Tutorial Program
This tutorial will present the recently updated simulation infrastructure and related tools for GPGPU-Sim. GPGPU-Sim version 3.x represents a significant update to GPGPU-Sim featuring a more accurate and detailed microarchitecture model (including a configuration for NVIDIA's Fermi Architecture) and native NVIDIA ISA support. It also has a more modular software design that simplifies extensions for research.In this tutorial, we will introduce GPUWattch, a new power model for GPGPU-Sim that uses a modified version of McPAT. This power model is highly configurable and extensible, and has been validated with power measurements from real hardware GPUs.
More information about GPGPU-Sim can be found here.
