Consider the task dependency graphs of the two database query decompositions:

Consider the task dependency graphs of the two database query decompositions: What are the critical path lengths for the two task dependency graphs? If each task takes 10 time units, what is the shortest parallel execution time for each decomposition? How many processors are needed in each case to achieve this minimum parallel execution time? What is the maximum degree of concurrency
