That's awfully strange. I tried it on a quad-core CPU with hyperthreading, and got about 120Kh/s at about 400% CPU usage. I'm not sure what to tell you; one thing you can try is specifying the number of mining threads in the setgenerate command, e.g. for 4 threads. Well yeah, I did try setting the number of threads with the setgenerate command. See above. Ah, okay, I missed that the first time around. A few further tries indicates that there is some kind of bottleneck above 4 threads.
setgenerate true 1: 36Kh/s, 101% CPU (61% idle)
setgenerate true 2: 69Kh/s, 198% CPU (52% idle)
setgenerate true 3: 98Kh/s, 290% CPU (35% idle)
setgenerate true 4: 115Kh/s, 366% CPU (27% idle)
setgenerate true 5: 90Kh/s, 360% CPU (26% idle)
setgenerate true 6: 68Kh/s, 283% CPU (35% idle)
setgenerate true 7: 47Kh/s, 262% CPU (39% idle)
setgenerate true 8: 46Kh/s, 259% CPU (37% idle)
I doubt I'm running out of RAM—I have almost 9GB free with everything running right now. The only thing I can think of is that my slow 800MHz DDR2 RAM could be the bottleneck. But that seems intuitively farfetched.
If I set the Windows CPUminer to four threads (-t 4) and setgenerate true 4 I'm getting nearly 18KH/s per thread in CPUminer plus 48Kh/s in Securecoin for a total of 120Kh/s. For whatever reason I'm maxing out at 120Kh/s.
Confirmed: this is true even if I am running the Windows Securecoin client and the Mac Securecoin client concurrently.
Just for comparison's sake, on the laptop I get:
setgenerate true 1: 37KH/s, 100% CPU (63% idle)
setgenerate true 2: 54KH/s, 198% CPU (39% idle)
setgenerate true 3: 58KH/s, 270% CPU (14% idle)
setgenerate true 4: 57KH/s, 320% CPU (3% idle)
Since this machine has only two cores, this supports your assertion that the addition of hyperthreaded virtual cores does not help. (Which sort of makes sense.)
Yeah, I don't think that these hashing algorithms are particularly hyperthreadable. I'm baffled by your results on the 8-core system, though. All I can think is that the threads on each core of each CPU are contending for CPU cache, but your results in Parallels contradict that. Although I'll add this: if you're getting 120KH/s on your quad-core system, you too might be hitting a bottleneck and might be well-served by trying fewer maximum threads. Yes, that's about twice what I max out at with my dual-core system, but I'm guessing your quad-core CPU is a lot faster than my 1.8GHz i7.
Interestingly, looking at CPU stats in XRG in realtime while I'm running the wallet's miner shows my main cores maxing out, but the hyperthreaded "virtual" cores almost idle. Totally the opposite of what you see on your laptop. Very strange! |

More info: I just installed on a newer machine (1.8GHz i7, single dual-core processor with hyperthreading) and I'm getting 45Kh/s out of it. Activity monitor reports Securecoin-Qt using close to 300% of CPU so it does seem to be taking advantage of hyperthreading. I don't have any third or fourth cores to allow one app to use more than 200% of CPU.
(I just closed down a bunch of apps and I'm getting closer to 60Kh/s now on the laptop—not sure what the CPU usage is exactly because Activity Monitor itself is one of the apps I closed—closing Activity Monitor gains me about 5Kh/s)
That's awfully strange. I tried it on a quad-core CPU with hyperthreading, and got about 120Kh/s at about 400% CPU usage. I'm not sure what to tell you; one thing you can try is specifying the number of mining threads in the setgenerate command, e.g. for 4 threads. Ultimately you'll probably be better off with the Securecoin version of cpuminer, if you can get it compiling--it's way better optimized than any of the wallets. |

