%X Reliability optimization for computer networks, subjects to cost constraints, is a NP\|hard combinational problem. Regarding a known network topology, the problem of choosing links and switchers among alternatives different in reliability and cost is settled by a Coarse\|grained parallel genetic algorithm, which maximize the network availablity within a fixed budget. The simulations on a dedicated cluster demonstrate that contracting to the sequential counterpart, our parallel GA improves the quality of plans greatly with an evident speed\|up.
