Use of NVIDIA Tools Extension under Visual Studio 2010 - visual-studio-2010

Question

I'm trying to use the NVIDIA Tools Extension to perform a more accurate performance assessment of a CUDA code with the Visual Profiler. I'm using Visual Studio 2010 for developing the code.
To setup Visual Studio 2010 for this feature, I have added
Properties -> Linker -> General -> Additional Library Directories -> $(NVTOOLSEXT_PATH)\lib\$(Platform);
Properties -> Linker -> General -> Input -> Additional Dependencies -> nvToolsExt32_1.lib;
However, when I use
#include <nvToolsExt>
the compiler says
Error 1 error C1083: Cannot open include file: 'nvToolsExt': No such file or directory
The environmental variable NVTOOLSEXT_PATH is set as
NVTOOLSEXT_PATH=C:\Program Files\NVIDIA GPU Computing Toolkit\nvToolsExt\
but the directory C:\Program Files\NVIDIA GPU Computing Toolkit\nvToolsExt\ is not present on my system and so I think that the NVIDIA Tools Extension is not installed.
I have two questions:
1) Is the above procedure to set up Visual Studio 2010 for the NVIDIA Tools Extension feature correct?
2) How to install the tools?
Thanks in advance.

Answer 1

In the Nsight User Guider for Visual Studio 2.2 \ NVIDIA Tools Extension Library \ Section 5. Adding NVTX to a Project has the following instructions:
The NVTX API is installed by the NVIDIA Nsight “host” installer (by
default) into the following location:
On a 32-bit system: C:\Program Files\NVIDIA GPU Computing
Toolkit\nvToolsExt
On a 64-bit system: C:\Program Files (x86)\NVIDIA GPU Computing
Toolkit\nvToolsExt
Both the header files and the library files themselves (.lib, .dll),
are located underneath this path.
By default, the NVIDIA Nsight installer will set up the environment
variable NVTOOLSEXT_PATH to point to the aforementioned location that
matches the system's bits.
5.1 C++ Project
In order to compile your project with NVTX support in Visual Studio,
use the following steps to setup your project accordingly:
Open the project properties dialog.
Navigate to Configuration > Properties > C/C++ > General.
Add the following path to the Additional Include Directories: $(NVTOOLSEXT_PATH)\include
Navigate to Configuration Properties > Linker > General.
Add the following path to the Additional Library Directories:
$(NVTOOLSEXT_PATH)\lib\$(Platform)
Navigate to Configuration > Properties > Linker > Input.
Add nvToolsExt32_1.lib or nvToolsExt64_1.lib (according to your system specifications), to the
Additional Dependencies.
5.2 CUDA (.cu file)
In case you use NVTX to annotate code in .cu files, please also make
sure the following configuration is setup (this is in addition to the
steps discussed in the previous section):
Open the project properties dialog. Navigate to Configuration Properties > CUDA C/C++ > Common. > Add the following path to the
Additional Include Directories: $(NVTOOLSEXT_PATH)\include
In the question you have skipped step 5.1.2 which adds NVTX to the Additional Include Paths. Without the updated include path the compiler will fail to find the NvToolsExt.h.
Section 5.3 and 5.4 recommend moving the NVTX library into your source tree (vs. using the default location) and adding a deploy to step to copy the DLLs to the project bin directory.
