HELP for parallel scientific programming

In the framework of data parallel programming, data mapping and physical mapping characterize existing languages. Our model HELP (Hyper-Espace et Langage Paralle`le) introduces the hyper-space notion. The programmer handles data parallel objects using two programming levels. At the macroscopic level, geometrical operators provide explicit communications and allow him to obtain data alignment in hyper-space. The microscopic level provides arithmetic treatments which are applied inside all hyper-space active points. Implicit communications are prohibited with the HELP model
