We describe the process followed to integrate the IRJS screensaver with the IRJS grid computing middleware. Our goal is to provide a minimally invasive CPU scavenging technology. The IRJS screensaver launches a Compute Server (CS) when the computer enters a quiescent state. The CS joins the grid and volunteers its resources. The IRJS screensaver terminates the CS when any user input is detected. We use the [Saverbeans] framework to create our screensaver and to allow such behavior.
