    Abstract: 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.

    Abstract: Functionality is implemented to determine that a plurality of multi-core processing units of a system are configured in accordance with a plurality of operating performance modes. It is determined that a first of the plurality of operating performance modes satisfies a first performance criterion that corresponds to a first workload of a first logical partition of the system. Accordingly, the first logical partition is associated with a first set of the plurality of multi-core processing units that are configured in accordance with the first operating performance mode. It is determined that a second of the plurality of operating performance modes satisfies a second performance criterion that corresponds to a second workload of a second logical partition of the system. Accordingly, the second logical partition is associated with a second set of the plurality of multi-core processing units that are configured in accordance with the second operating performance mode.

    Abstract: 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 requester 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 requesters from monopolizing shared resources.

    Abstract: An approach is provided to identifying cache extension sizes that correspond to different partitions that are running on a computer system. The approach extends a first hardware cache associated with a first processing core that is included in the processor's silicon substrate with a first memory allocation from a system memory area, with the system memory area being external to the silicon substrate and the first memory allocation corresponding to one of the plurality of cache extension sizes that corresponds to one of the partitions that is running on the computer system. The approach further extends a second hardware cache associated with a second processing core also included in the processor's silicon substrate with a second memory allocation from the system memory area with the second memory allocation corresponding to another of the cache extension sizes that corresponds to a different partitions that is being executed by the second processing core.

    Abstract: 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.
