I don't find it odd that they're getting the press. Sure, RapidMind is good stuff, and really lowers the bar for parallel programming, but hand tuned programs will still be faster, just slower to develop. What I do find odd is that Elcomsoft actually applied for a patent on it. I mean, you have Lavalys who has a program called EVEREST that does "aes multi-threaded benchmark" and supports nVidia cards. And there are many others who have crypto projects on video hardware. You even have PureVideoHD by nVidia that supports AES on their own hardware! There will be plenty of prior art to void the patent. Maybe they applied for the patent simply for the publicity that it would generate? Yeah, I think that's it. Why else would they announce to the press that they have "applied for" instead of wait until they actually got it? --Curt On 10/29/07, Dave Aitel <dave () immunityinc com> wrote:
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Does anyone else find it odd that Elcomsoft is getting a lot of press for something relating to cracking on video cards, when you could just write your cracker in RapidMind and be done with the whole problem? No doubt that was one of RapidMind's early test programs. In any case, it's interesting that Linux Journal and MSDN Magazine are both focused on parallelism lately. Both of them are a bit "off" in my opinion. The answer is going to be a language that abstracts data access that extra layer to make parallelism something your compiler does for you. It's not going to be parallel additions to already non-parallel languages. You have to love the "caveats" in MSDN Magazine about using "Only one parallel loop at a time". And also "Parallel exceptions in LINQ are non-deterministic"! Imagine the hilarious security side effects from these sorts of half-backed parallel solutions. - -dave -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFHJgJjB8JNm+PA+iURAoFBAJsEKNVtzfBtXNKAgncZZ2+K8Vy1FwCgn1NF +J6SZ7idN0oYLr6E9cKQic4= =coMQ -----END PGP SIGNATURE----- _______________________________________________ Dailydave mailing list Dailydave () lists immunitysec com http://lists.immunitysec.com/mailman/listinfo/dailydave
