It depends ;). The new version is already running in our OpenCL driver, 
which means that it is more or less at the same level of the old 
implementation now. However, the exploitation of the divergence analysis 
as described in our CC'12 paper is not fully implemented yet, I can't 
seem to find the time for that right now :(.
Anyway, if you guys are interested, I can give you access to the repository.

Best,
Ralf

I think that would be useful, thanks!