UPDATES: - NEW: Securecoin 0.8.3.0
- UPDATED: Worldcoin 0.6.4.5
- UPDATED: Gamecoin 0.8.3.1
Wow, maxpower, that was fast. Thank you! Running smoothly on my Mac Pro. The only issue I have to report about it is that the built-in miner doesn't appear to try to make use of all the CPUs. The Windows version (running under Parallels) got around 110Mh/s; the Mac version gets 35Mh/s and Activity Monitor reports lots of idle CPU. That's only an issue because I haven't successfully compiled one of the forks of cpuminer. But using your Securecoin port is still a huge improvement. When I was running the Windows cpuminer (under Parallels) against the Windows Securecoin-QT I was getting 90-100Mh/s. Running that same Windows cpuminer against the Mac Securecoin-QT I'm getting 120Mh/s. Admittedly a somewhat surprising result but until I can get cpuminer to compile this is the best setup so far. So once again… thank you! That's strange; I just tried the Securecoin-Qt miner and it's using all my cores (or at least all my physical cores--it doesn't seem to count hyperthreaded "cores"). How are you starting the miner? I'm opening the debug window and typing: |

Matched ryanb's 1000 ZET with 1000 ZET of my own, sent from the Mac wallet. If you don't receive it, let me know and I'll file a bug report.  I got it, thank you very much! I'll take a look at Securecoin as soon as I have a chance. |

UPDATE: Updated Worldcoin to latest (0.6.4.4).

Sure, I'll take a look at it today. Added a QRK wallet to OP. Mining seems to work for me, though I don't have the hashpower to find a block ATM. Let me know if you have any trouble. The app has the mining inside of it? Thought this coin was CPU mined? Yeah, you can open the debug console and type "setgenerate true -1" to start the wallet mining. |

my friend twobits built the new noirbits fork for me because i got into mining them and stuff so I think you should add it to the list so others can use the new noirbits on the mac the link is here https://app.box.com/s/gjlaldl0u9ft9mjap3qw Added to OP, thanks! |

UPDATES: - Updated Gamecoin to latest version
- New AndroidTokens wallet

I just tried and it seems working fine so i sent you 1000 ZET instead of 500 thanks
Thank you! Glad it's working. |

Is anyone else having a problem with AnonCoin? Its been stuck downloading the block chain on number 15530 20.49% with 10 active connections
I think AnonCoin has forked since I last built it. I would recommend using the official AnonCoin Mac wallet from their website. See https://anoncoin.net/Downloads.htmlEDIT: Updated the OP to reflect this. |

can we have ZET Mac wallet please?
Yeah, I've actually been playing with it a bit already. There are some Mac-specific weirdnesses I've been fixing. Let me see if I can get something working and post it for wider testing. One we get it going i will give you 500 ZET as bounty Thank you Thanks! If you don't mind being a guinea pig, please give this a try and let me know what you think. It seems pretty stable to me and syncs the blockchain with no problem. https://www.dropbox.com/s/nmu7rcr1jl17uhy/Zetacoin-Qt-0.8.2-Mac.zipOne thing to be aware of is that the ZET wallet is based on 0.8.2 of the Bitcoin wallet, and the official Bitcoin wallet build has been intermediately crashy on my Mac (causing me to lose my blockchain a couple times; never any wallet issues). This may not be such a big issue for Zetacoin since the blockchain is still pretty short, at least compared to BTC. If it works for you, let me know and I'll put it in the OP. And my ZET addr is ZDT5LyinCYT4EP7tnmCDngJcwhWMqF9DAT if you feel this is bounty-worthy. |

Your wallet is good my friend!
Great! It's hard to keep up with all the coins and their updates sometimes...glad to know GLD is in good shape. |

Any chance you can update the GLD wallet?
I have been asking the GLD team for weeks and they have not done it for some reason...
Weird, I pulled the latest GLD source from Github, but it looks pretty much the same as what I compiled as 0.6.9.3 on 8/3. They've rearranged a few files, but I don't see any new checkpoints or a new version, just some new graphics. Here's what I compiled today from the latest in Git: https://www.dropbox.com/s/bggwkpvv0yq2yhi/GoldCoin-Qt-0.6.9.3-20130817-Mac.zipLet me know if this is what you're looking for! Maybe I missed something in all the diffs I ran. |
