摘要： A compile environment is provided in a computer system that allows programmers to program both CPUs and data parallel devices (e.g., GPUs) using a high level general purpose programming language that has data parallel (DP) extensions. A compilation process translates modular DP code written in the general purpose language into DP device source code in a high level DP device programming language using a set of binding descriptors for the DP device source code. A binder generates a single, self-contained DP device source code unit from the set of binding descriptors. A DP device compiler generates a DP device executable for execution on one or more data parallel devices from the DP device source code unit.

摘要： A software transactional memory (STM) system allows the composition of traditional lock based synchronization with transactions in STM code. The STM system acquires each traditional lock the first time that a corresponding traditional lock acquire is encountered inside a transaction and defers all traditional lock releases until a top level transaction in a transaction nest commits or aborts. The STM system maintains state information associated with traditional lock operations in transactions and uses the state information to eliminate deferred traditional lock operations that are redundant. The STM system integrates with systems that implement garbage collection.

摘要： A software transactional memory system implements a lightweight key-based action framework. The framework includes a set of unified application programming interfaces (APIs) exposed by an STM library that allow clients to implement actions that can be registered, queried, and updated using specific keys by transactions or transaction nests in STM code. Each action includes a key, state information, and a set of one or more callbacks that can be hooked to the validation, commit, abort, and/or re-execution phases of transaction execution. The actions extend the built-in concurrency controls of the STM system with customized control logics, support transaction nesting semantics, and enable integration with garbage collection systems.
