In this demo we present our approach to interoperate a service grid (SG) based on the gLite middleware with an opportunistic grid (OG) based on the OurGrid middleware. In addition to the traditional gateway-based approach, we have also leveraged on the facilities of OurGrid to provide a way to opportunistically explore the SG resources whenever they are idle. The advantages of this approach are threefold: firstly, it allows idle resources belonging to the SG to be used in an opportunistic way, improving the efficiency of the service grid; secondly, the provision of an OG allows shared resources to be added to the infrastructure, a feature that turns out to be very important for consortia in which many of the member institutions cannot afford the provision of dedicated resources; finally, the OG can efficiently execute the embarrassingly parallel workload, liberating the SG to execute mostly tightly-coupled applications, with a great reduction on the response time of these applications.
