Using poclbm With The phatk Kernel

[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.

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.

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 

works great in win7 32bit
better than phoenix

send you 0.1

Thank you, wahbasah. That is very much appreciated. I hope it helps you make more Bitcoins

yes, but it gave same error

Me neither

Anyway, thanks for helping me.

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

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.

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.

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  

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

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.

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!

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. 

I never had a problem with phoenix locking up...
Every how much time it should happen?

any chance for a windows binaries ?

[zimpixa]

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)

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?

Something isnt right

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.
