[Oisf-users] CUDA ERROR

[Erich Lerch]

Agreed.
We made some tests with CUDA about 2 or 3 years ago.
We didn't see any noticeable performance advantage, and had some
stability problems, too.
AFAIK the CUDA code has not evolved since then.

You'll probably be better off reading the tuning guides by Peter and
Michal, and implementing Hyperscan.
