{section: Advertise the GPU}
-The availability of GPU resources must be advertised in the machine's ClassAd, in order for jobs that need GPUs to be matched with machines that have GPUs. The HTCondor _condor_gpu_discovery_ tool is designed to assist in detecting GPUs and in providing configuration details that help to set up the advertisement of GPU information.
+The availability of GPU resources must be advertised in the machine's ClassAd, in order for jobs that need GPUs to be matched with machines that have GPUs.
+
+As of HTCondor 8.2 (actually 8.1.6), you can detect and advertise GPUs by adding a single line to the configuration file on your STARTD.
+
+ use feature : GPUs
+
+You can advertise additional attributes of the GPUs by also setting
+
+ GPU_DISCOVERY_EXTRA = -extra
+
+The =feature:GPUs= metaknob (above) will invoke the _condor_gpu_discovery_ tool
+to populate a custom resource identified by 'GPUs' in the following way.

+The HTCondor _condor_gpu_discovery_ tool is designed to assist in detecting GPUs and in providing configuration details that help to set up the advertisement of GPU information.
This tool detects CUDA and OpenCL devices, and it outputs a list of GPU identifiers for all detected devices.
HTCondor has a general mechanism for declaring user-defined slot resources. GPUs are a user-defined slot resource, so this mechanism is used to define a resource. These examples use the resource type name =GPUs=. These resource type names are case insensitive, but all characters within the name are significant,
