Abstract

Many advanced medical simulation applications are based on compute intensive numerical methods often exceeding the computational capacity available in hospitals and clinical centers. Addressing this issue, the EU Project GEMSS has developed a Grid infrastructure that supports the on-demand provision of medical simulation services running on remote parallel computers over the Internet. A flexible QoS infrastructure supporting dynamic negotiation of service level agreements and advance reservation of compute resources facilitates using Grid services for supporting time-critical clinical procedures. In this paper we present an overview of the GEMSS Grid infrastructure and outline the main issues involved in the provision of QoS-enabled Grid services and the negotiation of service level agreements for ensuring response time and price guarantees.
