Title: GPU Mining on OS X Using poclbm Post by: rethaw on June 05, 2011, 07:02:15 PM Mac users are reporting difficulties with the latest kernels. If possible, make a copy of your miner before updating to a newer version.
For those wanting to use poclbm to do GPU mining on Snow Leopard these are the steps I followed. 1) Install XCode (https://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/wa/getSoftware?bundleID=20792), its free from Apple. If you haven't already you will need to sign up for a developer account, which is also free. 2) Install bitcoin from http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.21/bitcoin-0.3.21-macosx.zip/download (http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.3.21/bitcoin-0.3.21-macosx.zip/download) (or latest). 3) Open a terminal and enter the commands: Code: svn checkout http://svn.json-rpc.org/trunk/python-jsonrpc There will now be a poclbm folder in your Applications. You can now either start solo or pool mining. Solo mining, first edit your bitcoin.conf to allow local RPC: Code: echo "rpcuser=username" > ~/Library/Application\ Support/Bitcoin/bitcoin.conf Then each time you want to start mining: Code: /Applications/Bitcoin.app/Contents/MacOS/bitcoin -server & Pooled mining: I suggest joining Deepbit (http://deepbit.net) or mining.bitcoin.cz (http://mining.bitcoin.cz). You can then start mining by entering: Code: python /Applications/poclbm/poclbm.py http://username:password@api.bitcoin.cz:8332 -d 0 Happy mining! I'm curious how many Mhash/s people with the new iMac's are getting. On my 2010 iMac I'm getting around 30Mhash/s. Note: Your device may be at a different location. You can enumerate the devices by running poclbm without any flags. Thanks to Easy Ubuntu python OpenCL mining setup (http://forum.bitcoin.org/?topic=2636) Title: Re: GPU Mining on OS X Using poclbm Post by: URSAY on June 05, 2011, 11:37:44 PM Anyone else using this?

Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 06, 2011, 02:44:01 PM Something which seems to be missing in the instructions...
I'm got the following: python: can't open file '/Applications/poclbm/poclbm.py': [Errno 2] No such file or directory I copied poclbm.py, along with a bunch of other stuff, which ended up in ~/pyopencl-2011.1beta3/ into /Applications/poclbm/ and that seems to have taken care of the error. Is there a missing line in the instructions?

Title: Re: GPU Mining on OS X Using poclbm Post by: rb2k on June 06, 2011, 02:44:07 PM Happy mining! I'm curious how many Mhash/s people with the new iMac's are getting.

Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 06, 2011, 02:54:58 PM Okay, I still haven't got this working. Now I'm getting:

Title: Re: GPU Mining on OS X Using poclbm Post by: cuthbert on June 06, 2011, 04:38:14 PM Im getting ~96 Mhash/s on my new 2011 iMac (with a ATI 6970m GPU), using the Diablo GUI published in another thread here. Kind of disappointing low hash rate I think.
Is there reason to believe poclbm would give a higher hash rate? Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 06, 2011, 04:45:06 PM Thanks afingal I added it.

I tried that and I'm still getting the same error. Make install is saying stuff like the following (pulling out select lines): pyopencl 2011.1beta3 is already the active version in easy-install.pth decorator 3.3.1 is already the active version in easy-install.pth py 1.4.3 is already the active version in easy-install.pth pytools 2011.3 is already the active version in easy-install.pth Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 06, 2011, 04:53:02 PM The difference between Diablo and poclbm is that Diablo runs on Java and poclbm on Java. Some people have noticed appreciable differences between the two, though with the right flags they should be very close to each other.
I am now using poclbm because it can do regular CPU mining as well as GPU, even though its only a few more Mhash/s. It also shows the hashes of each share. There's no risk in seeing if there is a difference for you. Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 06, 2011, 05:02:14 PM Im getting ~96 Mhash/s on my new 2011 iMac (with a ATI 6970m GPU), using the Diablo GUI published in another thread here. Kind of disappointing low hash rate I think. Is there reason to believe poclbm would give a higher hash rate? I arrived here by looking up and down the reported performance at https://en.bitcoin.it/wiki/Mining_hardware_comparison and looking for people who had specifically reported that they were using a Mac. poclbm gives slightly better performance than Diablo GUI in the one equal comparison on a Mac, though it's not the specific graphics card which I have. I mainly chose to try and work with poclbm because it seems to be relatively popular. I should try Diablo as well when I get a chance. It seems to me, glancing up and down the list, that Mac performance is relatively poor in general. I don't know why. It could be configuration issues or it could be a poor complier/interpreter. I don't know the specifics of the individual cases and this can be a complex thing to figure out because, even if the interpreter for a language like Python is good, it may be calling a module, somewhere down the line, written in some other language where the compiler isn't so great. Title: Re: GPU Mining on OS X Using poclbm Post by: Planetexpress on June 06, 2011, 06:06:42 PM hmm my xcode ist the latest one, we use it for development without any problems.
Could you please reposte the new code for the installation? Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 06, 2011, 06:36:21 PM Thanks afingal I added it.

