摘要： A mechanism is provided for determining whether to use cache affinity as a criterion for software thread dispatching in a shared processor logical partitioning data processing system. The server firmware may store data about when and/or how often logical processors are dispatched. Given these data, the operating system may collect metrics. Using the logical processor metrics, the operating system may determine whether cache affinity is likely to provide a significant performance benefit relative to the cost of dispatching a particular logical processor to the operating system.

摘要： A mechanism is provided for biasing placement of a software thread on a currently idle and dispatched processor. The operating system starts with the last logical processor on which the software thread ran and determines whether that processor is idle and dispatched and considers each logical processor until a currently dispatched and idle logical processor is found. If a currently dispatched and idle logical processor is not found, then the operating system biases placing the software thread on an idle logical processor.

摘要： Terminating an accelerator application program in a hybrid computing environment that includes a host computer having a host computer architecture and an accelerator having an accelerator architecture, where the host computer and the accelerator are adapted to one another for data communications by a system level message passing module (‘SLMPM’), and terminating an accelerator application program in a hybrid computing environment includes receiving, by the SLMPM from a host application executing on the host computer, a request to terminate an accelerator application program executing on the accelerator; terminating, by the SLMPM, execution of the accelerator application program; returning, by the SLMPM to the host application, a signal indicating that execution of the accelerator application program was terminated; and performing, by the SLMPM, a cleanup of the execution environment associated with the terminated accelerator application program.

摘要： A method, system and program are provided for dynamically allocating DMA channel identifiers to multiple DMA transfer requests that are grouped in time by virtualizing DMA transfer requests into an available DMA channel identifier using a channel bitmap listing of available DMA channels to select and set an allocated DMA channel identifier. Once the input values associated with the DMA transfer requests are mapped to the selected DMA channel identifier, the DMA transfers are performed using the selected DMA channel identifier, which is then deallocated in the channel bitmap upon completion of the DMA transfers. When there is a request to wait for completion of the data transfers, the same input values are used with the mapping to wait on the appropriate logical channel. With this method, all available logical channels can be utilized with reduced instances of false-sharing.
摘要翻译： 提供了一种方法，系统和程序，用于通过使用可用DMA通道的频道位图列表将DMA传送请求虚拟化为可用的DMA通道标识符来动态地将DMA通道标识符分配给多个DMA传送请求，这些DMA传送请求按时间分组，以选择和设置分配的 DMA通道标识符。 一旦与DMA传输请求相关联的输入值被映射到所选择的DMA通道标识符，则使用所选择的DMA通道标识符来执行DMA传输，然后DMA通道标识符在完成DMA传输后被释放在通道位图中。 当有要求等待数据传输完成时，使用与映射相同的输入值来等待适当的逻辑信道。 利用这种方法，可以利用所有可用的逻辑信道来减少假共享的实例。
