Will impact all GPUs unless a single GPU is specified using the -i argument. See the ( GPU ATTRIBUTES) section for a description of ECC mode. After each reboot persistence mode will default to "Disabled". ![]() However, it does not persist across reboots. The effect of this operation is immediate. See the ( GPU ATTRIBUTES) section for a description of persistence mode. Set the persistence mode for the target GPUs. It is recommended that users desiring consistency use either UUID or PCI bus ID, since device enumeration ordering is not guaranteed to be consistent between reboots andīoard serial number might be shared between multiple GPUs on the same board.ĭEVICE MODIFICATION OPTIONS -pm, -persistence-mode=MODE The specified id may be the GPU's 0-based index in the natural enumeration returned by the driver, the GPU's board serial number, the GPU's UUID, or the GPU's PCI bus ID nounits - don't print units for numerical valuesĭisplay data for a single specified GPU.noheader - skip first line with column headers.csv - comma separated values (MANDATORY).Call -help-query-retired-pages for more info. List of GPU device memory pages that have been retired. Call -help-query-accounted-apps for more info. Call -help-query-compute-apps for more info. List of currently active compute processes. Call -help-query-supported-clocks for more info. Pass comma separated list of properties you want to query. If no argument is specified for the -l form a default interval ofĪllows the caller to pass an explicit list of properties to query. Pressing Ctrl+C at any time will abort the loop, which will otherwise run indefinitely. Note that on Linux ECC error or XID error events will print outĭuring the sleep period if the -x flag was not specified. The application will sleep in-between queries. Doesn't work with -u/-unit or -x/-xml-format flags.Ĭontinuously report query data at the specified interval, rather than the default of just once. Sampling data with max, min and avg is also returned for POWER, UTILIZATION and CLOCK display types. Embed the DTD in the XML output.ĭisplay only selected information: MEMORY, UTILIZATION, ECC, TEMPERATURE, POWER, CLOCK, COMPUTE, PIDS, PERFORMANCE, SUPPORTED_CLOCKS, PAGE_RETIREMENT, ACCOUNTING Flags can be combined with comma e.g. Both GPU and Unit query outputs conform to corresponding DTDs. ![]() ![]() Produce XML output in place of the default human-readable format. Redirect query output to the specified file in place of the default stdout. Reboots and board serial number might be shared between multiple GPUs on the same board. It is recommended that users desiring consistency use either UUID or PCI bus ID, since device enumeration ordering is not guaranteed to be consistent between PCI bus ID (as domain:bus:device.function in hex). The specified id may be the GPU/Unit's 0-based index in the natural enumeration returned by the driver, the GPU's board serial number, the GPU's UUID, or the GPU's Unit data is only available for NVIDIA S-class Tesla enclosures.ĭisplay data for a single specified GPU or Unit. Use the -i option to restrict the output to a single GPU or Unit.ĭisplay Unit data instead of GPU data. By default information for all available GPUs or Units is displayed. Some devices and/or environments don't support all possible information.Īny unsupported data is indicated by a "N/A" in the output. Displayed info includes all data listed in the ( GPU ATTRIBUTES) or ( UNIT ATTRIBUTES) sections of this document. List each of the NVIDIA GPUs in the system, along with their UUIDs.ĭisplay GPU or Unit info. NVML SDK: Python bindings: OPTIONS GENERAL OPTIONS -h, -help However, both NVML and the Python bindings are backwards compatible, and should be the first choice when writing any tools that must be maintained The output of NVSMI is not guaranteed to be backwards compatible. See the NVIDIA developer website link below for more information about NVML. Note that much of the functionality of NVSMI is provided by the underlying NVML C-based library. Metrics can be consumedĭirectly by users via stdout, or provided by file via CSV and XML formats for scripting purposes. NVSMI is a cross platform tool that supports all standard NVIDIA driver-supported Linux distros, as well as 64bit versions of Windows starting with Windows Server 2008 R2. Very limited information is also provided for ![]() Nvidia-smi (also NVSMI) provides monitoring and management capabilities for each of NVIDIA's Tesla, Quadro and GRID devices from Fermi and higher architecture families.
