Positivity Bounds on Effective Field Theories: Galileon Theories as a Case Study
, M.Sc. Thesis Sharif University of Technology ; Torabian, Mahdi (Supervisor)
Abstract
Effective field theory is a practical method for model building and explaining experimental/observational data. These theories are constructed based on knowing low energy degrees of freedom and symmetries (accidental or fundamental). By construction, these theories are applicable up to a cut-off scale and their predictions beyond that are not reliable. For applications to higher energies a UV completion is needed through which modifications are applied or new heavy degrees of freedom are introduced. In order to complete a theory in a Wilsonian approach, scattering amplitudes must satisfy some constraints. These constraints are derived from basic assumptions like Lorentz invariance,...
An Intelligent L2 Management Method in GPUs
, M.Sc. Thesis Sharif University of Technology ; Sarbazi Azad, Hamid (Supervisor)
Abstract
To capture on-chip memory locality, tolerate off-chip memory latency, and expeditiously process memory-bound GPGPU applications, Graphics Processing Units (GPUs) introduce a local L1D cache and a shared L2 cache within and between streaming multiprocessors (SMs), respectively. The L2 cache solves the problem of data coherency and sharing between SMs (unlike the L1D cache). Prior work shows that loading all data into the L2 cache without a proper mechanism to manage the input data rate, poses some challenges (e.g., cache contention/trashing, increased write-back traffic, and bandwidth inefficiency) and ultimately puts a lot of pressure on off-chip memory. In this paper, we make the...
