Print messages in PyCUDA

Question

In simple CUDA programs we can print messages by threads by including cuPrintf.h but doing this in PyCUDA is not explained anywhere. How to do this in PyCUDA?

Answer 1

On Compute Capability 2.0 and later GPUs, cuPrintf.h is discouraged in favor of just using CUDA's built-in printf(). To use it, just #include <stdio.h> and call printf() just like on the host.

The PyCUDA wiki has a specific example of this.
