Abstract:
Virtual screening has proven a very effective method on grid infrastructures. Operating a dedicated virtual screening platform on grid resources requires optimizing the scheduling policy. The scheduling can be done at 2 levels; at site level and at platform level. Site scheduling is done at each site independently. Each site allocates time slots for different groups of users. Platform scheduling is done at group level: inside a time slot jobs from many users are allocated. Pilot agents are sent to sites and act as a container of actual users jobs. They pick up users jobs from a central queue where the platform scheduling is done. This paper focus on finding platform scheduling policy for pilot-agent platform shared by many virtual screening users. They need a suitable scheduling algorithm at platform level to ensure a certain fairness between users.
