摘要： A method, system, and computer usable program product for a framework for scheduling tasks in a multi-core processor or multiprocessor system are provided in the illustrative embodiments. A thread is selected according to an order in a scheduling discipline, the thread being a thread of an application executing in the data processing system, the thread forming the leader thread in a bundle of threads. A value of a core attribute in a set of core attributes is determined according to a corresponding thread attribute in a set of thread attributes associated with the leader thread. A determination is made whether a second thread can be added to the bundle such that the bundle including the second thread will satisfy a policy. If the determining is affirmative, the second thread is added to the bundle. The bundle is scheduled for execution using a core of the multi-core processor.

摘要： A multiprocessor system includes a plurality of data processing nodes. Each node has a processor coupled to a system memory, a cache memory, and a cache directory. The cache directory contains cache coherency information for a predetermined range of system memory addresses. An interconnection enables the nodes to exchange messages. A node initiating a function shipping request identifies an intermediate destination directory based on a list of the function's operands and sends a message indicating the function and its corresponding operands to the identified destination directory. The destination cache directory determines a target node based, at least in part, on its cache coherency status information to reduce memory access latency by selecting a target node where all or some of the operands are valid in the local cache memory. The destination directory then ships the function to the target node over the interconnection.

摘要： A method for initializing variables within class objects in a statically loaded object-oriented programming language. A two-phase flooding algorithm is utilized to initialize the core variables within each class along with those variables needed to be initialized before the core variables. An initialization algorithm is performed within each of the class objects in a recursive manner. Once a class object has begun the initialization process internally, calls to again begin the initialization process within that class object from another class object will result in a return in order to prevent duplicates of the initialization process from being performed within each of the class objects.
摘要翻译：在静态加载的面向对象编程语言中初始化类对象中的变量的方法。利用两相淹没算法来初始化每个类中的核心变量以及在核心变量之前需要初始化的变量。以递归方式在每个类对象内执行初始化算法。一旦类对象已经在内部开始初始化过程，调用再次开始来自另一个类对象的类对象中的初始化过程将导致返回，以防止在每个类对象内执行初始化过程的重复。
