Abstract

Data-parallel languages offer a programming model structured and easy to understand. The challenge consists in taking advantage of the power of present parallel architectures by a compilation process allowing to reduce the number and the complexity of synchronizations. In this paper, we clearly separate the synchronous programming model from the asynchronous execution model by the way of a translation from a synchronous data-parallel programming language into an asynchronous target language. The synchronous data-parallel programming language allows to temporarily mask local computations. The asynchronous target language handles explicit and partial synchronizations through the use of structural clocks.
