Code optimization with GPU
显示 更早的评论
Hi everyone, I have the following line of codes which I would like to parallelize on the GPU :
U = zeros(q, M, q, 'gpuArray');
for j=1:q
U(j,:,j) = my_line_vector;
end
Is there any way to suppress the loop?
Thes are the lines of code that run the slowest in my program.
Thank you in advance
Michel

I = reshape(gpuArray.eye(q),q,1,q);
U = I.*my_line_vector;

Ah yes, sorry about that. I've edited the original, see if that works.