I Googled around a bit, still trying to solve the problem on my own, and found the following: http://lists.tiker.net/pipermail/pyopencl/2011-April/000612.html This seems like a good possibility since I am indeed using a Mac Pro. I fumbled around trying things but I think the following are the relevant lines: Code: VERSIONER_PYTHON_PREFER_32_BIT=yes # for 32b I get the same errors as above. I'm guessing that I need to do some kind of sudo make uninstall command but I'm not sure what. Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 07, 2011, 01:01:08 AM afingal: I'm sorry you're having problems. I don't have a Mac Pro, but it does seem like it could be an issue with 32 vs. 64-bit. You can try "make clean".
Good luck. planetexpress: What is the output when you enter "/usr/bin/make" into a terminal? Title: Re: GPU Mining on OS X Using poclbm Post by: taykaypee on June 07, 2011, 11:24:34 PM Am i entering anything specific for -u username and --pass password?

Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 08, 2011, 12:14:20 AM Are you doing solo mining? If so you will use the username and password in your bitcoin.conf. If you had copied and pasted my directions verbatim these would just be "username" and "password".
For pooled mining you would use the login info you set up with your pool. Let me know how it goes. Title: Re: GPU Mining on OS X Using poclbm Post by: taykaypee on June 08, 2011, 12:20:31 AM I search for Bitcoin.conf on my computer and don't get results. Is this file on my computer?

I already tried "make clean" but I haven't tried actually booting into full 64-bit mode, which was another suggestion on the page I referenced earlier. I'll might try that when I get a chance. Meanwhile, I now have poclbm working on my MacBook although that's no where near as good as I expect the Mac Pro to be. I'll post more about that in just a bit. Title: Re: GPU Mining on OS X Using poclbm Post by: afingal on June 08, 2011, 12:53:30 AM Those are two separate commands right? Sorry I'm new to this... Yes.

Apparently the https://github.com/.... links redirect to https://raw.github.com/..... so I modified the curl commands accordingly. Now I have real stuff in all 4 files under /Applications/poclbm When I run the first command: /Applications/Bitcoin.app/Contents/MacOS/bitcoin -server & the Bitcoin application starts up and I can see the application running in another window. Seems OK. When I run the second command in the terminal window: python /Applications/poclbm/poclbm.py -u xxxxxx --pass yyyyy -d 0 I get the following line: Bitcoin is not connected! The terminal prompt does not return, and the Activity Monitor shows no significant process is running in the background. Now what? Title: Re: GPU Mining on OS X Using poclbm Post by: enewhuis on June 08, 2011, 06:37:40 PM I saw that on my setup too. I think the bitcoin.conf file settings aren't correct.
When mine contains only "rpcuser=password" the Bitcoin client works but I cannot connect my local python miner. When I supply some other rpcuser and rpcpassword I can connect but Bitcoin client won't find any peers. When I run the second command in the terminal window: python /Applications/poclbm/poclbm.py -u xxxxxx --pass yyyyy -d 0 I get the following line: Bitcoin is not connected! The terminal prompt does not return, and the Activity Monitor shows no significant process is running in the background. Now what? Title: Re: GPU Mining on OS X Using poclbm Post by: enewhuis on June 08, 2011, 07:02:21 PM I got it to work but putting these three values in my bitcoin.conf.
server=1 rpcuser=enewhuis rpcpassword=drummerz I then started the Bitcoin client and ran e-2:poclbm en$ python /Applications/poclbm/poclbm.py -u enewhuis --pass drummerz -d 0 3736 khash/s Dismal 3.7 Mhash/s tho, but this is a mere MacBook Pro. Title: Re: GPU Mining on OS X Using poclbm Post by: woodguy00 on June 08, 2011, 07:29:58 PM Thanks for the reply.
I tried the changes you made to the bitcoin.conf -- only those 3 lines (but with my username and password, of course) Still getting the "Bitcoin is not connected!" message. Hmmmm.... Running a Mac Pro 2.66GHz Quad-Core Xeon, OSX 10.6.7. Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 09, 2011, 04:16:28 AM Thanks, I fixed the error, I had put rpcuser twice in the original post and github does seem to redirect to a subdomain.
If you are having trouble getting Bitcoin connected to other nodes I suggest checking out https://en.bitcoin.it/wiki/Fallback_Nodes (https://en.bitcoin.it/wiki/Fallback_Nodes). You can add a fallback node by entering: Code: echo "addnode=69.164.218.197" > ~/Library/Application\ Support/Bitcoin/bitcoin.conf Check out the link for other Fallback Nodes. That being said it may be an issue with your firewall blocking either the bitcoin or irc ports. I strongly suggest giving pooled mining a try though. The variance on payback is greatly reduced. The one I use is http://mining.bitcoin.cz (http://mining.bitcoin.cz). Once you have set up a worker you enter: Code: python /Applications/poclbm/poclbm.py -u xxxx --pass xxxx -d 0 -o mining.bitcoin.cz Title: Re: GPU Mining on OS X Using poclbm Post by: HongPong on June 09, 2011, 04:39:16 AM After I got around those old curl urls, this worked like a charm! ATI Radeon HD5770 on old Mac Pro chuggin away at around 100Mhash/sec. The GPU is about 20x faster than the CPU! Works perfectly, huge hat tip! 8)

Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 09, 2011, 07:16:27 PM I got everything working, and I'm only pulling in 2800kH/s on my mid-2009 MBP. Is that to be expected with the GeForce 9600M GT inside it? The nvidia cards are apparently optimized for floating point calculations, while the Radeon's are optimized for integer. The hashing algorithm relies heavily on integer calculations so the AMD/ATI cards seem to have nvidia beat for bitcoin mining. You could post your results to https://en.bitcoin.it/wiki/Mining_hardware_comparison (https://en.bitcoin.it/wiki/Mining_hardware_comparison) as there aren't any results for your video card yet. It looks like the closest thing is another MBP listed on there with a 9400M at 1.9 MHash/s.

Running a Mac Pro 2.66GHz Quad-Core Xeon, OSX 10.6.7. OK -- it took several things to get running. First, when I originally installed and launched Bitcoin it did not open connections and download blocks.

Nice, can you compare the rate to what your processor gets? You can do this in poclbm using the "-d x" flag, where x is the number assigned to that device.

Most interesting -- when I use the "-d 1" option (which I presume is the processor) I'm getting about 5000 khash/sec. The Activity Monitor show all 4 CPUs are doing their thing. Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 09, 2011, 08:01:45 PM if you run poclbm without any flags it will enumerate the devices. That would be your processor. In general this is not an effective way of mining coins, but you can run one instance for the processor and another for the GPU.
Title: Re: GPU Mining on OS X Using poclbm Post by: HongPong on June 09, 2011, 10:36:21 PM Awesome, are you doing pooled or solo? I jumped onto Deepbit and get about .001 or .002 per block roughly. Not too shabby compared to the idleness of the card normally :)I am wondering if I can get my other graphics card to run this, it is older. It's a GeForce 7300 or 6300 (don't have it in front of me right now :) Also what is the best way to run something on the OSX CPU? The CPU is jelly right now that the GPU gets all the action. It would only get 1/20th the hashes of the GPU but I would like to try running it in a quieter pool than deepbit and see what happens. Title: Re: GPU Mining on OS X Using poclbm Post by: HongPong on June 09, 2011, 10:38:16 PM if you run poclbm without any flags it will enumerate the devices. That would be your processor.

Ah so just to be clear, i can open two terminal windows and run one command on the GPU and one on the CPU? Can i tell a third instance to use the second graphics card? Title: Re: GPU Mining on OS X Using poclbm Post by: HongPong on June 09, 2011, 10:41:20 PM Could you explain how the -d device flag works?

I wonder also if in this kind of box the PCIe lane settings (a weird OSX setting most people haven't seen i bet) could be fiddled with to increase throughput. EDIT - it appears the 7300 GT does not support CUDA which seems to preclude using it for this. Is there any way to run a GPU which is not compatible with CUDA? Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on June 09, 2011, 11:32:11 PM Unfortunately only 8xxx or newer cards are supported as far as I know. This has nothing to do with poclbm, just not a feature in earlier cards.

(http://forum.bitcoin.org/index.php?topic=8994.0) 8) Thanks MacCompiler. Fortunately you don't have to use XCode for anything, its just a little more straightforward then asking individuals to install a compiler. Since poclbm is in python you are only really compiling dependencies. Mac OS X actually comes with more of the dependencies preinstalled than any other system I know of (numpy, OpenCL drivers).

