*Interface*

gpu_configuration(source text) –- optional param. Can be one of 'tensorflow' and 'nvidia'. Default to 'tensorflow'

SELECT * FROM madlib.gpu_configuration();

SELECT * FROM madlib.gpu_configuration('tensorflow');

SELECT * FROM madlib.gpu_configuration('nvidia');

 

*GPDB*

List the state of the cluster, however it is configured:

SELECT * FROM madlib.gpu_configuration();

NVIDIA Tesla P100 | host1

NVIDIA Tesla P100 | host1

Super Duper GPU   | host2

Super Duper GPU   | host2
