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
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 string in other
attribute names.
Where there is more than one GPU of a particular type,
the prefix string includes 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 string in
attribute names.
- -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 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,
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 string
at 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 string
at 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 not contain 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 str as the prefix string.
When this option is not specified,
the prefix string is 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.
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.
