When Data Management Systems Meet Approximate Hardware: Challenges and Opportunities

Recently, approximate hardware designs have got many research interests in the computer architecture community. The essential idea of approximate hardware is that the hardware components such as CPU, memory and storage can trade off the accuracy of results for increased performance, reduced energy consumption, or both. The authors propose a DBMS ApproxiDB with its design, implementation and optimization aware of the underlying approximate hardware. ApproxiDB will run on a hybrid machine consisting of both approximate hardware and precise hardware (i.e., the conventional hardware without sacrificing the accuracy).
