Using poclbm With The phatk Kernel

[fpgaminer]

I have had a lot of trouble with phoenix. The biggest issue being that it oftens gets stuck on "[0 Khash/sec] blah blah" and never reconnects to the server. This is especially bad when I have torrents running, even when I limit torrent traffic. The only reason I put up with it is because phoenix supports the phatk kernel, which gets me an extra 20MH/s per card.

Well, I got tired of it, so I forked poclbm and hacked it to support phatk. Here's my fork:

https://github.com/progranism/poclbm

So far so good, poclbm is happily running without any issues whereas my phoenix instances are freezing up  MH/s is about the same. 339 MH/s instead of the 340 MH/s I get on phoenix. Close enough.

Lemme know if this helps anyone else.

Thanks so much, I have the very same issue with phoenix getting stuck and making me lose hours of mining (even running several copies for each gpu is not enough since all one of them can hang if left running long enough).

I'm going to test this right now.

[fpgaminer]

Let me know if it works okay. I've been running it since I posted and so far none of the instances have failed. However I haven't measured stale share ratio yet; I was getting 0.1% with the old version of phoenix I had which was very nice.

[fsasa70]

Super noobie question here...

How do I make this work? Do I just drag and drop to the poclbm folder?

Because am seeing no difference when I drag and drop the phatk files...

[huayra.agera]

This is interesting and yeah, how do we make this work? A simple guide maybe? Thanks!

Sadly it causes a kernel trap after a few minutes of work, I'm using it onto a LinuxCoin pc with two 5850s which has been working ok with phoenix (apart from the hang problem) for more than three weeks.

And when it traps I have to power-cycle the pc. 

best regards.

[Sukrim]

I'm already thinking of killing + restarting phoenix every 10 minutes... would loose me less time than it already has with these lockups!

[gentakin]

Works great for me. I actually had the same idea a few days ago, but was too lazy to actually look into it.
Hashrate is about the same. (Maybe only 283mhash/s instead of 284mhash/s.)

It's also possible to clone fpgaminer's poclbm-phatk git repo, then merge luke-jr's branch for better console output into it. There's 1 conflict that can easily be solved by using luke-jr's version of the code.
edit: What I actually wanted to say is: "[..]merge luke-jr's branch for better connectivity issues handling into it.". Sure, it has better console output, but that was not the reason why I merged his branch. Link is here: http://forum.bitcoin.org/index.php?topic=19051.0

Thanks!!

[fpgaminer]

Works great for me.

Yay!

It's also possible to clone fpgaminer's poclbm-phatk git repo, then merge luke-jr's branch for better console output into it.

Thank you for checking that! I was going to look into luke-jr's branch as well, so I could get a good figure on the # of stales I'm getting. Since you've confirmed the merge is simple, I'll try doing that soon.

Sadly it causes a kernel trap after a few minutes of work, I'm using it onto a LinuxCoin pc with two 5850s which has been working ok with phoenix (apart from the hang problem) for more than three weeks.

Woah, weird. Have you ever run poclbm on that machine before?

This is interesting and yeah, how do we make this work? A simple guide maybe? Thanks!

Linux or Windows?

On Linux you just:

Code:

git clone git://github.com/progranism/poclbm fpgaminer-poclbm

And then use it like a regular version of poclbm.

For Windows ... well ... I'd have to get PyOpenCL and stuff up and running and see if I can package something together.

[fpgaminer]

Merged in Luke-Jr's work on poclbm. I put it on a different branch in my fork: https://github.com/progranism/poclbm/tree/with-luke-jr-mods

Seems to work just great 

[wahbasah]

+1 for win version

[fsasa70]

+1 for win version

Me too 

[Internet151]

Windows version please!

[fpgaminer]

Alright, here's a stab in the dark for the Windows version:

Binary: http://www.bitcoin-mining.com/poclbm-with-phatk-lukejr-win32-20110620a.zip

Source: http://www.bitcoin-mining.com/poclbm-with-phatk-lukejr-src-20110620a.zip

The source archive includes the code, and a folder called "win32" which is what I used to build the EXE from using py2exe, in case you want to do it yourself or use the python code directly.

Please note: This worked on my Windows 7 64-bit machine, but I only have an nVidia on here so I couldn't do a full test. I also don't have a "clean" Windows machine without Python and other installed dependencies on it, so I don't know if the above zip has all the dependencies packed in. Just let me know if it doesn't work

[c_k]

Ah, with Python 2.7 this looks better than Python 3.2 however it also seems to need the PyOpenCL module to run

[huayra.agera]

Hi! I have it now up and running in windows7x64 (I downloaded the binary) and I have about the same hashrate on my 5850 (381 with Phoenix+phatk)960/300/1.174v. No 1 Mhash difference. Haven't had any stales yet. Will be monitoring for the next hours/days.

I hope this gets integrated to the major GUI miners/frontend. This is just great! Thank you for your work!

Hi fpgaminer,

poclbm does not work, it gives an error about access rights and I did not bother to look at it more deeply.

I've made a few more tests with your work and it always freezes or traps after a few minutes of work. The longest run has been less than half an hour.

So I decided to go back to phoenix.

Best regards.

spiccioli.

ps. I'm running a 2x5850s rig with linuxcoin 0.2a as operating system and I start two instances of poclbm, one for each gpu, inside a screen session like this:

DISPLAY=:0 ./poclbm.py -v -d 0 -a 2 --user=... --pass=... -o api.bitcoin.cz --backup=user:pass@useast.btcguild.com:8332

My 5850s are running 885/295 (core/mem) at 1.08V and produce around 350Mh each.

[Dominic Sayers]

Working fine in Windows 7 64-bit. I'm getting about the same hash rate, but enjoying luke-jr's improved status messages nonetheless.

