High-end systems and general-purpose computers alike are increasingly being configured with hardware accelerators. A typical system, or node of a large-scale platform, contains a few multicore processors that share memory, together with one or more coprocessors, such as a high-end accelerator board, an inexpensive programmable graphics card (GPGPU), or an FPGA (Field Programmable Gate Array). The coprocessors will typically have a different instruction set, distinct memory, a different operating environment and markedly different execution characteristics than the multicore component of the system. As a result, these heterogeneous platforms pose tough challenges with regard to their programmability. The goal of this research is to significantly simplify the process of developing code for heterogeneous platforms by providing a single, high-level programming interface that may be used across, and within, multicore processors and a broad variety of accelerators. Language features will be designed, in the form of an extension to the industry standard OpenMP API, that will enable the application developer to specify code regions for acceleration, along with the necessary synchronization and data motion. The implementation will translate the resulting enhanced OpenMP for a variety of heterogeneous platforms.

高端系统和通用计算机等越来越多地配置硬件加速器。典型的系统或大型平台的节点包含几个共享内存的多核处理器以及一个或多个协处理器，例如高端加速器板、廉价的可编程显卡 (GPGPU) 或 FPGA （现场可编程门阵列）。 协处理器通常具有与系统的多核组件不同的指令集、不同的存储器、不同的操作环境以及明显不同的执行特性。因此，这些异构平台对其可编程性提出了严峻的挑战。 这项研究的目标是通过提供可在多核处理器和各种加速器之间和内部使用的单一高级编程接口，显着简化为异构平台开发代码的过程。语言功能将以行业标准 OpenMP API 扩展的形式进行设计，使应用程序开发人员能够指定加速代码区域，以及必要的同步和数据移动。 该实施将把生成的增强型 OpenMP 转换为各种异构平台。
