Abstract In this paper, we present a parallel programming and execution model based on alogicalordering of control flows. We show that it is possible to provide a unifying framework consisting of a synchronous programming model, thereby facilitating the mastery of programs, and an asynchronous execution model yielding efficient executions. Our approach is based on a SPMD and task parallel programming language, called SCL–Chan. Communications take place through channels and rely on explicit send/receive instructions. In contrast to classical message passing models, synchronizations and communications are dissociated. We show that it is possible to perform a data-driven automatic translation of sequential and arbitrary DOACROSS loops into SCL–Chan, by using nonmatching send/receive instructions. Our parallelization technique allows us to handle irregular control and leads to optimizations of communications in irregular computations.
