Abstract: Various embodiments of systems and methods to allow and control simultaneous access and processing by multiple compute elements of multiple data sets stored in multiple memory modules. The compute elements request data to be processed without specifying any particular data sets to be received. Data interfaces receive the data requests from the compute elements, determine which data sets have not yet been served to the compute elements, select data sets to be served from among those that have not yet been served, and fetch these data sets from the memory modules. The process of requesting additional data by the compute elements, selection by the data interfaces of data sets to be served among those that have not yet been served, and providing such data sets by the data interfaces to the compute elements, may continue until all of the data sets have been served to the compute elements.
