14 copies of a code module are to be executed in parallel on identical processors organized into two communicating clusters, A and B. Cluster A contains 16 processors and cluster B contains 32 processors. Code modules run on one processor at a time. a. How many different sets of processors can be used if cluster A has 3 failed processors and cluster B has 2 failed processors? b. How many different sets of processors can be used if all modules are to be executed either on cluster A or on cluster B? (This question is separate from a.).
