摘要： Apparatus and methods for hardware assisted scheduling of software tasks in a computer system are disclosed. For example, a computer system comprises a first pool for maintaining a set of executable software threads, a first scheduler, a second pool for maintaining a set of active software threads, and a second scheduler. The first scheduler assigns a subset of the set of executable software threads to the set of active software threads and the second scheduler dispatches one or more threads from the set of active software threads to a set of hardware threads for execution. In one embodiment, the first scheduler is implemented as part of the operating system of the computer system, and the second scheduler is implemented in hardware.

摘要： A mechanism is provided for detecting false sharing misses. Responsive to performing either an eviction or an invalidation of a cache line in a cache memory of the data processing system, a determination is made as to whether there is an entry associated with the cache line in a false sharing detection table. Responsive to the entry associated with the cache line existing in the false sharing detection table, a determination is made as to whether an overlap field associated with the entry is set. Responsive to the overlap field failing to be set, identification is made that a false sharing coherence miss has occurred. A first signal is then sent to a performance monitoring unit indicating the false sharing coherence miss.
摘要翻译：提供了一种检测虚假共享漏洞的机制。响应于执行数据处理系统的高速缓冲存储器中的高速缓存行的驱逐或无效，在虚假共享检测表中确定是否存在与高速缓存行相关联的条目。响应于与虚假共享检测表中存在的高速缓存行相关联的条目，确定是否设置与条目相关联的重叠字段。响应于重叠字段未能设置，识别出发生错误共享一致性错误。然后，第一信号被发送到指示虚假共享一致性丢失的性能监视单元。

摘要： Techniques for replacing one or more blocks in a cache, the one or more blocks being associated with a plurality of data streams, are provided. The one or more blocks in the cache are grouped into one or more groups, each corresponding to one of the plurality of data streams. One or more incoming blocks are received. To free space, the one or more blocks of the one or more groups in the cache are invalidated in accordance with at least one of an inactivity of a given data stream corresponding to the one or more groups and a length of the one or more groups. The one or more incoming blocks are stored in the cache. A number of data streams maintained within the cache is maximized.

摘要： Techniques for encoded data processing which allow for continuous data processing as encoded data changes. Data is decomposed into one or more blocks with each block containing at least one data record. At least one data record within a given block is encoded with a first encoding process selected from one or more encoding processes. The first encoding process is associated with the given data block. Techniques evaluate whether or not to implement an encoding change for a given block when updating a given data record in the given block. Responsive to the evaluation, the given block is re-encoded with a second encoding process. Responsive to the re-encoding, the association of the given block is updated. A map is formed to convert the given data record encoded with the first encoding process to the second encoding process so as to preserve comparative relationships of the given data record.

摘要： An assignment constraint matrix is used in assigning work, such as data packets, from a plurality of sources, such as data queues in a network processing device, to a plurality of sinks, such as processor threads in the network processing device. The assignment constraint matrix is implemented as a plurality of qualifier matrixes adapted to operate simultaneously in parallel. Each of the plurality of qualifier matrixes is adapted to determine sources in a subset of supported sources that are qualified to provide work to a set of sinks based on assignment constraints. The determination of qualified sources may be based sink availability information that may be provided for a set of sinks on a single chip or distributed on multiple chips.

摘要： A program product and method of managing task execution on an integrated circuit chip such as a chip-level multiprocessor (CMP) with Simultaneous MultiThreading (SMT). Multiple chip operating units or cores have chip sensors (temperature sensors or counters) for monitoring temperature in units. Task execution is monitored for hot tasks and especially for hotspots. Task execution is balanced, thermally, to minimize hot spots. Thermal balancing may include Simultaneous MultiThreading (SMT) heat balancing, chip-level multiprocessors (CMP) heat balancing, deferring execution of identified hot tasks, migrating identified hot tasks from a current core to a colder core, User-specified Core-hopping, and SMT hardware threading.
