The nvidia monitoring library object pascal wrapper. Please, read the documentation for better understand what is nvml.

• Example on how to get nvidia driver version

var
  version: Ansistring;
begin
  try
    NvInitV2;
    version := NvSystemGetDriverVersion;
    if Length(version) = 0 then
    begin
      raise ENvSystemException.Create('Something may fail acquiring driver version. Length is zero');
    end;
    NvShutDown;
  except
    on E: ENvSystemException do
    begin
      NvShutDown;
      Fail(e.Message);
    end;
  end;

• Example on how to retrieve gpu temperature

var
  device: NvHandle;
  temp: Cardinal;
begin
  try
    NvInitV2;
    device := NvDeviceGetHandleByIndexV2(0);
    temp := NvDeviceGetTemperature(device, nvTemperatureGpu);
    NvShutDown;
  except
    On E: ENvSystemException do
    begin
      NvShutDown;
      Fail(e.Message);
    end;
  end;

• The wrapper is in working status. Below we have a list of migrated modules
