| # This script is a basic example script to get resource information about NVIDIA GPUs. |
| # It assumes the drivers are properly installed and the nvidia-smi command is available. |
| # It is not guaranteed to work on all setups so please test and customize as needed |
| # for your environment. It can be passed into SPARK via the config |
| # spark.{driver/executor}.resource.gpu.discoveryScript to allow the driver or executor to discover |
| # the GPUs it was allocated. It assumes you are running within an isolated container where the |
| # GPUs are allocated exclusively to that driver or executor. |
| # It outputs a JSON formatted string that is expected by the |
| # spark.{driver/executor}.resource.gpu.discoveryScript config. |
| # |
| # Example output: {"name": "gpu", "addresses":["0","1","2","3","4","5","6","7"]} |
