Abstract: A system to receive external data from one or more data sources, process the external data, determine available items of a first client, and retrieve user transactions associated with a targeted user. User attributes of the targeted user and item attributes of the available items are paired and the mean purchasing frequency for each of the pairs is determined. Global transactions of a population of users are analyzed to determine the standard deviation and a global mean purchasing frequency. A relevance score for each user attribute and item attribute pair is calculated. The item relevance score for each available item is determined based on the relevance score for each of the user attribute and item attribute pairs. Available items of the first client are selected based upon calculated relevance scores.

Abstract: Generally speaking, systems, methods and media for management of grid computing resources based on service level requirements are disclosed. Embodiments of a method for scheduling a task on a grid computing system may include updating a job model by determining currently requested tasks and projecting future task submissions and updating a resource model by determining currently available resources and projecting future resource availability. The method may also include updating a financial model based on the job model, resource model, and one or more service level requirements of an SLA associated with the task, where the financial model includes an indication of costs of a task based on the service level requirements. The method may also include scheduling performance of the task based on the updated financial model and determining whether the scheduled performance satisfies the service level requirements of the task and, if not, performing a remedial action.
