             Summary: GPU Scheduling - add an example discovery Script
                 Key: SPARK-27725
                 URL: https://issues.apache.org/jira/browse/SPARK-27725
             Project: Spark
          Issue Type: Story
          Components: Examples
    Affects Versions: 3.0.0
            Reporter: Thomas Graves


We should add an example script that can be used to discovery GPU's and output the correctly formatted JSON.

Something like below, but it needs to be tested on various systems with more then 2 gpu's:

ADDRS=`nvidia-smi --query-gpu=index --format=csv,noheader | sed 'N;s/\n/\",\"/'`
COUNT=`echo $ADDRS | tr -cd , | wc -c`
ALLCOUNT=`expr $COUNT + 1`
#echo \{\"name\": \"gpu\", \"addresses\":[\"$ADDRS\"]}
