This study deals with mechanisms elaborated to map correctly Occam3 occam constructs in Ada95 Ada world. This differential study point out effects of those two approaches of parallelism. Trials and comparisons with others parallel systems will bring practical insight about procedures to make parallelism safe effective and usual.
