摘要： A method and apparatus are provided for efficiently managing hot spots in a resource managed computer system. The system utilizes a controller, a series of requestor groups, and a series of loan registers. The controller is configured to allocate and is configured to reallocate resources among the requestor groups to efficiently manage the computer system. The loan registers account for reallocated resources such that intended preallocation of use of shared resources is closely maintained. Hence, the computer system is able to operate efficiently while preventing any single requestor or group of requestors from monopolizing shared resources.

摘要： A method, system and computer-usable medium are disclosed for managing transient instruction streams. Transient flags are defined in Branch-and-Link (BRL) instructions that are known to be infrequently executed. A bit is likewise set in a Special Purpose Register (SPR) of the hardware (e.g., a core) that is executing an instruction request thread. Subsequent fetches or prefetches in the request thread are treated as transient and are not written to lower-level caches. If an instruction is non-transient, and if a lower-level cache is non-inclusive of the L1 instruction cache, a fetch or prefetch miss that is obtained from memory may be written in both the L1 and the lower-level cache. If it is not inclusive, a cast-out from the L1 instruction cache may be written in the lower-level cache.
摘要翻译：公开了用于管理瞬时指令流的方法，系统和计算机可用介质。在已知很少执行的分支和链路（BRL）指令中定义了瞬态标志。在执行指令请求线程的硬件（例如，核心）的专用寄存器（SPR）中同样设置一个位。请求线程中的后续提取或预取将被视为暂时的，并且不会写入低级缓存。如果指令是非瞬态的，并且如果低级缓存不包括L1指令高速缓存，则从存储器获得的获取或预取缺失可以被写入L1和下级高速缓存中。如果不包括在内，则可以将低速缓存中的L1指令高速缓存中的退出写入。

摘要： A method, system and computer-usable medium are disclosed for managing prefetch streams in a virtual machine environment. Compiled application code in a first core, which comprises a Special Purpose Register (SPR) and a plurality of first prefetch engines, initiates a prefetch stream request. If the prefetch stream request cannot be initiated due to unavailability of a first prefetch engine, then an indicator bit indicating a Prefetch Stream Dispatch Fault is set in the SPR, causing a Hypervisor to interrupt the execution of the prefetch stream request. The Hypervisor then calls its associated operating system (OS), which determines prefetch engine availability for a second core comprising a plurality of second prefetch engines. If a second prefetch engine is available, then the OS migrates the prefetch stream request from the first core to the second core, where it is initiated on an available second prefetch engine.

摘要： An approach is provided to identify a disabled processing core and an active processing core from a set of processing cores included in a processing node. Each of the processing cores is assigned a cache memory. The approach extends a memory map of the cache memory assigned to the active processing core to include the cache memory assigned to the disabled processing core. A first amount of data that is used by a first process is stored by the active processing core to the cache memory assigned to the active processing core. A second amount of data is stored by the active processing core to the cache memory assigned to the inactive processing core using the extended memory map.

摘要： A computer-implemented method, data processing system, and computer usable program code are provided for reducing memory access latency. A memory controller receives a memory access request and determines if an address associated with the memory access request falls within an address range of a plurality of paired memory address range registers. The memory controller determines if an enable bit associated with the address range is set to 1 in response to the address falling within one of the address ranges. The memory controller flags the memory access request as a high-priority request in response to the enable bit being set to 1 and places the high-priority request on a request queue.A dispatcher receives an indication that a memory bank is idle. The dispatcher determines if high-priority requests are present in the request queue and, if so, sends the earliest high-priority request to the idle memory bank.
