摘要： An abstraction layer is comprised in the operating system that represents the particulars of the PPMs. The abstractions in the abstraction layer are differentiated from one another by parameters representing the characteristics of the PPMs. The dispatcher uses the abstraction to balance processing loads when assigning execution threads to the PPMs. The assigning of the execution threads and the balancing of the processing loads is performed while taking account of the characteristics of the PPMs, such as shared resources and clock speed.

摘要： In general, the invention relates to a system that includes a multi-core processor and a dispatcher operatively connected to the multi-core processor. The dispatcher is configured to receive a first plurality of threads during a first period of time, dispatch the first plurality of threads only to a first core of the plurality of cores, receive a second plurality of threads during a second period of time, dispatch the second plurality of threads only to a second core of the plurality of cores, migrate to the second core any of the first plurality of threads that are still executing on the first after the first period of time has elapsed. The duration of the first period of time and the duration of the second period of time are determined using a thread migration schedule, and thread migration schedule is determined using at least one thermal characteristic of the multi-core processor.

摘要： A device, system, and method are directed towards managing power consumption in a computer system with one or more processing units, each processing unit executing one or more threads. Threads are characterized based on a cycles per instruction (CPI) characteristic of the thread. A clock frequency of each processing unit may be configured based on the CPI of each thread assigned to the processing unit. In a system wherein higher clock frequencies consume greater amounts of power, the CPI may be used to determine a desirable clock frequency. The CPI of each thread may also be used to assign threads to each processing unit, so that threads having similar characteristics are grouped together. Techniques for assigning threads and configuring processor frequency may be combined to affect performance and power consumption. Various specifications or factors may also be considered when scheduling threads or determining processor frequencies.

摘要： Methods and apparatus, including computer program products, implementing and using techniques for alerting one or more computer software application threads waiting to retrieve events from an event port. An alert event generated by a computer software application is received at the event port. A state of the event port is changed to an alert state, if the event port is not already in an alert state, in response to receiving the alert event. One or more of the computer software application threads is notified about the alert state of the event port.

摘要： In a multiprocessing computer system, a schedulable process entity (such as a UNIX process, a Solaris lightweight process, or a Windows NT thread) sets a memory flag (sc.sub.-- nopreempt) before acquiring a shared resource. This flag tells the operating system that the process entity should not be preempted. When it is time for the process entity to be preempted, but sc.sub.-- nopreempt is set, the operating system sets a flag (sc.sub.-- yield) to tell the process entity that the entity should surrender the CPU when the entity releases the shared resource. However, the entity is not preempted but continues to run. When the entity releases the shared resource, the entity checks the sc.sub.-- yield flag. If the flag is set, the entity makes an OS call to surrender the CPU.
摘要翻译：在多处理计算机系统中，可调度的进程实体（例如UNIX进程，Solaris轻量进程或Windows NT线程）在获取共享资源之前设置内存标志（sc-nopreempt）。该标志告诉操作系统，流程实体不应被抢占。当流程实体被抢占时，但设置sc-nopreempt时，操作系统设置一个标志（sc-yield）来告知进程实体实体释放共享资源时该实体应该放弃CPU。但是，该实体不被抢占，而是继续运行。当实体释放共享资源时，实体检查sc-yield标志。如果标志被设置，则实体进行OS调用以投降CPU。

摘要： In a computer system, a descriptive memory allocation system is described having a memory policy allocation module for setting memory allocation policies by an operating system in response to descriptive resource use requirements provided by an application requesting access to a specified address range in memory. The descriptive memory allocation system includes a descriptive resource allocator that uses descriptive memory use advice provided by an application to decide how to allocate memory to the application. The descriptive resource allocator includes memory allocation policies that may be set by the operating system after the operating system has determined the appropriate allocation scheme to implement based on an allocation advice provided by a requesting after the application. The application in providing its descriptive memory use information does not specify a specific allocation policy the operating system should use to allocate memory to it.

摘要： Method for enabling the dynamic modification of cluster configurations, and apparatus including software to perform the method. To enable this dynamic modification, cluster configuration data is stored as a table in a cluster configuration repository that is accessible from all nodes in the cluster. Accordingly, the present invention enables the modification of the cluster configuration from any node in the cluster dynamically. When a reconfiguration command is given, the configuration table is changed and all the nodes in the cluster are notified of the changed configuration in parallel. Following the notification by the nodes of the changed cluster configuration, the changes to the cluster are implemented dynamically as specified by the command.
