How to measure GPU usage?

Question

Using the top command in the terminal lists processes, sorted by their CPU usage (and you can change it to sort by another parameter)

Is there an equivalent for the GPU?

This fellow is asking about RAM used by GPU

Answer 1

For Nvidia GPUs there is a tool nvidia-smi that can show memory usage, GPU utilization and temperature of GPU.

For Intel GPU's you can use the intel-gpu-tools.

AMD has two options, fglrx (closed source drivers)

aticonfig --odgc --odgt

And for mesa (open source drivers), you can use RadeonTop .

Answer 2

Nvidia: to continuously update the output of nvidia-smi, you can use nvidia-smi --loop=1 (refresh interval of 1 second) or nvidia-smi --loop-ms=1000 (refresh interval of 1000 milliseconds).

   -l SEC, --loop=SEC
       Continuously  report  query data at the specified interval, rather than
       the default of  just  once.   The  application  will  sleep  in-between
       queries.   Note  that on Linux ECC error or XID error events will print
       out during the sleep period if the -x flag was not specified.  Pressing
       Ctrl+C at any time will abort the loop, which will otherwise run indef‐
       initely.  If no argument is specified for the -l form a default  inter‐
       val of 5 seconds is used.

   -lms ms, --loop-ms=ms
       Same as -l,--loop but in milliseconds.

Answer 3

You can use gpustat, which is a simple command-line script (wrapper for nvidia-smi) for querying and monitoring GPU status:

Answer 4

You can use the monitoring program glances with its GPU monitoring plug-in:

• open source
• to install: sudo apt-get install -y python-pip; sudo pip install glances[gpu]
• to launch: sudo glances

It also monitors the CPU, disk IO, disk space, network, and a few other things:

Answer 5

I use the following command:

nvidia-smi -l 2

and it gives me updates every 2 seconds.

Or :

watch -n0.1 "nvidia-settings -q GPUUtilization -q useddedicatedgpumemory"

And on AMD, use:

aticonfig --odgc --odgt

Answer 6

For Intel:

1. Install intel-gpu-tools (its likely that they are installed already)

sudo apt-get install intel-gpu-tools

2. Start the top like utility intel_gpu_top
3. Check your Stats and then exit with <Ctrl+C>

Thats what you get:
