GPU Management and Monitoring
|
|
=============================
|
|
|
|
The ``nvidia-smi`` command provided by NVIDIA can be used to manage and monitor GPUs enabled Compute Nodes. In conjunction with the xCAT``xdsh`` command, you can easily manage and monitor the entire set of GPU enabled Compute Nodes remotely from the Management Node.
|
|
|
|
Example: ::
|
|
|
|
# xdsh <noderange> "nvidia-smi -i 0 --query-gpu=name,serial,uuid --format=csv,noheader"
|
|
node01: Tesla K80, 0322415075970, GPU-b4f79b83-c282-4409-a0e8-0da3e06a13c3

**Note: The following commands are provided as convenience.** *Always consult the nvidia-smi manpage for the latest supported functions.*

|
|
|
Management
|
|
----------
|
|
|
|
Some useful ``nvidia-smi`` example commands for management.
|
|
|
|
|
|
* Set persistence mode, When persistence mode is enabled the NVIDIA driver remains loaded even when no active clients, DISABLED by default::
|
|
|
|
nvidia-smi -i 0 -pm 1
|
|
|
|
* Disabled ECC support for GPU. Toggle ECC support, A flag that indicates whether ECC support is enabled, need to use --query-gpu=ecc.mode.pending to check [Reboot required]::
|
|
|
|
nvidia-smi -i 0 -e 0
|
|
|
|
* Reset the ECC volatile/aggregate error counters for the target GPUs::
|
|
|
|
nvidia-smi -i 0 -p 0/1
|
|
|
|
* Set MODE for compute applications, query with --query-gpu=compute_mode::
|
|
|
|
nvidia-smi -i 0 -c 0/1/2/3
|
|
|
|
* Trigger reset of the GPU ::
|
|
|
|
nvidia-smi -i 0 -r
|
|
|
|
* Enable or disable Accounting Mode, statistics can be calculated for each compute process running on the GPU, query with -query-gpu=accounting.mode::
|
|
|
|
nvidia-smi -i 0 -am 0/1
|
|
|
|
* Specifies maximum power management limit in watts, query with --query-gpu=power.limit ::
|
|
|
|
nvidia-smi -i 0 -pl 200
|
|
|
|
Monitoring
|
|
----------
|
|
|
|
Some useful ``nvidia-smi`` example commands for monitoring.
|
|
|
|
* The number of NVIDIA GPUs in the system ::
|
|
|
|
nvidia-smi --query-gpu=count --format=csv,noheader
|
|
|
|
* The version of the installed NVIDIA display driver ::
|
|
|
|
nvidia-smi -i 0 --query-gpu=driver_version --format=csv,noheader
|
|
|
|
* The BIOS of the GPU board ::
|
|
|
|
nvidia-smi -i 0 --query-gpu=vbios_version --format=csv,noheader
|
|
|
|
* Product name, serial number and UUID of the GPU::
|
|
|
|
nvidia-smi -i 0 --query-gpu=name,serial,uuid --format=csv,noheader
|
|
|
|
* Fan speed::
|
|
|
|
nvidia-smi -i 0 --query-gpu=fan.speed --format=csv,noheader
|
|
|
|
* The compute mode flag indicates whether individual or multiple compute applications may run on the GPU. (known as exclusivity modes) ::
|
|
|
|
nvidia-smi -i 0 --query-gpu=compute_mode --format=csv,noheader
|
|
|
|
* Percent of time over the past sample period during which one or more kernels was executing on the GPU::
|
|
|
|
nvidia-smi -i 0 --query-gpu=utilization.gpu --format=csv,noheader
|
|
|
|
* Total errors detected across entire chip. Sum of device_memory, register_file, l1_cache, l2_cache and texture_memory ::
|
|
|
|
nvidia-smi -i 0 --query-gpu=ecc.errors.corrected.aggregate.total --format=csv,noheader
|
|
|
|
* Core GPU temperature, in degrees C::
|
|
|
|
nvidia-smi -i 0 --query-gpu=temperature.gpu --format=csv,noheader
|
|
|
|
* The ECC mode that the GPU is currently operating under::
|
|
|
|
nvidia-smi -i 0 --query-gpu=ecc.mode.current --format=csv,noheader
|
|
|
|
* The power management status::
|
|
|
|
nvidia-smi -i 0 --query-gpu=power.management --format=csv,noheader
|
|
|
|
* The last measured power draw for the entire board, in watts::
|
|
|
|
nvidia-smi -i 0 --query-gpu=power.draw --format=csv,noheader
|
|
|
|
* The minimum and maximum value in watts that power limit can be set to ::
|
|
|
|
nvidia-smi -i 0 --query-gpu=power.min_limit,power.max_limit --format=csv
|
