I'm writing a clone of Waitfu2x using OpenCL, which would allow us poor windows users to enjoy our waifus without having to use the web site (and without resolution restrictions).

After a long and unfair fight, I got my GTX970 to scale a 667x1000 image to 1334x2000 in about 40 seconds, which is a great improvement over waifu2x-converter-cpp that does th same thing in about 3 minutes.

But your web site does it in about four seconds.

Does that mean there is a large room for improvement for me, or do you run a large cluster of videocards on your site?

waifu2x.udp.jp is hosted on EC2 g2.8xlarge instance. g2.8xlarge has four GRID K520. The one of API thread uses a single GPU. There are four API thread on server. And, waifu2x-converter-cpp modified by tanakamura has already supported OpenCL/FMA/AVX/CUDA. It might be faster than Torch implementation.
