Modified Kernel for Phoenix 1.5

[ssateneth]

Win7 x64, 5870, Catalyst 11.7, latest GUIMiner (Phoenix 1.5).
After copying v2.0 files into "kernels\phatk" i get this messages in console:

Code:

2011-07-29 11:02:49: Listener for "itzod2": [29/07/2011 11:02:49] [4.19 Ghash/sec] [0 Accepted] [0 Rejected] [RPC (+LP)]

Here's miner starting parameters:

Code:

Your v1.0 and Diapolo's 2011-07-17 kernel works fine.

This is exactly what happens to mine too. guiminer 7-01-2011 with phoenix 1.5, using newest kernel in this thread, catalyst 11.7, win7 x64.
It just spams "Warning: work queue empty, miner is idle" in console.
I'm going to assume this kernel is either meant for an older miner, or its just plain broken. I'll be looking at this thread and diapolo's for an update. 12alu improvement is huge , might be able to break 470 mhash on my 5870.

edit: I thought you had to declare kernel arguments -after- the -k switch and argument after to declare what kernel to use.

this is an old bug of phoenix that the author was not able to fix.  Try search for idle bug.  It is not the problem of this kernel.

What makes you so sure its phoenix and not the kernel? 7-11 kernel and 7-17 kernel = work perfectly. Swap out to 2.0 kernel, spams idle.

Btw I searched that thread you linked and didn't see any mention of idle bug. :/

edit: did some other searching and apparently someone mentione didle bug was fixed in 1.50 but guiminer v2011-07-01 uses phoenix 1.50 according to my console, so I don't know where to go from here.
If someone can figure out the problem and give steps to solve the idle bug with guiminer v2011-07-01, catalyst 11.7, opencl driver 2.5, win7 x64, and this kernel, i'll donate 0.25 btc to you. I would prefer to keep using phoenix in guiminer.

Seems it only gives problem to those using GUIminer. I am using AOCLBF 1.75 & i so far didn't get any error, except strange Mhash/s variation which i already posted in this thread some posts back.
GUIminer users , try with AOCLBF to check that also gives you problem.

[Diapolo]

Yup the new kernel doesnt work.

BAH!.. I'll look through it, tonight I am going to a Sublime with Rome and 311 concert... so this weekend.

 

1st question, how is 0x2004000U in line 170 computed? Currently I don't get it .

Dia

Basically, since only the last bit is different between the 2 nonces W3.x and W3.y, the first calculation done on those values is P2:

Code:

P2(18) = rot(W[3],25)^rot(W[3],14)^((W[3])>>3U);

So, basically, instead of flipping Bit 0 on W[3] and calculating both W[18].x and W[18].y, we can calculate W[18].x and W[18].y will be the same besides bits 25 and 14 being flipped

Code:

P2(18).x = rot(W[3].x,25)^rot(W[3].x,14)^((W[3].x)>>3U);
W[3].y = W[3].x ^ 1, therefore:

P2(18).y = P2(18).x ^ (rot(1,25)^rot(1,14)^((1)>>3U));
so, P2(18).y = P2(18).x ^ 0x2004000U;

This is the first change that I implemented into my kernel, but it seems that only 69XX cards do benefit from that change. Will investigate further ...

I tried aoclbf about a week or 2 back. I didn't like how the on-screen display was ugly, or didn't even show, so I didn't know the status of my miners. :/

[fpgaminer]

Good stuff Phateus I'm getting an extra 2-3MH/s with your newest kernel compared to Diapolo's last kernel. I merged the code into my fork of poclbm and it seems to be working fine there (with command line option --phatk2):
https://github.com/progranism/poclbm

The only bug I found was that the kernel wouldn't compile without BITALIGN. Not really important, since all my mining cards support BITALIGN. It complained about rotate being ambiguous.

Keep up the good work!

[techwtf]

I'm also trying to port the kernel to poclbm.

Update: Is SDK 2.4 Required? I'm using 2.1.
without VECTORS, it works...

[techwtf]

Finally Working now. 435.5 -> 437.2. Some other small issue still exists, but not kernel related.

[Vince]

I had some trouble getting this to work with SDK 2.4, but finally its running.

On my HD6950 I get ~343Mhash/s,
with diapolo's 11-07-17 its slightly better, ~345Mhash/s.

