Abstract

The establishment of agreements between users and the entities which manage the Grid resources is still a challenging task. On the one hand, an entity in charge of dealing with the communication with the users is needed, with the aim of signing resource usage contracts and also implementing some renegotiation techniques, among others. On the other hand, some mechanisms should be implemented which decide if the QoS requested could be achieved and, in such case, ensuring that the QoS agreement is provided. One way of increasing the probability of achieving the agreed QoS is by performing meta-scheduling of jobs in advance, that is, jobs are scheduled some time before they are actually executed. In this way, it becomes more likely that the appropriate resources are available to run the jobs when needed. So, this paper presents a framework built on top of Globus and the GridWay meta-scheduler to provide QoS by means of performing meta-scheduling in advance. Thanks to this, QoS requirements of jobs are met (i.e. jobs are finished within a deadline). Apart from that, the mechanisms needed to manage the communication between the users and the system are presented and implemented through SLA contracts based on the WS-Agreement specification.
