Abstract :
CRAFT is a hybrid language that allows a user to program an MPP using many paradigms. The DOSHARED directive in CRAFT schedules the iterations of nested do-loops based upon the home of a specified array reference. It allows a user to have control over the location of the execution of the iterations of a loop. There are many complexities involved in the implementation of this directive; some of these complexities are discussed here
