Abstract :
This paper presents CRAC, an environment dedicated to design efficient asynchronous iterative algorithms for a grid architecture. Those algorithms are particularly suited for grid architecture since they naturally allow to overlap communications by computations. Each processor computes its iterations freely without any synchronization with its neighbors. All the characteristics of CRAC are described. A real application using four distant clusters, with a total of 120 processors, shows the interest of this environment and of asynchronous algorithms.
