Hi XXXX,
The GPU assist is still not available, due to a legal IP dispute, we can't provide more information than this at the moment, but we wouldn't offer this if we didn't think we could deliver the promised software. At the moment there are standalone bitstreams for acorns available to provide some use, with more standalone algorithms coming as they're developed.
You can find it here: https://thefpgaforum.com/forums/bitstreams.16/
Thanks

I just re-sent them a mail to check things go on.
