# Ricks-Lab GPU Utilities

## rickslab-gpu-utils

A set of utilities for monitoring GPU performance and modifying control settings.

In order to get maximum capability of these utilities, you should be running with a kernel that
provides support of the GPUs you have installed.  If using AMD GPUs, installing the latest amdgpu
driver package or the latest ROCm release, may provide additional capabilities. If you have Nvidia
GPUs installed, you should have `nvidia-smi` installed in order for the utility reading of the cards
to be possible.  Writing to GPUs is currently only possible for AMD GPUs, and only with compatible
cards and with the the AMD ppfeaturemask set to 0xfffd7fff. This can be accomplished by adding
`amdgpu.ppfeaturemask=0xfffd7fff` to the `GRUB_CMDLINE_LINUX_DEFAULT` value in
`/etc/default/grub` and executing `sudo update-grub`

Check out the [User Guide](https://github.com/Ricks-Lab/gpu-utils/blob/master/docs/USER_GUIDE.md)!

Install the latest package from [PyPI](https://pypi.org/project/rickslab-gpu-utils/) with the following
commands:

```
pip3 uninstall rickslab-gpu-utils
pip3 install rickslab-gpu-utils
```

## gpu-chk

This utility verifies if the environment is compatible with **rickslab-gpu-utils**.

## gpu-ls

This utility displays most relevant parameters for installed and compatible GPUs. The
default behavior is to list relevant parameters by GPU.  OpenCL platform information is
added when the *--clinfo* option is used.  A brief listing of key parameters is available
with the *--short* command line option.  A simplified table of current GPU state is
displayed with the *--table* option. The *--no_fan* can be used to ignore fan settings.
The *--pstate* option can be used to output the p-state table for each GPU instead of
the list of basic parameters.  The *--ppm* option is used to output the table of available
power/performance modes instead of basic parameters.

## gpu-mon

A utility to give the current state of all compatible GPUs. The default behavior
is to continuously update a text based table in the current window until Ctrl-C is
pressed.  With the *--gui* option, a table of relevant parameters will be updated
in a Gtk window.  You can specify the delay between updates with the *--sleep N*
option where N is an integer > zero that specifies the number of seconds to sleep
between updates.  The *--no_fan* option can be used to disable the reading and display
of fan information.  The *--log* option is used to write all monitor data to a psv log
file.  When writing to a log file, the utility will indicate this in red at the top of
the window with a message that includes the log file name. The *--plot* will display a
plot of critical GPU parameters which updates at the specified *--sleep N* interval. If
you need both the plot and monitor displays, then using the --plot option is preferred
over running both tools as a single read of the GPUs is used to update both displays.
The *--ltz* option results in the use of local time instead of UTC.

## gpu-plot

A utility to continuously plot the trend of critical GPU parameters for all compatible
GPUs. The *--sleep N* can be used to specify the update interval.  The *gpu-plot*
utility has 2 modes of operation.  The default mode is to read the GPU driver
details directly, which is useful as a standalone utility.  The *--stdin* option
causes *gpu-plot* to read GPU data from stdin.  This is how *gpu-mon* produces the
plot and can also be used to pipe your own data into the process.  The *--simlog*
option can be used with the *--stdin* when a monitor log file is piped as stdin.
This is useful for troubleshooting and can be used to display saved log results.
The *--ltz* option results in the use of local time instead of UTC.  If you plan
to run both *gpu-plot* and *gpu-mon*, then the *--plot* option of the *gpu-mon*
utility should be used instead of both utilities in order reduce data reads by
a factor of 2.

## gpu-pac

Program and Control compatible GPUs with this utility.  By default, the commands to
be written to a GPU are written to a bash file for the user to inspect and run.  If you
have confidence, the *--execute_pac* option can be used to execute and then delete the
saved bash file.  Since the GPU device files are writable only by root, sudo is used to
execute commands in the bash file, as a result, you will be prompted for credentials in the
terminal where you executed *gpu-pac*. The *--no_fan* option can be used to eliminate
fan details from the utility. The *--force_write* option can be used to force all configuration
parameters to be written to the GPU.  The default behavior is to only write changes.

## New in this Release -  [v3.5.0](https://github.com/Ricks-Lab/amdgpu-utils/releases/tag/v3.5.0)

* Utilities now include reading of NV GPUs with full gpu-ls, gpu-mon, and gpu-plot support!
* Update name from **amdgpu-utils** to **rickslab-gpu-utils**.
* Improved PyPI packaging.
* Updated User Guide to cover latest features and capabilities.
* Improved robustness of NV read by validating sensor support for each query item the first time read.  This will assure functionality on older model GPUs.
* Fixed issue in setting display model name for NV GPUs.
* Improved how lack of voltage readings for NV is handled in the utilities.
* Fixed an issue in assessing compute capability when GPUs of multiple vendors are installed.

## Development Plans

* Optimize plot utilities for performance.
* Add status read capabilities for Intel GPUs.
* Add pac capabilities for Nvidia GPUs.

## Known Issues

* I/O error when selecting CUSTOM ppm.  Maybe it requires arguments to specify the custom configuration.
* Doesn't work well with Fiji ProDuo cards.
* P-state mask gets intermittently reset for GPU used as display output.
* Utility *gpu-pac* doesn't show what the current P-state mask is.  Not sure if that can be read back.
* Utility *gpu-pac* fan speed setting results in actual fan speeds a bit different from setting and pac interface shows actual values instead of set values.
