Accel-Sim

Accel-Sim is a simulation framework for simulating and validating programmable accelerators like GPUs.

Accel-Sim Overview

  1. Accel-Sim Tracer: An NVBit tool for generating SASS traces from CUDA applications.

  2. Accel-Sim SASS Frontend: A simulator frontend that consumes SASS traces and feeds them into a performance model. The intial release of Accel-Sim coincides with the release of GPGPU-Sim 4.0, which acts as the detailed performance model.

  3. Accel-Sim Correlator: A tool that matches, plots and correlates statistics from the performance model with real hardware statistics generated by profiling tools.

  4. Accel-Sim Tuner: An automated tuner that automates configuration file generation from a detailed microbenchmark suite.
