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： Data structure creation, organization and management techniques for data local to user-level threads are provided. In one embodiment, a method includes generating, for a user-level thread (“shred”) to run on a thread unit that is not managed by an operating system (“OS”), a storage area for local data and maintaining state in the storage area across a context switch from the thread unit that is not managed by the OS to a second thread unit that is managed by the OS. Other embodiments are also described and claimed.

摘要： Disclosed are embodiments of a system, methods and mechanism for management and translation of mapping between logical sequencer addresses and physical or logical sequencers in a multi-sequencer multithreading system. A mapping manager may manage assignment and mapping of logical sequencer addresses or pages to actual sequencers or frames of the system. Rationing logic associated with the mapping manager may take into account sequencer attributes when such mapping is performed Relocation logic associated with the mapping manager may manage spill and fill of context information to/from a backing store when re-mapping actual sequencers. Sequencers may be allocated singly, or may be allocated as part of partitioned blocks. The mapping manager may also include translation logic that provides an identifier for the mapped sequencer each time a logical sequencer address is used in a user program. Other embodiments are also described and claimed.

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.
