Abstract

Work division between the processor and accelerator is a common theme in modern heterogenous computing. Recent efforts (such as LEO and OpenAcc) provide directives that allow the developer to mark code regions in the original application from which offloadable tasks can be generated by the compiler. Auto-tuners and runtime schedulers work with the options (i.e., offloadable tasks) generated at compile time, which is limited by the directives specified by the developer. There is no provision for offload restructuring.

多核加速器可卸载任务的半自动重构
处理器和加速器之间的工作划分是现代异构计算的一个共同主题。最近的努力(如LEO和OpenAcc)提供了一些指令,允许开发人员在原始应用程序中标记代码区域,编译器可以从这些代码区域生成可卸载的任务。自动调优器和运行时调度器使用编译时生成的选项(即可卸载的任务),这受到开发人员指定的指令的限制。没有关于卸载重组的规定。