I tested some combinations - but both run best with BFI_INT WORKSIZE=128 VECTORS AGGRESSION=11

[MiningBuddy]

V2 works fine on my windows box with 11.6 drivers and sdk 2.4 (gives me around 3mhs extra)
But it does not work on my linux boxes with 11.5 drivers and sdk 2.1 or 2.4, giving errors such as  FATAL kernel error: Failed to load OpenCL kernel!

Dropped back to diapolo's version on my linux box.

Thanks!

doesn't work when vectors are turned on

"[0 Khash/sec] blah blah" is referring to the idle problem.

That is with the original kernel that people are having the idling problem.  And the author basically said he will not be able to fix that bug and he is leaving it to other developers.
He claimed the idling bug might be fixed in 1.50, in fact it was not.

The idling bug has something to do with the AGGRESSION option, try lowing it might fix the problem.

Im having issue with this version 2.0 of phatk

On my ubuntu machines running phoenix 1.5, and the 3 updated files from phatk 2.0, I get some Queuereader error and it just hangs.

On my windows machines Im using phatk 2.0 with phoenix 1.5 and it isnt giving me the same error, works great(additional 9mh/s gained from previous diapolo kernel changes.)

[Diapolo]

Phat, what is the effect of "LLLL" instead of "IIII" in the .py file? It seems to work even with IIII.

Thanks,
Dia

[1bitc0inplz]

Hey,

Thanks for the updated kernel. My 5830 went from 303 MH/s to 307 MH/s.

However, this new kernel does not seem to work for my 5670, I went back to Diapolo's latest for that card. Using this kernel on my 5670 resulted in a strange "connecting" / "disconnected" loop where the card never actually did any hashing.... very odd.

I don't know if this helps you any, but I'm on Windows 7 64-bit, Catalyst 11.7, Phoenix 1.5, and the configuration that I normally use for my 5670 is:

Code:

phoenix.exe -k phatk VECTORS BFI_INT FASTLOOP=false AGGRESSION=15 WORKSIZE=128 -q 3 -u http://username:password@pool.bitp.it:8334 DEVICE=1

I tried all aggressions from 1 to 14 as well as changing FASTLOOP from false to true. Setting to true would just spam idle. Setting to false above aggression 6 would also spam idle. Setting to 6 or lower would spam stuff like..

...which I know is absolutely wrong. Plus my GPU utilization is still 0% when it's spamming that.

The donation (or prize if you want to look at it like that) of 0.25 btc for a fix to this while using guiminer v2011-07-01 win7 x64 is still up for grabs.

edit: I also tried different WORKSIZE, no avail.

Under regular phoenix (no guiminer) the kernel seems to work, though the improvement isn't as big as I had hoped. Still looking for a fix for guiminer based phoenix, unless the phoenix for guiminer is bad. I don't suppose anyone knows is subbing original phoenix 1.5 (the 6 meg one) in for the 22KB one in guiminer will work?

edit2: subbing the 6800KB phoenix.exe in guiminer dir instead of the 22KB one -seems- to work (my shares are going up) but guiminer doesn't know what phoenix is doing. it only shwos shares going up. It doesnt show hash rate or any system messages in the console (LP new block, opencl errors, etc)

[fpgaminer]

I am running SDK 2.1, it's either -v or --phatk2, doesn't work with both

How odd. Do you recall what the error message was, if any?

[Yannick]

I have two 5870 in my machine with W7 ultimate, AERO disabled.

I'm using:

SDK 2.1
ATI Drivers 10.7

I tested all drivers and SDK versions, this combination of driver and SDK version gave me the highest Hash/sec.

But I'm not able to use the phatk kernel. I'm getting the following error: FATAL kernel error: Failed to load OpenCL kernel!

How can I fix this? poclbm works fine. I'd like to try phatk too.

[macboy80]

Working well for me.

Radeon 6950 @ 900/900
7/11 = ~360 Mh/s
2.0   = ~370 Mh/s

Windows 7 x64 AERO
Phoenix 1.5 -k phatk DEVICE=0 VECTORS BFI_INT FASTLOOP WORKSIZE=128 AGGRESSION=8
Catalyst 11.7
SDK 2.4

Thanks for the hard work.  

EDIT: Did not work in Phoenix 1.4. I had to upgrade to 1.5.
