gvprof's Introduction

GVProf

GVProf is a value profiler for NVIDIA GPUs to explore value-related inefficiencies in GPU-accelerated applications.

Quick Start

git clone --recursive [email protected]:Jokeren/GVProf.git && cd GVProf

# Install gvprof
./bin/install

# Setup environment variables
export GVProfInstall=$(pwd)/gvprof
export PATH=${GVProfInstall}/bin:$PATH
export PATH=${GVProfInstall}/hpctoolkit/bin:$PATH
export PATH=${GVProfInstall}/redshow/bin:$PATH

# If your GPU driver is greater than 470.57, this environment variable is necessary to set.
export SANITIZER_DISABLE_PARALLEL_LAUNCHES=1

# Test a sample
cd samples/vectorAdd.f32
make
gvprof -e redundancy ./vectorAdd
