Nomad Nvidia Device Plugin
This repository provides an implementation of a Nomad
device
plugin
for Nvidia GPUs.
Note: this package is currently embedded in Nomad itself but the Nomad team intends to externalize the driver.
Behavior
The Nvidia device plugin uses
NVML bindings to get data
regarding available Nvidia devices and will expose them via
Fingerprint
RPC. GPUs can be excluded from fingerprinting by setting the ignored_gpu_ids
field (see below). Plugin sends statistics for fingerprinted devices every
stats_period
period.
Config
The plugin is configured in the Nomad client's
plugin
block:
plugin "nvidia" {
config {
ignored_gpu_ids = ["uuid1", "uuid2"]
fingerprint_period = "5s"
}
}
The valid configuration options are:
ignored_gpu_ids
(list(string)
: []
): list of GPU UUIDs strings that
should not be exposed to nomad
fingerprint_period
(string
: "1m"
): interval to repeat the fingerprint
process to identify possible changes.
