CUPTI API in Cuda 4.0

CUDA Toolkit 4.0 Feature and Overview Webinar says CUDA Performance Tool Interface (CUPTI) as new a feature included in cuda 4.0, but I can’t find any code or document about it in CUDA Toolkit 4.0.

The CUPTI API is designed to help performance analysis tools ISVs add support for GPUs their products (e.g. TAU-CUDA, Vampir Trace, etc.)

CUPTI should not be incorporated into your application directly (unless it’s a performance analysis tool).

CUPTI libs and documentation are available in as a separate download called the “CUDA Tools SDK”, on the same page where you download the CUDA Toolkit:
