Detailed Description

       This chapter describes the queries that NVML can perform against the local system. These
       queries are not device-specific.

Function Documentation

   nvmlReturn_t DECLDIR nvmlSystemGetCudaDriverVersion (int * cudaDriverVersion)
       Retrieves the version of the CUDA driver.

       For all products.

       The returned CUDA driver version is the same as the CUDA API cuDriverGetVersion() would
       return on the system.

       Parameters:
           cudaDriverVersion Reference in which to return the version identifier

       Returns:

           • NVML_SUCCESS if cudaDriverVersion has been set

           • NVML_ERROR_INVALID_ARGUMENT if cudaDriverVersion is NULL

   nvmlReturn_t DECLDIR nvmlSystemGetDriverVersion (char * version, unsigned int length)
       Retrieves the version of the system's graphics driver.

       For all products.

       The version identifier is an alphanumeric string. It will not exceed 80 characters in
       length (including the NULL terminator). See
       nvmlConstants::NVML_SYSTEM_DRIVER_VERSION_BUFFER_SIZE.

       Parameters:
           version Reference in which to return the version identifier
           length The maximum allowed length of the string returned in version

       Returns:

           • NVML_SUCCESS if version has been set

           • NVML_ERROR_UNINITIALIZED if the library has not been successfully initialized

           • NVML_ERROR_INVALID_ARGUMENT if version is NULL

           • NVML_ERROR_INSUFFICIENT_SIZE if length is too small

   nvmlReturn_t DECLDIR nvmlSystemGetNVMLVersion (char * version, unsigned int length)
       Retrieves the version of the NVML library.

       For all products.

       The version identifier is an alphanumeric string. It will not exceed 80 characters in
       length (including the NULL terminator). See
       nvmlConstants::NVML_SYSTEM_NVML_VERSION_BUFFER_SIZE.

       Parameters:
           version Reference in which to return the version identifier
           length The maximum allowed length of the string returned in version

       Returns:

           • NVML_SUCCESS if version has been set

           • NVML_ERROR_INVALID_ARGUMENT if version is NULL

           • NVML_ERROR_INSUFFICIENT_SIZE if length is too small

   nvmlReturn_t DECLDIR nvmlSystemGetProcessName (unsigned int pid, char * name, unsigned int
       length)
       Gets name of the process with provided process id

       For all products.

       Returned process name is cropped to provided length. name string is encoded in ANSI.

       Parameters:
           pid The identifier of the process
           name Reference in which to return the process name
           length The maximum allowed length of the string returned in name

       Returns:

           • NVML_SUCCESS if name has been set

           • NVML_ERROR_UNINITIALIZED if the library has not been successfully initialized

           • NVML_ERROR_INVALID_ARGUMENT if name is NULL or length is 0.

           • NVML_ERROR_NOT_FOUND if process doesn't exists

           • NVML_ERROR_NO_PERMISSION if the user doesn't have permission to perform this
             operation

           • NVML_ERROR_UNKNOWN on any unexpected error