Title: Re: GPU Mining on OS X Using poclbm Post by: theowalpott on July 11, 2011, 12:36:42 PM Has anyone got any decent performance out of a Mac Pro using poclbm?!? I've got access to one with a 5870 in it, but the best I can get out of it is around 210MH/s - not great!
I've tried running it using the latest version from the git repo, but when I turn vectors on it gets a much lower hashrate, using anything other than the maximum worksize (-w256) seems to cause it to slow down too! It seems to get segfaults all over the place if I don't choose the options very carefully too! I've ended up using an older version of poclbm, which doesnt use the phatk kernel. Anyone got any tips? btw, this is running a 64-bit version of OS X, 10.6.8. I'm not much of a Mac guy, but I know my way round a linux/unix command line, so I've basically been treating it like a linux box. Cheers for any help :) Title: Re: GPU Mining on OS X Using poclbm Post by: robin1979 on July 11, 2011, 01:40:24 PM Has anyone got any decent performance out of a Mac Pro using poclbm?!?

Cheers for any help :) 210MH/s sounds pretty decent for a 5870 under Snow Leopard. I never got it past 180MH/s. Now running Lion (GM), I'm getting a little over 300 (310-320), with the original poclbm kernel. Could not get the phatk kernel to run with Lion, does weird things and does not submit shares (or very irregular), while it reports speeds over over 1 Thash. I did not have time to debug it yet. Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on July 11, 2011, 03:37:30 PM Hmm sounds like phatk doesn't play nicely. It may be time to branch a mac version.

Yes, I had the stupidly high hashrate issue with phatk too.. if you let it go for a minute or so, it'll produce a share and then crash out - usually spewing a lot of "verification error" type messages. I went back to the original poclbm kernel, and also made the edit to the Ma define line, which is probably why I got the extra speed. I'll have to look into getting Lion running on it once its released. It's not my machine though - belongs to my father, who has absolutely no idea what power he has inside it.. sigh. If I had my way, it'd be running linux (and windows for games)! For now though, I've set it to run in the background between 6am and 6pm (they have solar power!) every day - I couldn't even tell it was running as long as the frames were set right (went for -f120). Can't really complain about the extra 200 MH/s for free! :) Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on July 11, 2011, 04:19:44 PM Has anyone got any decent performance out of a Mac Pro using poclbm?!?

Cheers for any help :) This is more general help, but I strongly advise installing homebrew. Its like a package manager that handles building a lot of the popular linux packages. My snow leopard machine uses python 2.6, I wonder if not being on 2.7 is a problem. It can be installed easily via brew alongside the default installation.

Title: Re: GPU Mining on OS X Using poclbm Post by: pletoss on January 23, 2012, 04:28:19 PM Hi,
I packaged Kiv's poclbm guiminer into a bundled standalone Mac OS X Binary (app) using py2app and some funky voodoo patching action. No dependencies needed, just click'n'run, Apple style ;-). You can get it from here: https://github.com/downloads/pletoss/poclbm/guiminer-poclbm-macosx.dmg and give it a try. I hope this works for everybody. It's important to drag it out of the dmg to some place where it is writable before running since it needs to be able to write some log files in the app. Dragging it to Applications as usual should work. Also - join our pool ;) - btcmp.com, I added api support for balance updating and withdraw into guiminer. It's true pay per share, so no variance what so ever, you instantly get BTC's for each share you submit. We've been mining since July. If you're interested in the voodoo: https://github.com/pletoss/poclbm. Cheers, Pletoss Title: Re: GPU Mining on OS X Using poclbm Post by: rethaw on March 10, 2012, 06:38:19 AM If you're having trouble getting mining on mac I suggest using https://en.bitcoin.it/wiki/DiabloMiner (https://en.bitcoin.it/wiki/DiabloMiner) .
Title: Re: GPU Mining on OS X Using poclbm Post by: voluntaryistonly on September 17, 2013, 12:38:26 PM Hi All,
Finally got this running on my osx 10.6.8, (openpy cl was a pain to install, finally managed it, TY! to all poster's of answers & solutions ;-) currently hashing at 2.1-2.5 just a couple of questions: on the gui there is a window for "extra flags" what's that all about? (running guiminer for osx, very nice btw, very nice...) my graphics card is a geforce 9400. is there a way to tweak even more hashes out of my mac mini? would be nice if I could ;-) thanks in advance... vo |
