Abstract
In the early stage of processor design, Dynamic Thermal Management (DTM)
schemes should be evaluated to avoid excessively high temperature,
while minimizing performance overhead as small as possible. In this
paper, we show that conventional thermal simulations using fixed ambient
temperature may lead to wrong conclusion in terms of performance and
temperature; though ambient temperature converges to a steady state
after hundreds of seconds, the steady state ambient temperature is
significantly different depending on applications. To overcome the
inaccuracy of conventional thermal simulations, we propose that
architectural thermal simulation should exploit application-dependent
ambient temperature. Our evaluation results show that the performance of
the same DTM scheme is different, when application-dependent ambient
temperature (compared to fixed temperature) is used. For accurate
simulation, future architectural thermal researchers are expected to
evaluate their proposed DTM schemes, reflecting application- dependent
ambient temperature.
