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： 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 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.

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： Thread-data affinity optimization can be performed by a compiler during the compiling of a computer program to be executed on a cache coherent non-uniform memory access (cc-NUMA) platform. In one embodiment, the present invention includes receiving a program to be compiled. The received program is then compiled in a first pass and executed. During execution, the compiler collects profiling data using a profiling tool. Then, in a second pass, the compiler performs thread-data affinity optimization on the program using the collected profiling data.
