摘要： Methods, systems, and mediums are described for scheduling data parallel tasks onto multiple thread execution units of processing system. Embodiments of a lock-free queue structure and methods of operation are described to implement a method for scheduling fine-grained data-parallel tasks for execution in a computing system. The work of one of a plurality of worker threads is wait-free with respect to the other worker threads. Each node of the queue holds a reference to a task that may be concurrently performed by multiple thread execution units, but each on a different subset of data. Various embodiments relate to software-based scheduling of data-parallel tasks on a multi-threaded computing platform that does not perform such scheduling in hardware. Other embodiments are also described and claimed.

摘要： A system and process for improving container flow within a port facility, including improved equipment and software for controlling operation and flow of the equipment in the part facility. The system may include a port facility geographically arranged to separate land operations and water operations. Land operations such as over-the-road missions and rail missions may use landside access areas positioned at one end of a yard including rows of container stacks. Water missions such as loading/discharging a vessel may use waterside access areas positioned at the opposite end of the yard. Automated cranes linked with a terminal operating system may pick/drop/shuffle containers and/or refrigerated containers (“reefers”) within the container stacks. Shuttle trucks may be used to pick/drop containers at quayside access points and the waterside access areas. The shuttle trucks may utilize shared wheelpaths. Software systems may be used to implement various principles of the invention.

摘要： An improved moving garbage collection algorithm is described. The algorithm allows efficient use of non-temporal stores to reduce the required time for garbage collection. Non-temporal stores (or copies) are a CPU feature that allows the copy of data objects within main memory with no interference or pollution of the cache memory. The live objects copied to new memory locations will not be accessed again in the near future and therefore need not be copied to cache. This avoids copy operations and avoids taxing the CPU with cache determinations. In a preferred embodiment, the algorithm of the present invention exploits the fact that live data objects will be stored to consecutive new memory locations in order to perform streaming copies. Since each copy procedure has an associated CPU overhead, the process of streaming the copies reduces the degradation of system performance and thus reduces the time for garbage collection.
摘要翻译：描述了改进的移动垃圾收集算法。该算法允许有效地使用非时间存储来减少垃圾收集所需的时间。非时间存储（或副本）是一种CPU功能，允许在主存储器内复制数据对象，而不会对高速缓冲存储器造成干扰或污染。复制到新内存位置的实时对象在不久的将来不再被访问，因此不需要复制到缓存中。这避免了复制操作，并避免了使用缓存确定对CPU进行征税。在优选实施例中，本发明的算法利用实时数据对象将被存储到连续的新存储器位置以便执行流拷贝的事实。由于每个复制过程都具有相关的CPU开销，所以流式传输副本的过程减少了系统性能的降级，从而减少了垃圾回收的时间。

摘要： Systems and methods may provide for identifying an object in a managed runtime environment and determining an age of the object at a software level of the managed runtime environment. Additionally, the object may be selectively allocated in one of a dynamic random access memory (DRAM) or a non-volatile random access memory (NVRAM) based at least in part on the age of the object. In one example, the data type of the object is also determined, wherein the object is selectively allocated further based on the data type.

摘要： Methods and apparatus to insert prefetch instructions based on garbage collector analysis and compiler analysis are disclosed. In an example method, one or more batches of samples associated with cache misses from a performance monitoring unit in a processor system are received. One or more samples from the one or more batches of samples based on delinquent information are selected. A performance impact indicator associated with the one or more samples is generated. Based on the performance indicator, at least one of a garbage collector analysis and a compiler analysis is initiated to identify one or more delinquent paths. Based on the at least one of the garbage collector analysis and the compiler analysis, one or more prefetch points to insert prefetch instructions are identified.
