This article describes a technique for path unfolding for conditional branches in parallel programs executed on clusters. Unfolding paths following control structures makes it possible to break the control dependencies existing in the code and consequently to obtain a high degree of parallelism through the use of idle CPUs. The main challenge of this technique is to deal with sequences of control statements. When a control statement appears in a path after a branch, a new conditional block… CONTINUE READING
