Hi,

I don't think so. In WebKit we did some OpenCL optimizations, but I am not sure the general concept of a backtracking, NFA based engine is suitable for OpenCL. At least the whole engine is surely way too big. Perhaps something like the JIT compiler could work, just generating C like code for OpenCL. But uploading the input could be too expensive, and searching only the first match is difficult, since I am not sure that other running kernels could be stopped when the first occurrence is found. Perhaps a DFA based engine is better for such purpose, but the first occurrence issues are still similar. OpenCL is a powerful tool, but I am not sure this is an ideal use case for it.

Regards,
Zoltan
