dc.description.abstract | This paper describes the support provided by the NanosCompiler to nested parallelism in OpenMP. The NanosCompiler is a source-to-source parallelizing compiler implemented around a hierarchical internal program representation that captures the parallelism expressed by the user (through OpenMP directives and extensions) and the parallelism automatically discovered by the compiler through a detailed analysis of data and control dependences. The compiler is finally responsible for encapsulating work into threads, establishing their execution precedences and selecting the mechanisms to execute them in parallel. The NanosCompiler enables the experimentation with different work allocation strategies for nested parallel constructs. Some OpenMP extensions are proposed to allow the specification of thread groups and precedence relations among them. |
