Query: Efficient Uncertainty Modeling for System Design via Mixed Integer
  Programming   The post-Moore era casts a shadow of uncertainty on many aspects of computer
system design. Managing that uncertainty requires new algorithmic tools to make
quantitative assessments. While prior uncertainty quantification methods, such
as generalized polynomial chaos (gPC), show how to work precisely under the
uncertainty inherent to physical devices, these approaches focus solely on
variables from a continuous domain. However, as one moves up the system stack
to the architecture level many parameters are constrained to a discrete
(integer) domain. This paper proposes an efficient and accurate uncertainty
modeling technique, named mixed generalized polynomial chaos (M-gPC), for
architectural uncertainty analysis. The M-gPC technique extends the generalized
polynomial chaos (gPC) theory originally developed in the uncertainty
quantification community, such that it can efficiently handle the mixed-type
(i.e., both continuous and discrete) uncertainties in computer architecture
design. Specifically, we employ some stochastic basis functions to capture the
architecture-level impact caused by uncertain parameters in a simulator. We
also develop a novel mixed-integer programming method to select a small number
of uncertain parameter samples for detailed simulations. With a few highly
informative simulation samples, an accurate surrogate model is constructed in
place of cycle-level simulators for various architectural uncertainty analysis.
In the chip-multiprocessor (CMP) model, we are able to estimate the propagated
uncertainties with only 95 samples whereas Monte Carlo requires 5*10^4 samples
to achieve the similar accuracy. We also demonstrate the efficiency and
effectiveness of our method on a detailed DRAM subsystem.
