Same string means you didn't supply VECTORS2 instead of VECTORS, right?

This is the string I used with your kernel to get barely 405 Mhs with Phoenix 1.7:
phoenix.exe -u http://***:***@btcguild.com:8332/ -k phatk DEVICE=0 VECTORS2 FASTLOOP=false AGGRESSION=7 WORKSIZE=64 -a 1000

And this is the string which makes me 455 Mhs with Phoenix 1.7:
phoenix.exe -u http://***:***@btcguild.com:8332/ -k phatk2 DEVICE=0 VECTORS FASTLOOP=false AGGRESSION=7 WORKSIZE=256 -a 1000

Thanks for sharing, on my machine phatk2 is slower with 6950 (VLIW4) and 6550D (VLIW5 - Fusion APU).
You have 11.6 as driver!? And I said this kernel is for SDK / Runtime 2.6, which means it's best for 11.12 / 12.1 preview and newer!

Should restore some of the speed loss for 58XX owners, who switched to SDK / runtime 2.6 and is the best for 69XX owners, too.
Dia

Thanks, but no thanks. It makes about 405 Mhs on my 5870@965/300, against 456 Mhs with phatk2 on Phoenix 1.7, same string. Ati Driver 11.6.

Thanks for the work!

I can't get the file from mediafire, I keep getting an error that says something about no servers available with the file on them... Any possibility to upload to an alternative place?

Thanks in advance.

Tell me which filehoster works for you and I can upload it there. But it should be possible to upload without registering!

Dia

Just checked again and it worked, they must have been updating some servers or whatever, sorry to bother you. Thanks again, will send a donation as soon as the client is done downloading the blocks.

Great work mate !!!

So this should be pretty ideal for 5870 cards right ? What is the best setup for owners of 5870s right now in terms of SDK version, kernel, miner etc. ( software ) ? Thanks !

Well I sold my 5830, so I could only test on 6950, but what I saw there was a boost with Phoenix 1.7 in comparison to CGMINER, which uses Phatk 2.X (which seems somewhat broken with SDK 2.6). If this is not the case for your setup don't blame me Cheesy

Edit: Guys, try a setting of 64 for the WORKSIZE, it showed good results for me, but still depends on the card!

Hi Diapolo,

do you think we can still have such big improvements like in the past ?

Perhaps with AMDs Graphics Core Next architecture and new kernels or the use of new OpenCL features, but I'm not able to write a new kernel from scratch Wink

.
My current work is only to reorder some instructions in the kernel for better performance ... no big deal Cheesy

So whats the latest kernel? 8-27? Or is there a secret newer version that I'm not seeing? Because according to main page, there is an unreleased kernel thats faster than 8-27 which is also called current. Where can I get the current kernel?

It's not released, because I had no time over Christmas Wink

... I guess I can put it on later today or tomorror.

For 6950 and cgminer I have identical hashrate. But memclock is set to 690. Catalyst 11.9

Could you give Phoenix 1.7 with my latest posted version on posting 1 a try and report back

?

Thanks,
Dia

Btw.: Is anyone able to help me getting 3-component vectors to work? The kernel should be valid but in __init__.py line 50

Code:

self.size = (nonceRange.size / rateDivisor) / self.iterations

it seems that

Code:

nonceRange.size / rateDivisor

(rateDivisor == 3 if VECTORS3 is used as kernel argument instead of VECTORS2) generates a problem, because nonceRange.size is a multiple of 256, which is not dividable by 3.

I made a few quick performance checks on a 6950 + a 6650D (APU) and it's weird. CGMINER is quite a bit slower with phatk2, compared to Phoenix 1.7 with my latest kernel on my rig.

For the 6950 CGMINER 2.0.8 is @ 330 MH/s with

Code:

-I 8 -d 0 -v 2 -w 128 --auto-gpu --gpu-fan 25-50 --gpu-engine 800 --gpu-memclock 1250 --temp-target 70

.
For the 6950 Phoenix 1.7 is @ 355 MH/s with

Code:

-a 50 -k phatk AGGRESSION=12 DEVICE=0 FASTLOOP=false VECTORS2 WORKSIZE=128

.

Am I missing something? Both run with 800 / 1250 and 2-component Vectors + Worksize of 128. I'm using SDK 2.6 installed with Cat 12.1 Preview!

Someone interested in keeping that kernel up with 2.6? 3-component vectors are working now and it would need to get reordered a bit again to get better ALUPacking as the compiler backend has apparently changed in a way. I lost my interest in bitcoin, but it would be an interesting experiment. I believe pre-2.6 speeds can easily be regained.

Anyone know of a decompiler I can use to look at the compiled source? It'll help me remove unnecessary variables and the like. Granted, I'm only decent with assembly at the moment, but I wouldn't mind seeing the finished product when the optimizer takes hold.

Take a look at AMD APP KernelAnalyzer 1.9 it creates assembly like output for OpenCL kernels and gives register informations and that stuff ... it's in the AMD APP SDK.
