摘要： Methods, data structures, instructions, and techniques for structured exception handling for user-level threads in a multi-threading system are provided. Registered filter routines may be dispatched to a thread unit not managed by the operating system (OS). The dispatch may occur by allowing an OS-managed thread unit (proxy) to invoke the OS-provided structured exception handling service (including dispatcher) on behalf of the sequestered thread unit. Alternatively, an OS-managed thread unit may include dispatch code and may, without OS intervention, dispatch the filter routine to the sequestered thread unit. Other embodiments are also described and claimed.

摘要： Embodiments described herein disclose a system for enabling emulation of a MIMD ISA extension which supports user-level sequencer management and control, and a set of privileged code executed by both operating system managed sequencers and application managed sequencers, including different sets of persistent per-CPU and per-thread data. In one embodiment, a lightweight code layer executes beneath the operating system. This code layer is invoked in response to particular monitored events, such as the need for communication between an operating system managed sequencer and an application managed sequencer. Control is transferred to this code layer, for execution of special operations, after which control returns back to originally executing code. The code layer is normally dormant and can be invoked at any time when either a user application or the operating system is executing.

摘要： In an embodiment, a method is provided. The method includes managing user-level threads on a first instruction sequencer in response to executing user-level instructions on a second instruction sequencer that is under control of an application level program. A first user-level thread is run on the second instruction sequencer and contains one or more user level instructions. A first user level instruction has at least 1) a field that makes reference to one or more instruction sequencers or 2) implicitly references with a pointer to code that specifically addresses one or more instruction sequencers when the code is executed.

摘要： Method, apparatus and system embodiments to schedule OS-independent “shreds” without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. A scheduler routine may run on each enabled sequencer. The schedulers may retrieve shred descriptors from a queue system. The sequencer associated with the scheduler may then execute the shred described by the descriptor. Other embodiments are also described and claimed.

摘要： Operating system services are transparently triggered for thread execution resources (“sequencers”) that are sequestered from view of the operating system. A “surrogate” thread that is managed by, and visible to, the operating system is utilized to acquire OS services on behalf of a sequestered sequencer. Multi-shred contention for shred-specific resources may thus be alleviated. Other embodiments are also described and claimed.

摘要翻译： 对于从操作系统视图隔离的线程执行资源（“sequencer”），操作系统服务被透明地触发。 由操作系统管理并且对操作系统可见的“代理”线程用于代表隔离定序器获取OS服务。 因此可以减轻碎片专用资源的多重争用争用。 还描述和要求保护其他实施例。

摘要： Method, apparatus and system embodiments to schedule user-level OS-independent “shreds” without intervention of an operating system. For at least one embodiment, the shred is scheduled for execution by a scheduler routine rather than the operating system. The scheduler routine may receive compiler-generated hints from a compiler. The compiler hints may be generated by the compiler without user-provided pragmas, and may be passed to the scheduler routine via an API-like interface. The interface may include a scheduling hint data structure that is maintained by the compiler. Other embodiments are also described and claimed.
