Bumping an ancient thread. Just noting that phatk 2.2 still holds the crown for fastest kernel on 2.1, 2.5, and 2.6 SDKs for VLIW5 tech (radeon 5xxx and 60xx-68xx). I hope phateus can come back and do even moar tweaks for moar speed!

I'm checking back in after being gone for so long...  I just downloaded the 2.6 SDK and it destroys my optimization...  Undecided I will see if there is anything I can do without completely rewriting.  Stay tuned and I should have more info later this week.

P.S. Thanks to everyone who has donated to me in the past, I have been busy lately, but I have not forgotten.

Should be noted that current phatk 2.2 still runs amazingly fast on 2.1 SDK; people suggested poclbm but phatk2 still runs fastest for my system with 2.1 along with 2.4/2.5. At least it does for me. I use VLIW5 hardware. Perhaps keep a 2.1-2.5 kernel around for those that want to keep using it, and a seperate 2.6 optimized kernel for those that need it for GCN architecture hardware or people that game with their gpus (they'll probably be running 1GHz+ on memory which is better suited for VECTORS4 which works well with high memory frequency)
