How to evaluate Altera's openCL support?

I filled a doc request to have this information enhanced since it's not readily available as far as I can tell as well. OpenCL has it's own feature line so it uses the same license management scheme as Quartus but it's a separate license. I think when OpenCL licenses are cut they come with the necessary Quartus II license as well since it's a prerequist but I'm not sure what happens if you already have a Quartus II license (I'm guessing you'll just end up with two Quartus II feature lines in that case). I'm not overly familiar with the procedure to get an OpenCL license but I would chat with your Altera sales rep to see if something can be worked out.
