Then I tested Intel(R) OpenCL HD Graphics with fractal-gen-opencl but results for existing implementation is not optimistic because it cannot perform
10000000
iterations to use on each pixel to determine its set membership of mandelbrot fractal. I was waiting a day but it still calculate pixels. 1000000 iterations works very fast ~8sec to create 768x786 fractal.
