摘要： Basic blocks within a thread program are characterized for convergence based on variance analysis or corresponding instructions. Each basic block is marked as divergent based on transitive control dependence on a block that is either divergent or comprising a variant branch condition. Convergent basic blocks that are defined by invariant instructions are advantageously identified as candidates for scalarization by a thread program compiler.
摘要翻译：线程程序中的基本块的特点是基于方差分析或相应指令进行收敛。基于对发散或包含变异分支条件的块的传递控制依赖性，将每个基本块标记为发散。由不变指令定义的收敛基本块有利地被识别为线程程序编译器进行标量化的候选。

摘要： A technique is disclosed for executing a compiled parallel application on a general purpose processor. The compiled parallel application comprises parallel thread execution code, which includes single-instruction multiple-data (SIMD) constructs, as well as references to intrinsic functions conventionally available in a graphics processing unit. The parallel thread execution code is transformed into an intermediate representation, which includes vector instruction constructs. The SIMD constructs are mapped to vector instructions available within the intermediate representation. Intrinsic functions are mapped to corresponding emulated runtime implementations. The technique advantageously enables parallel applications compiled for execution on a graphics processing unit to be executed on a general purpose central processing unit configured to support vector instructions.
摘要翻译：公开了一种用于在通用处理器上执行编译并行应用的技术。编译并行应用程序包括并行线程执行代码，其包括单指令多数据（SIMD）结构，以及对图形处理单元中常规可用的内在函数的引用。并行线程执行代码被转换为包含向量指令结构的中间表示。 SIMD构造被映射到中间表示中可用的向量指令。内在函数映射到相应的仿真运行时实现。该技术有利地使编译为在图形处理单元上执行的并行应用能够在被配置为支持向量指令的通用中央处理单元上执行。

摘要： In one embodiment, the present invention includes a method for selecting a first transaction execution mode to begin a first transaction in a unbounded transactional memory (UTM) system having a plurality of transaction execution modes. These transaction execution modes include hardware modes to execute within a cache memory of a processor, a hardware assisted mode to execute using transactional hardware of the processor and a software buffer, and a software transactional memory (STM) mode to execute without the transactional hardware. The first transaction execution mode can be selected to be a highest performant of the hardware modes if no pending transaction is executing in the STM mode, otherwise a lower performant mode can be selected. Other embodiments are described and claimed.
摘要翻译：在一个实施例中，本发明包括一种用于在具有多个事务执行模式的无界事务存储器（UTM）系统中选择开始第一事务的第一事务执行模式的方法。这些事务执行模式包括在处理器的高速缓冲存储器内执行的硬件模式，使用处理器的事务硬件执行的硬件辅助模式以及软件缓冲器，以及在没有事务性硬件的情况下执行的软件事务存储器（STM）模式。如果在STM模式下没有执行等待事务，则可以将第一事务执行模式选择为硬件模式的最高执行模式，否则可以选择较低的执行模式。描述和要求保护其他实施例。

摘要： As described herein, an intermediate representation of a source code file may be used to explicitly express exception handling control flow prior to generating object code for the source code. As further described herein, a single uniform set of instructions of the intermediate representation may be used for expressing multiple different exception handling mechanisms related to multiple different programming languages. The intermediate form of the exception handling instructions may be generated by translating an intermediate language representation of the source code file. Representations of the source code in multiple different intermediate languages may be translated to a single uniform set of instructions of the intermediate representation. The intermediate form of the exception handling instructions may then be used by software development tools for such tasks as code generation, code optimization, code analysis etc. Thus, the same methods for code optimizations, analysis and generation may be used for intermediate representations of multiple different languages.

摘要： Methods and systems are described herein for extending configuration dependent extensible software programs. Classes of a core extensible software program may be extended by adding a configuration dependent extension. The extensions may be added statically prior to compiling the core version of a software program or dynamically at runtime. The declaration of extensible core classes may include an extensibility attribute with an indication of whether the class is statically extensible or dynamically extensible. An object description language is also described herein for appropriately declaring configuration dependent extensible classes. Also, a pre-processor is described herein for processing the object description language to generate a source code representation of the extensible class declarations and their extensions. The source code representation may then be used to generate the extended version of the core software program.
