Abstract

In this paper, we propose and evaluate GrAMoS, a low-overhead WS-Agreement monitoring service that runs on Globus 4 and is integrated to JSS. To monitor resources and detect agreement violations, GrAMoS uses the stratified random sampling technique and proposes flexible agreement violation actions. The experimental results collected with a prototype of GrAMoS which monitored CPU reservation WS-Agreements show that the overhead incurred is lower than 2.8%, for grid tasks that take longer than 55s.