[huayra.agera]

Hi guys! fpgaminer's fork is working with lvlrdka22's frontend as a compliment. You might try it. Works well, too. This is for windows.

Did you chmod +x poclbm.py?

Either way, sounds like your setup doesn't like poclbm for some reason. I can't think of anything else to try. I normally don't develop GPU miners

Awesome, thanks, i don't know if I have python installed... this build works about the same speed as guiminer - the new stats from Luke-Jr are pretty neat.

[Nythain]

This thread needs a bright shiny gold star. Thanks for this. Working fine for me, Windows 7 64bit.

[SlipperySlope]

I'm running poclbm with a hash rate of 202 MH/sec per overclocked 5770.  Can I expect better with phatk?

When I tried phoenix my rigs had higher CPU utilization and became unstable.

[Coaster]

my 6970 gets +1mhash improvement (over phoenix) using -f0 flag with your build. interesting.. but every mhash helps

[ace24]

+1 for a sticky. This is working great for me with ~same Mh (maybe 1-2% slower) as phoenix/phatk in Win7 64-bit, yet with CPU essentially at idle instead of 1 core maxed. System is noticeably quieter and I expect it uses less energy as well. Will be sending you some BTC if it proves to be stable with low reject rate.

Highly recommended for ATI users, especially in these hot months where every watt counts.

[Mobius]

Merged in Luke-Jr's work on poclbm. I put it on a different branch in my fork: https://github.com/progranism/poclbm/tree/with-luke-jr-mods

How do I implement this in Ubuntu 10.10, SDK-2.1 and Cat-11.2?

[fpgaminer]

How do I implement this in Ubuntu 10.10, SDK-2.1 and Cat-11.2?

From memory, so I may mis-type something

Code:

git clone git://github.com/progranism/poclbm fpgaminer-poclbm
cd fpgaminer-poclbm
git checkout with-luke-jr-mods
./poclbm.py

[Mobius]

Thank you so much,
I haven't coded in 20years, things have gotten easier since then.

Looks great and working nicely.

[Elanzer]

With this version over regular poclbm, my HD5830s get about 10mhash/sec more per card.

But there's just one problem, I keep getting long polling exceptions working off BTCGuild USWest such as:

Code:

23/06/2011 15:18:44, long poll exception:
Traceback (most recent call last):
  File "BitcoinMiner.pyc", line 350, in longPollThread
  File "BitcoinMiner.pyc", line 308, in request
  File "httplib.pyc", line 950, in getresponse
  File "httplib.pyc", line 390, in begin
  File "httplib.pyc", line 348, in _read_status
  File "socket.pyc", line 395, in readline
timeout: timed out

Sometimes it will reconnect and recover, sometimes it doesn't bother and just sits there idle, until I notice that the miner has been disconnected for a few hours. This doesn't happen with regular poclbm.

Hi,
fpgaminers version of merging his phatk branch with luke-jr's branch seems to miss some of luke-jr's patches, and github shows conflicts. So I gave it a shot myself and made a new version. Because patches often didn't apply, I had to merge manually. So here it is:

→ Now you can choose between the original poclbm kernel and phatk via command line (-P or --phatk)
→ It has all of luke-jr's improvements, including more detailed statistics (with some cosmetic changes by myself)
→ Some other very minor improvements

Here is the patch that is meant to be applied to fpgaminer's fpgaminer-poclbm branch.

Get his branch via

Code:

git clone git://github.com/progranism/poclbm fpgaminer-poclbm

and apply the diff with

Code:

patch -p1 <diff

Have fun!

Vista x64 - working.

Tried to insert it also to Guiminer, but some error found that cannot find module wx. Anyway, its working with AOCLPM, so not so big deal.

Works with XP x32 also, but couldnt get better results when both cards are running (they are throthling down about 10% more than on same settings, which are also best for this version,  with Guiminers poclbm)

[shakaru]

I got something odd, running on a 5830 with the following

xe --device=0 --host=http://api.bitcoin.cz --port=8332 --user=5 --pass=5 -f 0 -w 256 -a 1 -v

Oced to 1005, 300 and only getting 180-195?

Sorry, no chance for a binary (none of my computers has Windows on it), but there's also no need for binaries: Just install python and pyopencl. And, more generally speaking, never ask for binaries in a forum, especially if it's somehow related to bitcoins, you now, security and paranoia and stuff…

Hint: That magic phoenix/phatk +3% optimized line of code, that's posted at several places in this forum, also works with the phatk in fpgaminers or my version, of course. You can modify that line of code very easy if you have the code; it would be very difficult to change something in a binary.

[fpgaminer]

m0mchil released an update to the poclbm project, which includes the work from this thread and other goodies. It includes binaries:

http://forum.bitcoin.org/index.php?topic=1334.0

[Ali]

Are you sure that it does include it? I'm using it right now but the output shows only the hashrate (but not all the stuff you/luke-jr added).

[huayra.agera]

I think it doesn't have the luke-jr mod but it definitely has the phatk + 3% boost.

[techwtf]

fixed the Ma define manually, 332M -> 330M. but gained the fallback function. nice.

[spiccioli]

I think it doesn't have the luke-jr mod but it definitely has the phatk + 3% boost.

Is poclbm using phatk kernel by default now?

[huayra.agera]

I tested and yes it uses it by default.

[brunoshady]

question:




the argumments, I use the poclbm default arguments, -f -v -w etc, or I use the phoenix + phatk arguments? -worksize -aggression... etc?

back up the directory sturucture of the program/package first - in case you need to go back

for git repositories
cd to directory
git pull

for svn
cd to directory
svn up

remember - you may need to configure it again

[niooron]

@fgpaminer:
How about a new version with 3% speed boost, diapolo's kernel improvements and luke-jr's output improvements?
