further improved phatk_dia kernel for Phoenix + SDK 2.6 - 2012-01-13

[Diapolo]

Hey guys, I'm making good progress for 69XX users and need a few to test my current version as I want to mature it before release.

- only 69XX users / users on VLIW4 design cards
- I need Win and Linux users
- I need SDK 2.1 / SDK 2.4 and SDK 2.5 users

Drop me a PM, if you want to participate and meet the requirements, I will then send you a DL link! If you have received the files the test results may be posted here and may be freely discussed, so that's no shitty NDA or something . I only want to make sure that the kernel works and can compete with phatk 2.1 .

I'm sorry to say, but 58XX users are better with phatk 2.1 for now :-/.

Regards,
Dia

Alright diapolo, you got your work cut out for you. Phateus fixed the guiminer bug (It was in his kernel. 1 too many #'s in __init__). You do great work; you might want to join forces at this point though

No way! Competition breeds innovation.

I like to look at his code and even to share ideas. I mean Phateus uses parts of my mod for his re-work of phatk 2.1 and I WILL do the same .
So, I share Tx2000's oppinion and would like to keep our work separated ... I think this leaves more room for improvements and for competition .

New version was just released, it should be the fastest for 69XX cards:
Download version 2011-08-04 (pre-release): http://www.mediafire.com/?upwwud7kfyx7788

This is the preferred switch for Phoenix in order to achieve comparable performance:

Code:

-k phatk AGGRESSION=12 BFI_INT FASTLOOP=false VECTORS VECTORS2 WORKSIZE=256

or

Code:

-k phatk AGGRESSION=12 BFI_INT FASTLOOP=false VECTORS VECTORS2 WORKSIZE=128

Please test this version with SDK 2.4 / SDK 2.5! SDK 2.1 performance seems worse, but at least it should work. Report any errors and problems here and let me know what you think.
Have a look at your cards temperatures, I got a report, that they may be lower, which would be great .

I just tried this on my 2 6970's Cat 11.7 SDK 2.4 Win 7 x64
Using poclbm on GUIminer with your 7-11 Kernel = 425.4 -v -f0 -w 128
Using phoenix on GUIminer with your 8-4 Kernel = 425.5 -k phatk AGGRESSION=12 BFI_INT FASTLOOP=false VECTORS VECTORS2 WORKSIZE=128
Side note the phoenix miner stays better fully utilized now meaning less fluctuation it's ranging from 425.4 to 425.5 where as using poclbm I was getting ranges of 424.8 to 425.4

Keep up the great work.

How does this compare to the other one Phateus has?

[joulesbeef]

2011-08-04 (pre-release): 1368 ALU OPs (23 less compared to original phatk 1.X / Cal 11.7 profile)

is it only for 69xx?

i get a steange new error import error no module named bfipatcher

I can't give you exact numbers as I don't feel like reinstalling kernel 2.1 but I do know it was slower for me than this latest Kernel from Diapolo

[joulesbeef]

Ok found and downloaded a copy of bfipatcher.py

did you mention this dependency? was I supposed to have it already?

First run.. way way slow... oh i need vectors vectors2.. oops.

ok seems to be working.. will keep an eye on the stale count.

faster than 7-17 for me.. slower than phatk 2.1 edit... no rejects on phatk that was my pool being bad

1.50 phoenix command line

5850 920c 315m 1.1v - 11.4 preview w/ 2.4 SDK

396-397Mh/s

with the recommended WORKSIZE=256 flags.


Get 399 with phatk 2.1. I will run for awhile to see if there is any changes with stales though I was not getting many to begin with on 2.1 anyway.

the 8-4 prerelease for some reason lowered the hashrate on only 1 of 2 of my cards.. (the second card went from an average 426 to 389) same OC settings while card #1 remained around 426 (6970's)

Phoenix 1.5 has the bfipatcher.py included, so I never included it in any kernel package .
The phatk version will be faster for 58XX cards, but 69XX should be faster or even now.
Guys just figure out which version works best for your personal configuration!

Are you sure the VECTORS2 switch IS set!?

04-08-2011 version reduces hash speed on 5870.
I used vectors 4 & got only 444, while 2.1 phateus gives 447.

The current phatk should be faster for 58XX, sorry, but I said it _IS_ faster for 69XX .

Catalyst 11.6, SDK 2.4 here. Jumped from ~428 to ~435 with 5870, 950/300 clocks.

My friend got from ~416 to 425 with 920/300 clocks, also 5870 with Catalyst 11.5, SDK 2.1.

Keep up the good work, Dia!!

No problem mate, that's 10 BTC each card :-D.

I am happy to report these results for my 5830 running on SDK 2.4, fglrx-driver 1:11-6-2 (Debian unstable ~3 weeks snapshot), phoenix 1.50 and options "VECTORS VECTORS2 BFI_INT FASTLOOP=false AGGRESSION=14 WORKSIZE=256":

* 07-11 @ 1040 Mhz - 334 Mhash
* 08-04 @ 1040 Mhz - 335,7 Mhash

* 07-11 @ 1050 Mhz - 337,3 Mhash
* 08-04 @ 1050 Mhz - 338,9 Mhash

07-17 was untested because of lots of hardware errors. The even more happy news for me is that 08-14 brought the number of hardware erors at about the same level as 07-11 (~0.2% of the accepted shares).

Thank you again for your work and I'm looking forward to having this kernel ported to cgminer!

You don't need VECTORS VECTORS2. Just VECTORS2

It says otherwise in the first post
