cudpp in 4.1 ? Cannot find cudpp in 4.1

Hi I just upgraded to the cuda 4.1 toolkit and 4.1 SDK and I cannot find any header for cudpp anymore.

Does cudpp not exist anymore, and if so, what can I do to substitute its functionality.

Cudpp is no more included in the toolkit. You can still download it and compile it or use thrust.

As the release notes for the CUDA 4.1 point out, the uses of CUDPP in SDK examples have been replaced by Thrust. CUDPP is an open source project which can be found at

I hope that it gets maintained/optimized also in the future, because we use it extensively in our algorithms …
