Okay, I took a quick look at the opencl code: - you are only invoking 255 (16x16) OpenCL kernels at the same time (max). This is not enough, not even for a budget GPU. - the code has some points to discuss (eg: why does it keep the kernel and the tesseract dat file in the local directory and not in /usr/local/share/tessdata) - Most of the issues which have openCL in it favour removing the code. - the code is deprecated, quite messy and quite slow. can we talk about this on IRC? I'm still willing to help, but it seems fairly complicated.
I will join the tesseract-orc channel on freenode. We can talk about it when we're both present.
