Consider the following concurrent program:CPU 1if B thencobeginCPU 2; I/O2coendelseI/O1end.Derive expressions for the completion time distribution and the mean completiontime for the whole graph. Assume that the execution time of the statement groupCPUi (i = 1, 2) is EXP(i), the execution time of the statement group I/Oj(j = 1, 2) is EXP(j ), and P(B = true) = p. Assume all task executing times aremutually independent. For enhancing such models to allow for task failures, seeSahner et al. [SAHN 1996].
