“…Manual configuration of a pool's neighbors is required thus limiting the adaptivity of the system in case of dynamic changes in resource availability. It is also assumed that the pool managers run on reliable machines [15] since their failure can prevent the execution of new jobs. These problems can be approached with a Pastry [8] selforganizing overlay of condor pools [15].…”

These problems can be approached with a Pastry [8] selforganizing overlay of condor pools [15]. The condor pools are organized into a ring and proactively advertise their idle resources to their neighbors so that they can choose these advertised resources whenever necessary.…”

Resource requirements and availability in heterogeneous networks may frequently vary over their lifetime; thus producing equally variant overloaded and under-loaded situations. Typical architectures cannot cope with the frequent availability fluctuation of reusable, non-replicable and highly dynamic resources (such as network capacity). This paper proposes an unstructured P2P overlay for sharing resources between underutilized and overloaded networks. Its aim is to satisfy the excessive resource demands of some networks by using free resources from others given the high failure rate and unstable availability of these resources in wide networks. We describe and analyze the proposed Capacity Sharing Overlay Architecture and show, with extensive simulations, its ability to provide remote underutilized capacity to underlying networks, even in the presence of high node failure rates, helping the networks to handle more user queries.

“…O modelo apresentado em (Butt et al, 2003) utiliza o gerenciador de recursos do Condor para escalonar tarefas para os recursos ociosos, e somente irá invocar o mecanismo de agrupamento de Condors quando as máquinas estão ocupadas. Os resultados mostraram que esse tipo de agrupamento pode reduzir o tempo máximo de espera na fila.…”

“…It is reasonable to believe that wherever jobs execute at a given time, future jobs might soon be spawned at the same location. For example, newly submitted jobs are most likely to execute in the user's cluster unless a group of this user's jobs flock [ 9] to a distant cluster. Therefore, such jobs are serviced faster by readily available coins.…”

“…The number of Condor pools in EGEE alone is estimated in the hundreds. The various systems, despite belonging to the same grid organization, and despite potential collaboration (e.g., by means of flocking [ 9]), do not exchange and do not correlate user information. Furthermore, several state-of-the-art batch systems (e.g., Condor) do not have the necessary mechanisms to enforce an upper bound on the global utilization of the various resource types, even in the scope of a single pool.…”
