Return Values


When you pass the logical ID of an AWS::Batch::JobDefinition resource to the intrinsic Ref function, the function returns the job definition ARN, such as arn:aws:batch:us-east-1:111122223333:job-definition/test-gpu:2.

For more information about using the Ref function, see Ref.


Test nvidia-smi

The following example tests the nvidia-smi command on a GPU instance to verify that the GPU is working inside the container. For more information, see Test GPU Functionality in the AWS Batch User Guide.
