-Once a job matches to a given slot, it needs to know which GPUs to use, if multiple are present.  GPUs that the job are permitted to use are specified in the slot {quote: ClassAd} as =AssignedGPUs=.  They are also published into the job's environment as =_CONDOR_AssignedGPUs=, and (if the configuration at the top is used) as =CUDA_VISIBLE_DEVICES= and =GPU_DEVICE_ORDINAL=. You can pass Assigned GPUs to your jobs arguments using the $$() syntax.  For example, if your job takes an argument "--device=X" where X is the device to use, you might do something like
+Once a job matches to a given slot, it needs to know which GPUs to use, if multiple are present.  GPUs that the job are permitted to use are specified as defined values for the slot ClassAd attribute =AssignedGPUs=.  They are also published into the job's environment with variable =_CONDOR_AssignedGPUs=. In addition, if the configuration is defined with =ENVIRONMENT_FOR_AssignedGPUs= set, environment variables =CUDA_VISIBLE_DEVICES= and =GPU_DEVICE_ORDINAL= are published. The =AssignedGPUs= attribute value can be passed as job arguments using the $$() substitution macro syntax.  For example, if the job takes an argument "--device=X" where X is the device to use, specify this in the submit description file with
 
 {code}
 arguments = "--device=$$(AssignedGPUs)"
 {endcode}
