摘要： The present invention provides a computer implemented method and apparatus to assign software threads to a common virtual processor of a data processing system having multiple virtual processors. A data processing system detects cooperation between a first thread and a second thread with respect to a lock associated with a resource of the data processing system. Responsive to detecting cooperation, the data processing system assigns the first thread to the common virtual processor. The data processing system moves the second thread to the common virtual processor, whereby a sleep time associated with the lock experienced by the first thread and the second thread is reduced below a sleep time experienced prior to the detecting cooperation step.

摘要： The present invention thus provides for a method, system, and computer-usable medium that afford an equitably charging of a customer for computer usage time. In a preferred embodiment, the method includes the steps of: tracking an amount of computer resources in a Simultaneous Multithreading (SMT) computer that are available to a customer for a specified period of time; determining if the computer resources in the SMT computer are operating at a nominal rate; and in response to determining that the computer resources are operating at a non-nominal rate, adjusting a billing charge to the customer, wherein the billing charge reflects that the customer has available computer resources, in the SMT computer, that are not operating at the nominal rate during the specified period of time.

摘要： A method for serializing access to computer system resources without disabling interrupts in critical code sections or requiring excessive use of spin locks. A queue lock is introduced that allows an interrupt process to enqueue and be processed in turn without a spin lock and to block process code access to a particular resource until all interrupts are processed. Process level code is blocked from accessing a locked resource while requests for accesses from interrupt level code are queued in a deferred work queue which is processed prior to the release of the blocking lock. Establishment of deferred work queue means that processing can continue without disablement of interrupts and without significant overhead consumed by processes holding spin locks.

摘要： A method for memory management and block paging in a control program that controls the execution of tasks on behalf of a plurality of system computing entities, which selects, transfers blocks of data, such as pages, between storage and memory to maintain in memory only those blocks of data necessary for current system processing requirements. Pages in memory are first identified as not referenced within a preceding time period, for example, since the last examination by a core table scan mechanism, on a system wide basis. Pages so identified are then grouped into blocks of pages used by a computing entity and then transferred to storage for later retrieval as a set when any one of the pages in the set is required by the system. Pages not referenced while resident are made available for paging to memory individually. Block paging achieves a significant reduction in the system overhead associated with memory management, as compared with prior art paging mechanisms. Demand driven systemwide or global least recently used memory management achieves more efficient memory utilization.
摘要翻译：一种用于控制程序中的存储器管理和块寻呼的方法，其控制代表多个系统计算实体的任务执行，所述多个系统计算实体选择在存储器和存储器之间传送诸如页之类的数据块，以仅在存储器中维持那些当前系统处理要求所需的数据块。首先，在系统范围的基础上，在前一时间段内首先将内存中的页面识别为未被引用，例如，由核心表扫描机构进行的最后检查。然后将如此识别的页面分组为计算实体使用的页面块，然后在系统中需要该集合中的任何一个页面时，将其转移到存储以供稍后检索。驻留时使用的页面不可用于分页分页。与现有技术的寻呼机制相比，块寻呼实现了与存储器管理相关联的系统开销的显着降低。需求驱动的全系统或全球最近使用的内存管理实现了更高效的内存利用率。
