M.S. Paper Title: MEANTIME: Achieving Both Minimal Energy and
Timeliness with Approximate Computing

Abstract:
Energy efficiency and timeliness (i.e., predictable job latency) are
two essential – yet opposing – concerns for embedded systems. Hard
timing guarantees require conservative resource allocation while
energy minimization requires aggressively releasing resources and
occasionally violating timing constraints. Recent work on approximate
computing, however, opens up a new dimension of optimization:
application accuracy. In this paper, we use approximate computing to
achieve both hard timing guarantees and energy efficiency.
Specifically, we propose MEANTIME: a runtime system that delivers hard
latency guarantees and energy-minimal resource usage through small
accuracy reductions. We test MEANTIME on a real Linux/ARM system with
six applications. Overall, we find that MEANTIME never violates
real-time deadlines and sacrifices a small amount (typically less than
2%) of accuracy while reducing energy to 54% of a conservative, full
accuracy approach.

Anne's advisor is Prof. Henry Hoffmann
