Abstract
This paper proposes a scheme for the automatic detection of parallelism among coarse grain tasks (macrotasks) in a Fortran program. In this scheme parallelism is represented as the EXECUTION START CONDITION for each macrotask in a program. This condition is represented by a logical expression that states when, in relation to other macrotasks, the execution of a certain macrotask can be started. This representation aids in scheduling a set of macrotasks onto processors. To construct such an expression, a novel concept called co-control dependence is introduced. Analyzing co-control dependence together with control dependence and data dependences among macrotasks, the scheme detects and describes successfully the parallelism among all macrotasks in a program.
