  Process allocation for load distribution can improve system performance by utilizing resources efficiently. For primary-backup based fault tolerant system, a classic load-balancing process allocation method (two-stage allocation algorithm) has been proposed that can balance the load before as well as after faults occurrence. But two-stage allocation algorithm has bad scalability since its load-balancing performance reduces dramatically when each primary process is duplicated more than once (i.e., has more than one backup process). In this study, we present an improved algorithm named RSA (R-Stage Allocation algorithm) that can have the load better balanced no matter how many backup processes each primary process owns; Simulations are also used to compare the proposed algorithm with the two-stage allocation algorithm and the experimental results show that when extending to replicated R-Resilient processes, RSA has significantly better load distribution performance than two-stage allocation algorithm.
