       condor_gpu_discovery Output - GPU-related ClassAd attributes

Synopsis

       condor_gpu_discovery -help

       condor_gpu_discovery[<options>]

Description

       condor_gpu_discoveryruns  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  DetectedGPUs  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 stringin other attribute names. Where there is
       more than one GPU of a  particular  type,  the  prefix  stringincludes  an  integer  value
       numbering  the  device; these integer values monotonically increase from 0. For example, a
       discovery of two GPUs may output

       DetectedGPUs="CUDA0, CUDA1"

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

Options

       -help

          Print usage information and exit.

       -properties

          In  addition  to the  DetectedGPUs attribute, display standard CUDA attributes. Each of
          these attribute names will have a prefix stringat 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  ,   ECCEnabled  ,
          GlobalMemoryMb , and  RuntimeVersion . The displayed standard Open  CL  attributes  are
          DeviceName ,  ECCEnabled ,  OpenCLVersion , and  GlobalMemoryMb .

       -extra

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

       -dynamic

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

       -mixed

          When  displaying  attribute  values, assume that the machine has a heterogeneous 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 integer value  defined  for
          the  prefix  string.  Note  that the attribute names in this output will notcontain the
          value for <N>.

       -tag string

          Set  the  resource  tag   portion   of   the   intended   machine   ClassAd   attribute
          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 stras the prefix string. When this option is not specified,
          the prefix stringis either  CUDA or  OCL .

       -simulate:D,N

          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.

       -opencl

          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.

       -cuda

          Do only CUDA detection.

       -nvcuda

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

       -config

          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.

       -verbose

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

       -diagnostic

          Show diagnostic information, to aid in tool development.

Exit Status

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