PyProf - PyTorch Profiling tool
===============================

**ANNOUNCEMENT: The default branch for PyProf has changed to 'main'. Please
update all pulls and PRs accordingly.**

**LATEST RELEASE: You are currently working on the main branch which
tracks under-development progress towards the next release. The
latest release of the PyProf is 3.8.0 and is available on branch** `r21.02
<https://github.com/NVIDIA/PyProf/blob/r21.02>`_.
**NOTE: You are currently on the 21.04 branch which tracks stabilization
towards the release. This branch is not usable during stabilization**

.. overview-begin-marker-do-not-remove
PyProf is a tool that profiles and analyzes the GPU performance of PyTorch
models. PyProf aggregates kernel performance from `Nsight Systems
<https://developer.nvidia.com/nsight-systems>`_ or `NvProf
<https://developer.nvidia.com/nvidia-visual-profiler>`_ and provides the
following additional features:

* Identifies the layer that launched a kernel: e.g. the association of
`ComputeOffsetsKernel` with a concrete PyTorch layer or API is not obvious.

* Identifies the tensor dimensions and precision: without knowing the tensor
dimensions and precision, it's impossible to reason about whether the actual
(silicon) kernel time is close to maximum performance of such a kernel on
the GPU. Knowing the tensor dimensions and precision, we can figure out the
FLOPs and bandwidth required by a layer, and then determine how close to
maximum performance the kernel is for that operation.

* Forward-backward correlation: PyProf determines what the forward pass step
is that resulted in the particular weight and data gradients (wgrad, dgrad),
which makes it possible to determine the tensor dimensions required by these
backprop steps to assess their performance.

* Determines Tensor Core usage: PyProf can highlight the kernels that use
`Tensor Cores <https://developer.nvidia.com/tensor-cores>`_.

* Correlate the line in the user's code that launched a particular kernel (program trace).

.. overview-end-marker-do-not-remove
The current release of PyProf is 3.8.0 and is available in the 21.02 release of
the PyTorch container on `NVIDIA GPU Cloud (NGC) <https://ngc.nvidia.com>`_. The
branch for this release is `r21.02
<https://github.com/NVIDIA/PyProf/tree/r21.02>`_.

The User Guide can be found in the
`documentation for current release
<https://docs.nvidia.com/deeplearning/frameworks/pyprof-user-guide/index.html>`_, and
provides instructions on how to install and profile with PyProf.

A complete `Quick Start Guide <https://docs.nvidia.com/deeplearning/frameworks/pyprof-user-guide/quickstart.html>`_
provides step-by-step instructions to get you quickly started using PyProf.

An `FAQ <https://docs.nvidia.com/deeplearning/frameworks/pyprof-user-guide/faqs.html>`_ provides
answers for frequently asked questions.

The `Release Notes
<https://docs.nvidia.com/deeplearning/frameworks/pyprof-release-notes/index.html>`_
indicate the required versions of the NVIDIA Driver and CUDA, and also describe
which GPUs are supported by PyProf

the `Contributing <CONTRIBUTING.md>`_ document.

Reporting problems, asking questions
------------------------------------

We appreciate any feedback, questions or bug reporting regarding this
project. When help with code is needed, follow the process outlined in
the Stack Overflow (https://stackoverflow.com/help/mcve)
document. Ensure posted examples are:

* minimal – use as little code as possible that still produces the
same problem

* complete – provide all parts needed to reproduce the problem. Check
if you can strip external dependency and still show the problem. The
less time we spend on reproducing problems the more time we have to
fix it

* verifiable – test the code you're about to provide to make sure it
reproduces the problem. Remove all other problems that are not
related to your request/question.
