Almost all coarse grained program graph nodes don't need all of their input operands at the beginning of their execution. Thereafter they can be scheduled a bit earlier. This type of program graph nodes triggering is called partial strict triggering. The missing operands will be requested later during the execution. Coarse grained program graph nodes send their output operand to all successors, as soon as they produce them. Successors of coarse grained program graph nodes will be scheduled earlier too, because they will receive their input operands sooner. An evaluation of improved CPM, VL and DSH scheduling algorithms is done in this paper. We have improved them with partial strict triggering of coarse grained program graph nodes
