       condor_gpu_discovery Output GPU-related ClassAd attributes

       condor_gpu_discovery -help

       condor_gpu_discovery [ <options>	]

       condor_gpu_discovery  runs  discovery  software to determine the	host's
       GPU capabilities, which are output as ClassAd attributes.

       This tool is not	available for MAC OS platforms.

       With no command line options, the single	ClassAd	attribute   DetectedG-
       PUs  is	printed.  If  the value	is 0, no GPUs were detected. If	one or
       more GPUS were detected,	the value is a string, presented  as  a	 comma
       and  space separated list of the	GPUs discovered, where each is given a
       name further used as the	prefix string in other attribute names.	 Where
       there  is more than one GPU of a	particular type, the prefix string in-
       cludes an integer value numbering  the  device;	these  integer	values
       monotonically increase from 0. For example, a discovery of two GPUs may

       DetectedGPUs="CUDA0, CUDA1"

       Further command line options use	 "CUDA"	either with or without one  of
       the integer values 0 or 1 as the	prefix string in attribute names.


	  Print	usage information and exit.


	  In  addition	to  the	 DetectedGPUs attribute, display standard CUDA
	  attributes. Each of these attribute names will have a	prefix	string
	  at  the  beginning of	its name. For a	host with more than one	of the
	  same GPU type, those attribute values	that are the same  across  all
	  of  the  GPUs	 will not have an integer value	in the prefix string .
	  The attributes are  Capability ,  DeviceName ,  DriverVersion	,  EC-
	  CEnabled  ,	GlobalMemoryMb	,  and	RuntimeVersion . The displayed
	  standard Open	CL attributes are  DeviceName ,	 ECCEnabled  ,	 Open-
	  CLVersion , and  GlobalMemoryMb .


	  Display  the	additional attributes of Each of these attribute names
	  will have a prefix string at the beginning of	its name.  ClockMhz  ,
	  ComputeUnits	, and  CoresPerCU for a	CUDA device, and  ClockMhz and
	  ComputeUnits for an OCL device.


	  Display attributes of	NVIDIA devices that change values as  the  GPU
	  is  working. Each of these attribute names will have a prefix	string
	  at the beginning of its name.	These are  FanSpeedPct ,  BoardTempC ,
	  DieTempC ,  EccErrorsSingleBit , and	EccErrorsDoubleBit .


	  When displaying attribute values, assume that	the machine has	a het-
	  erogeneous set of GPUs, so always include the	integer	value  in  the
	  prefix string	.

       -device _N_

	  Display  properties only for GPU device _N_ ,	where _N_ is the inte-
	  ger value defined for	the prefix string . Note  that	the  attribute
	  names	in this	output will not	contain	the value for _N_ .

       -tag string

	  Set  the resource tag	portion	of the intended	machine	ClassAd	attri-
	  bute	Detected<ResourceTag> to be string . If	 this  option  is  not
	  specified, the resource tag is  "GPUs" , resulting in	attribute name
	  DetectedGPUs .

       -prefix str

	  When naming attributes, use str as the prefix	string . When this op-
	  tion is not specified, the prefix string is either  CUDA or  OCL .


	  For testing purposes,	assume that N devices of type D	were detected.
	  No discovery software	is invoked. If D is 0, it refers to GeForce GT
	  330, and a default value for N is 1. If D is 1, it refers to GeForce
	  GTX 480, and a default value for N is	2.


	  Prefer detection via OpenCL rather than CUDA.	Without	 this  option,
	  CUDA	detection  software  is	 invoked first,	and no further Open CL
	  software is invoked if CUDA devices are detected.


	  Do only CUDA detection.


	  For Windows platforms	only, use a CUDA driver	rather than  the  CUDA
	  run time.


	  Output  in  the syntax of HTCondor configuration, instead of ClassAd
	  language. An additional  attribute  is  produced   NUM_DETECTED_GPUs
	  which	is set to the number of	GPUs detected.


	  For  interactive  use	 of the	tool, output extra information to show
	  detection while in progress.


	  Show diagnostic information, to aid in tool development.

Exit Status
       condor_gpu_discovery will exit with a status value  of  0  (zero)  upon
       success,	and it will exit with the value	1 (one)	upon failure.
