A method for execution by a request scheduler includes receiving a set of requests for execution from at least one request issuer. Resource requirements are determined for each of the set of requests, and current resource availability data is determined for resources indicated in the resource requirements. Scheduling data is generated for the set of requests based on the resource requirements and the current resource availability data. A first subset of the set of requests are added to a queue in response to the scheduling data indicating the first subset of the set of requests be queued for execution. Execution of the set of requests is facilitated in accordance with the scheduling data by facilitating immediate, simultaneous execution of a second subset of the set of requests and by facilitating serial execution of the first subset of the set of requests.
