Instructions

VBIOS-version

Forespørg VBIOS-versionen på hver enhed:

$ nvidia-smi --query-gpu=gpu_name,gpu_bus_id,vbios_version --format=csv

name, pci.bus_id, vbios_version
GRID K2, 0000:87:00.0, 80.04.D4.00.07
GRID K2, 0000:88:00.0, 80.04.D4.00.08

 

Query Description
timestamp The timestamp of where the query was made in format "YYYY/MM/DD HH:MM:SS.msec".
gpu_name The official product name of the GPU. 
This is an alphanumeric string. For all products.
gpu_bus_id PCI bus id as "domain:bus:device.function", in hex.
vbios_version The BIOS of the GPU board.

Forespørg GPU-metrikværdier til logføring på værtssiden

Denne forespørgsel er god til overvågning af GPU-metrikværdier på hypervisorsiden.

Denne forespørgsel fungerer for både ESXi og XenServer:

$ nvidia-smi --query-gpu=timestamp,name,pci.bus_id,driver_version,pstate,pcie.link.gen.max,
pcie.link.gen.current,temperature.gpu,utilization.gpu,utilization.memory,
memory.total,memory.free,memory.used --format=csv -l 5
Når du føjer yderligere parametre til en forespørgsel, skal du sørge for, at der ikke tilføjes mellemrum mellem forespørgselsindstillingerne.
Query Description
timestamp The timestamp of where the query was made in format "YYYY/MM/DD HH:MM:SS.msec".
name The official product name of the GPU. 
This is an alphanumeric string. For all products.
pci.bus_id PCI bus id as "domain:bus:device.function", in hex.
driver_version The version of the installed NVIDIA display driver. 
This is an alphanumeric string.
pstate The current performance state for the GPU. States range from P0 (maximum performance) to P12 (minimum performance).
pcie.link.gen.max The maximum PCI-E link generation possible with this GPU and system configuration. 
For example, if the GPU supports a higher PCIe generation than the system supports then this reports the system PCIe generation.
pcie.link.gen.current The current PCI-E link generation. These may be reduced when the GPU is not in use.
temperature.gpu Core GPU temperature. in degrees C.

utilization.gpu

Percent of time over the past sample period during which one or more kernels was executing on the GPU.
The sample period may be between 1 second and 1/6 second depending on the product.

utilization.memory

Percent of time over the past sample period during which global (device) memory was being read or written.
The sample period may be between 1 second and 1/6 second depending on the product.

memory.total

 Total installed GPU memory.

memory.free

 Total free memory.

memory.used

 Total memory allocated by active contexts.

nvidia-smi Brug til logning

Kortsigtet logning

Tilføj indstillingen "-f <filename>" for at omdirigere outputtet til en fil.

Prepend "timeout -t <seconds>" for at køre forespørgslen for <seconds> og stop med at logge.

Sørg for, at din forespørgsels granularitet er passende dimensioneret til den nødvendige brug:

 

Purpose nvidia-smi "-l" value interval timeout "-t" value Duration
Fine-grain GPU behavior 5 5 seconds 600 10 minutes
General GPU behavior 60 1 minute 3600 1 hour
Broad GPU behavior 3600 1 hour 86400 24 hours

 

Langsigtet skovhugst

Opret et shell-script for at automatisere oprettelsen af logfilen med tidsstempeldata føjet til filnavnet og forespørgselsparametrene.

Tilføj en brugerdefineret cron job til /var/spool/cron/crontabs for at kalde scriptet med de nødvendige intervaller.

YDERLIGERE KOMMANDOER PÅ LAVT NIVEAU, DER BRUGES TIL URE OG STRØM

Aktivér tilstanden "Persistens".

Alle indstillinger nedenfor for ure og strøm nulstilles mellem programkørsler, medmindre du aktiverer persistenstilstand (PM) for driveren.

Også den nvidia-smi Kommandoen kører hurtigere, hvis PM-tilstand er aktiveret.

nvidia-smi -pm 1 - Få ur, strøm og andre indstillinger til at fortsætte på tværs af programkørsler og driveraktiveringer.

Ure

Command Detail
nvidia-smi -ac <MEM clock, Graphics clock>   View clocks supported
nvidia-smi –q –d SUPPORTED_CLOCKS Set one of supported clocks
nvidia-smi -q –d CLOCK View current clock
