Hi,

I offer my rapidshare account for the links. I would mark the files as trafficshare, meaning no popups, no wait time, nothing. Just like a normal download from, lets say any software website, click and go. You wouldn't even have to go to the rapidshare page.

And since we're talking about 4KB, I couldn't care less Wink

Try it:

Version 2011-07-17: https://www.rapidshare.com/files/4111719732/2011-07-17_kernel.7z

Can somebody upload a version of the kernel we can extract natively in windows without downloading yet another compression/decompression app?

TIA

edit:  Online decompression:  wobzip.org

The kernel is that small I guess it wouldn't even need to be zipped. Download volume should not be that big.
But I really like 7-Zip, it's free and open source ... you should consider to install it as your default packer Smiley.

Seriously just get 7-zip and remove the rest, its free, open source and its default format .7z is probably the most effective lossless compression format commonly used.

i tried it on one of my 3 x 6990 mining rig - normally using poclbm with the phatk per GPU 408 MH/s - with your kernel per GPU 407 MH/s

Too bad, but thanks for trying Smiley. Perhaps a new version will be ready by the end of this week. But guys don´t expect a huge improvement. On my setup I get 0,5 - 1,5 MHash/s more than with 2011-07-03 kernel version (guess the puzzle reaches it's end ^^). I can´t work like I would like to because the AMD APP KernelAnalyzer doesn't work ... hoping for a new version!

This isn't exactly a fair comparison since phatk was specifically targeted at VLIW5 GPUs on SDK 2.4. A better comparison would be against phatk without this modification.

The newest kernel gives an error on only 1 of my 4 cards. Phoenix says something about a kernel or OpenCL error and suggest that the card might be malfunctioning (and then keeps mining), and poclbm just crashes. The card is a ASUS 5870, but I have an identical model that works fine. The error might not happen for like 20 minutes. And the card apparently works perfectly since various pools accept the results from that card with no special extra-stales.

Also, I find it weird that the newest kernel seems to add some Watts of power consumption (I need to measure this propperly though).. Since its doing less operations and that way achieving a higher rate, shouldnt it consume the same?

Bumped my hash rate from about 428 to 431 (3 MHash/s or 0.0696%), although previously I was using a customized kernel that has some of the same changes you've made so this increase is not representative.

Edit: XFX 5870 @ 950/315

4x 5870 @ 960Mhz Core = rock solid 1748Mhash/s

After I put the modified kernel:

Variable 1746-1751 with most of the time staying around 1748

So no use for me, but thanks for your effort anyway Smiley

I get 5MH/s increase on 5850 (372MH/s -> 377MH/s) and 2MH/s increase on 5770 (215MH/s -> 217MH/s)

hmm, it does seem to vary a hell of a lot more though

Since most gpu miners are using now the phatk kernel you should upgrade to 2.4. Phatk kernel is optimized for 2.4. You will get better results.

Well, you may get better results.  For me:

SDK 2.4:  393.7 -> 396.8
SDK 2.1:  399.4 -> 399.4

That's for a Sapphire HD5850 Xtreme 970/300@1.0875V using catalyst 11.6 on Linux and phatk
VECTORS BFI_INT FASTLOOP=false AGGRESSION=14 WORKSIZE=256

Definitely try out both SDK 2.1 and SDK 2.4 though.  If you are using Windows there's also an early version of SDK 2.5 with catalyst 11.7 which may be worth a look.

New version is ready, DL here: http://www.mediafire.com/?f8b8q3w5u5p0ln0

Updated first post with changelog and performance info. This one should be a bit faster on 69XX cards than the original phatk, faster than all other phatk versions I did on 58XX and faster on non BFI_INT cards because of a change user 1MLyg5WVFSMifFjkrZiyGW2nw suggested!

Try, have fun, comment and donate Cheesy.

Thanks,
Dia

from ~402Mh/s ---to--- ~405Mh/s   Shocked and I have 4x5850 sapphires each clocked to 1000Mhz.


Will take time to see what stales rate will be. With the last kernel it was around 2-3 %. Usually closer to 2%.


PLEASE KEEP THESE COMING  Grin
