This paper presents ALTER, an adaptive failure detection service, which incorporates the technique of unreliable failure detection service and the idea of R-GMA. ALTER is organized in a hierarchical structure and it can be adaptive to the system conditions and user requirements with changing the system parameters and system organizations. With mathematical evaluation, ALTER shows good scalab.lity and flexibility, which is suitable for grid environments. Copyright 2006 ACM.
