摘要： A method and system that prepares a task for being swapped out from processor utilization that is executing on a computer with multiple processors that each support multiple streams. The task has one or more teams of threads, where each team represents threads executing on a single processor. The task designates, for each stream that is executing a thread, one stream as a team master stream and one stream as a task master stream. For each team master stream, the task notifies the operating system that the team is ready to be swapped out when each other thread of the team has saved its state and has quit its stream. Finally, for the task master stream, the task notifies the operating system that the task is ready to be swapped when it has saved its state and each other team has notified that it is ready to be swapped out.

摘要： Various techniques for manipulating data using access states of memory, access control fields of pointers and operations, and exception raising and exception trapping in a multithreaded computer system. In particular, the techniques include synchronization support for a thread blocked in a word, demand evaluation of values, parallel access of multiple threads to a list, synchronized and unsynchronized access to a data buffer, use of forwarding to avoid checking for an end of a buffer, use of sentinel word to detect access past a data structure, concurrent access to a word of memory using different synchronization access modes, and use of trapping to detect access to restricted memory.
摘要翻译： 使用存储器访问状态，指针和操作的访问控制字段以及多线程计算机系统中异常引发和异常捕获来处理数据的各种技术。 特别地，这些技术包括对一个字中被阻塞的线程的同步支持，对值的需求评估，多个线程到列表的并行访问，对数据缓冲器的同步和非同步访问，使用转发以避免检查 缓冲区，使用前哨字来检测通过数据结构的访问，使用不同的同步访问模式并发访问一个单词的内存，并使用陷阱来检测对受限内存的访问。
