slurm_gpustat: A Python repository from albanie

slurm_gpustat

Note: I no longer have access to a slurm cluster, so this tool is no longer actively maintained

slurm_gpustat is a simple command line utility that produces a summary of GPU usage on a slurm cluster. The tool can be used in two ways:

To query the current usage of GPUs on the cluster.
To launch a daemon which will log usage over time. This log can later be queried to provide usage statistics.

Installation

Install via pip install slurm_gpustat. If you prefer to hack around with the source code, it's a single python file.

Usage

To print a summary of current activity:

slurm_gpustat

To print a summary of current activity on particular partitions, e.g. debug & normal:

slurm_gpustat -p debug,normal or slurm_gpustat --partition debug,normal

To start the logging dameon:

slurm_gpustat --action daemon-start

To view a summary of logged data:

    `slurm_gpustat --action history`

Example outputs

Running slurm_gpustat will produce something like this:

----------------------
Under SLURM management
----------------------
There are a total of 12 gpus [up]
3 rtx6k gpus
2 v100 gpus
3 m40 gpus
4 p40 gpus
----------------------
There are a total of 10 gpus [accessible]
1 rtx6k gpus
2 v100 gpus
3 m40 gpus
4 p40 gpus
----------------------
Usage by user:
user1     [total: 1 ] m40: 1
user2     [total: 1 ] p40: 1
user3     [total: 3 ] p40: 3
----------------------
There are 5 gpus available:
p40: 0
rtx6k: 1
v100: 2
m40: 2

Adding --verbose to this command will produce a more detailed breakdown for the section describing gpus that are still available. Example output:

There are 18 gpus available:

Running slurm_gpustat --action history (after the daemon has run for a little while) will produce something like this:

Historical data contains 7 samples (2020-01-03 11:51:43 to 2020-01-03 11:51:45)
GPU usage for user1:
v100  > avg: 2, max: 4
m40   > avg: 1, max: 1
total > avg: 3

GPU usage for user2:
p40m  > avg: 3, max: 4
total > avg: 3
