     * Retrieves the device boardId from 0-N.
     * Devices with the same boardId indicate GPUs connected to the same PLX.  Use in conjunction with
     *  \ref nvmlDeviceGetMultiGpuBoard() to decide if they are on the same board as well.
     *  The boardId returned is a unique ID for the current configuration.  Uniqueness and ordering across
     *  reboots and system configurations is not guaranteed (i.e. if a Tesla K40c returns 0x100 and
     *  the two GPUs on a Tesla K10 in the same system returns 0x200 it is not guaranteed they will
     *  always return those values but they will always be different from each other).
