cutil.h CUT_SAFE_CALL in CUDA 4.0

I am using CUDA 4.0 . I am trying to use the following functions.

CUT_DEVICE_INIT();
CUT_SAFE_CALL(cutCreateTimer(&hTimer));

I included cutil.h to use the above functions. But the compiler reports t开发者_开发问答he following..

fatal error C1083: Cannot open include file: 'cutil.h': No such file or directory

I searched in the CUDA directory but there is no file 'cutil.h'. How can I find the time needed for a CUDA function using the above method? (not using the C++ timer)

You probably didn't tell your compiler where to find the file. I can't tell you exactly because you didn't provide details on what system you are using but for example, on Windows XP and assuming a default installation of version 4.0 of the SDK the cutil.h header file is in:

C:\Documents and Settings\All Users\Application Data\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\common\inc

For Windows 7 I think it is:

C:\Program Data\NVIDIA Corporation\NVIDIA GPU Computing SDK 4.0\C\common\inc

but not sure.
