Dear Ernst, elodw <[email protected]> writes:i want to start with pycuda and had a very beginner question: ok, the header lines are clear, same to_gpu statement and the get statement, thats it. What is the problem defined in Python: a=array[1000,100] for i in range(1000-1): for j in range(i+1,1000): calculate euclidean difference between a[i] and a[j] can i do this without using an extra kernel if i need a kernel how looks itI'm afraid, PyCUDA's arrays are not currently smart enough to do this, so you'll need to write your own kernel. I unfortunately can't write that for you, but you should be able to take a look at the CUDA docs and give it a shot. Hope that helps, Andreas
