SST Learning Note

Before all Key interfaces 1. SST::Component: basic class for simulation objects 2. SST::Event: interactions between components or recurring events like component clock ticks 1. Event class can have handler with form of void func(Event* ev). The handler will invoke a given member function whenever triggered. 2. The

SURF Week 6-9: AMD GCN3 Traces and Accel-Sim

Okay this is a rather long post, which covers what I did in the past four weeks to run the AMD GCN3 traces on Accel-Sim. The plan was to map AMD GCN3 instructions into the Accel-Sim trace-driven part to my best knowledge with the help of its official ISA manual.

SURF Week 4 - 5: Trace format and MGPUSim Investigation

So for my research project, we need to generate hardware traces from AMD GPU hardware. However, due to limitations of software tool, if we want to do it, we would have to make modification to the JIT compiler of vISA and mISA, which is way beyond my current knowledge. Instead,

SURF Week 3: AMD GPU Hardware Tracing Tools

Since my research involves aquiring actual hardware traces executed by the AMD GPUs, I looked for tools provided by AMD ROCm platform initially to see if there are tools like the NVIDIA NVBit that could be used for instrumentation. Unfortunately, AMD as of current time does not have such tool,

SURF Week 2: First Taste on GPU Simulator

This week, what I did primarily is to familiarize with the existing GPGPU-Sim framework and run certain tests on it. Instead of focusing on the lower level details like how to run the simulator (which is available in the handout), I would like to discuss some thoughts on the GPU

SURF Week 1: GPU Architecture and CUDA Introduction

Since the SURF project I enrolled in involving works related to GPU, the first series of tasks assigned to me were to get familiar with GPU and CUDA programming as I did not have previous experience on these two topics. This article will thus serve as a summary for what

SURF Week 0: Getting started with Accel-Sim

During the summer period this year, I will participate in the Purdue University SURF program and working in the Accel-Sim project, so I feel like to compose a weekly development blog series to keep track of challenges and insights gained from the research process. This article is like the summary
