How to use NVIDIA profiler

nvvp.md

Usually, located at /usr/local/cuda/bin

Non-Visual Profiler

$ nvprof python train_mnist.py

I prefer to use --print-gpu-trace.

$ nvprof --print-gpu-trace python train_mnist.py

Visual Profiler

On GPU machine, run

$ nvprof -o prof.nvvp python train_mnist.py

Copy prof.nvvp into your local machine

$ scp your_gpu_machine:/path/to/prof.nvvp .

Then, run nvvp (nvidia visual profiler) on your local machine:

$ nvvp prof.nvvp

It works more comfortably than X11 forwarding or something.

Thanks!

To help out other MacOS users in case they run into the same problem I did:

Make sure to point nvvp to a supported version of the JRE:

/Developer/NVIDIA/CUDA-10.1/bin/nvvp -vm /Library/Java/JavaVirtualMachines/jdk1.8.0_151.jdk/Contents/Home/jre/bin/java

Also make sure that the argument to -vm is an absolute path; it doesn't seem to understand relative paths.

@jrevels, Thank you!

There are also problems with the installation of the Cuda toolkit on Catalina. It can be solved by adding a link /Developer to any place. To do it on Catalina you need to add a line
Developer /Users/userName
to file /etc/synthetic.conf : like it is written here.

Hello, iam having problem on viewing the visual profiler. Every time it open upon selecting a file it returns a error, saying "The application being profilled returned a non-zero code"

Hello, do you know how to see GPU utilization with nvvp? I only see the duration of a function. But I want to also see the percentage of GPU utilization during a function.

i have to use the --profile-child-processes option to get the profile to work on windows.

I get no outputs using nvprof. No matter if I give arguments or not.
Doesn't work with .exe file build with VS2019, nor using nvprof python program.py.

Can you please help?

On Mac, nvvp prof.nvvp doesn't work.
An absolute path (instead of a relative path like "prof.nvvp") has to be provided.

My recommendation to anyone who wants to install nvvp on an up-to-date Mac (catalina) is not to even try.
Firstly you have to disable gatekeeper:
sudo spctl --master-disable
but then after you download nvvp it won't run because it wants an outdated java runtime (JRE) that's hard to get or install.
I still haven't figured it out.
Currently I'm trying to figure out how to do this, but it looks like it's very very painful.

Thanks man! Great help
