{section: Advertise the GPU}
-The HTCondor =condor_gpu_discovery= tool is designed to assist in detecting GPUs and in configuring HTCondor to advertise 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. 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 use this mechanism to define a resource called 'GPUs'. This resource type name, 'GPUs,' is case insensitive, but you must be consistent about the plural. HTCondor considers 'GPU' to be a different resource type than 'GPUs'. We recommend the use of 'GPUs' for GPU custom resources.
