cuda+mpi

Some people use cuda+mpi ?
How could you build your code with cuda+mpi !?
Ex: mpi.cpp + cuda.cu ? or only in .cu !?

I have 4 PC OS: Windows HPC Server 2008(x64)
Hardware : Tesla C1060 +Quadro NVS 295
compile tool : Visual Studio 2008 C++ with MSMPI library .
I run example by nvidia GPU Computing SDK (Device Query)

When only run Device Query , I get some message…

There are 2 devices supporting CUDA …
Device 0 : "Tesla C1060 "…
Device 1 : “Quadro NVS 295”…

But when I mpi+cuda , I get message…

Hi, I am CPU 0
There is no device supporting CUDA.
Device 0: “Device Emulation (CPU)”

What are you views ?
By the way…my Tesla C1060 driver software is Vista x64 because I could not fount the driver for Windows HPC Server 2008.
Is the driver reason !?

I already find the answer…
