Abstract: In this paper we present a CPUscavenging
architecture suitable for desktop resources,
and we study its appropriateness in exploiting the
PC Laboratory resources of the Greek School
Network and their integration to the existing
HellasGrid national infrastructure. School laboratories
form an extensive network equipped with
computational systems and fast Internet connections.
As this infrastructure is utilized at most 8 h per day and 5 days per week, it could be
made available during its remaining idle time for
computational purposes through the use of Grid
technology. The structure and organization of the
school laboratories and backbone network enables
the CPUscavenging service, as an independent
and additional service, which will not violate
the operational rules and policies of the school
network, while it will add additional resources
to the current HellasGrid infrastructure with low
adaptation cost.
