Many applications foreseen for exascale era should process huge amount of data. However, the IO infrastructure of current supercomputing architecture cannot be generalized to deal with this amount of data due to the need for excessive data movement from storage layers to compute nodes leading to limited scalability. There has been extensive studies addressing this challenge. Decoupled Execution Paradigm (DEP) is an attractive solution due to its unique features such as available fast storage devices close to computational units and available programmable units close to file system.
