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.

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： Provided are a method, system, and program for parallelizing source code with a compiler. Source code including source code statements is received. The source code statements are processed to determine a dependency of the statements. Multiple groups of statements are determined from the determined dependency of the statements, wherein statements in one group are dependent on one another. At least one directive is inserted in the source code, wherein each directive is associated with one group of statements. Resulting threaded code is generated including the inserted at least one directive. The group of statements to which the directive in the resulting threaded code applies are processed as a separate task. Each group of statements designated by the directive to be processed as a separate task may be processed concurrently with respect to other groups of statements.

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.
