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 Tongue

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?

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

Have fun!

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.

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

Looks great and working nicely.

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

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 Cheesy

+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.

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

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.

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

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.

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?

yes, but it gave same error

Quote

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 Tongue

Me neither

Anyway, thanks for helping me.

works great in win7 32bit
better than phoenix

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

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. Wink

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

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?

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:[email protected]:8332

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

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! Grin

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