Performance evaluation of the Estimated Response Time strategy: tools, methods and an experiment

An extensive body of research focuses on economic and intelligent scheduling models. Conversely, the gLite matchmaking engine adopts an agnostic approach for estimating the waiting time of incoming jobs, derived from the Copernican principle: "this job is not special". An open question is the evaluation of this minimalist strategy. This work reports on the creation of the software tools required for this evaluation, the methodology and criteria, and presents preliminary results using the Grid Observatory logs of the Information System (IS) and PBS scheduler of GRIF/LAL.
