck when migrating logical partitions from one system to another system or systems (e.g., in the event of a system evacuation). CPU resources needed to fully drive available bandwidth during the migration are computed. CPU resources of the system are then adjusted for the migration, which may comprise scaling down the CPU resources that are guaranteed for the executing partitions and/or adjusting relative partition variable weights to limit the amount of excess capacity that can be allocated to a partition.

摘要： A mechanism is provided that enables user space middleware or applications to pass file name based storage requests directly to a physical I/O Adapter without run-time involvement from the local Operating System (OS). A mechanism is provided for using a file protection table (FPT) data structure, which may include a file name protection table (FNPT) and file extension protection table (FEPT), to control user space and out of user space Input/Output (I/O) operations. In addition, a mechanism is provided for managing the FPT based on user space operations to create, query, modify and delete entries in the FPT.

摘要： The present invention provides a method that enables application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from either the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for determining whether a user space operation is a resource management operation of a work processing operation. If the user space operation is a resource management operation, appropriate functions are performed to either query, create, modify or destroy resource allocations in the I/O adapter. If the user space operation is a work processing operation, appropriate functions are performed to create work queue entries and inform the I/O adapter of the work queue entries and to retrieve completion queue entries for work queue entries whose processing has been completed by the I/O adapter.
