[Oisf-devel] Earlier work on CUDA GPU Acceleration

Not sure if you guys have seen this or not, but I just ran across these two
papers detailing an experimental implementation of CUDA GPU acceleration for
Snort using a port of the well-known Aho-Corasick algorithm. According to
the researchers, with this setup they were able to achieve substantial
pattern-matching performance improvements, in some cases up to 48x the
throughput possible using the normal CPU implementation (and this was on
older GeForce 9000-series hardware).

I'm passing these links along in case the work done by these folks might be
useful in developing Suricata's GPU acceleration capabilities.
