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 resides in user space and may be part of a runtime library. The library may also include monitoring logic that monitors execution of a shredded program and provides scheduling hints, based on shred dependence information, to the scheduler. In addition, the scheduler may further optimize shred scheduling by taking into account information about a system's configuration of thread execution hardware. Other embodiments are also described and claimed.

摘要： A technique to monitor software thread performance and update software that issues or uses the thread(s) to reduce performance-inhibiting events. At least one embodiment of the invention uses hardware and/or software timers or counters to monitor various events associated with executing user-level threads and report these events back to a user-level software program, which can use the information to avoid or at least reduce performance-inhibiting events associated with the user-level threads.

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： 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： 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： 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.

The operating-system-scheduled thread and the persistent user-level thread may share a common virtual address space. Embodiments of the invention may also provide a method of causing a service thread running on an additional operating-system-visible sequencer to provide operating system services to the persistent user-level thread. Embodiments of the invention may further provide apparatus, system, and machine-readable medium thereof
