An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

[AKAnotOutkast]

I had a key  llogger on my system and i suspect this software i down loaded as the colprit. IDK jut letting you know. I think something is up, esp since my anti virus locked on minerd  as suspect. some how some one got all my log on info, the only way they could have done that is with a key logger. can someone verify this is safe build?

Sun Fire T1000 6-core @ 1GHz
Oracle Solaris 11.1

at 24 threads each gets .06kh/s =1.44kh/s

They're $75 on ebay, 180W power consumption.

If I mine all month I can turn $10 of power into 75 cents worth of altcoins

Please help...

I started to cpuminer and it worked ok for 1 and a half day... then the electricity went off... i started my PC and run the cpuminer again.. but it just do nothing... i tried every configuration possible... making a separate proxy server... deactivatind antivirus, firewalls. etcs... i am mining LTC--- i have been around 6 hours searching on google but i can not find a solution...

Are you sure the pool you're connected to is working.  The output looks like CPUMiner is working fine.

I have this wonderful code running on several machines now - just soaking up what cycles are free (sorry BOINC!).

However, on ONE of my Linux systems I'm missing something.  I'm guessing I need to install some library or another, but I'm getting:

[2014-01-22 19:39:07] workio thread create failed

Immediately upon launching mined:  ./minerd  --url=stratum+tcp://lite.wemineltc.com:3334 --userpass=Cassey_Jean_Claude.farm2cpu:pass

Any chance for a quick save here?  I know its got to be something trivial... in fact, I think I've seen it before and figured it out, but can't recall what I did.

Thanks,

Cassey

How do I get the 64 bit version to work with doge.netcodepool.org? The command line on their getting started page isn't right, it doesn't recognize --scrypt. Remove one - and it still doesn't work.

Tried this

minerd -scrypt -o stratum+tcp://stratum.netcodepool.org:4093 -u Galane.workername -p mypasswordonlyIknow

and that does nothing at all, not even an error message. This is the CPU miner program that pool recommends, would be nice if they also had correct directions on how to use it.

Windows 7 Ultimate x64 on a Dell Inspiron E1505 with 4 gig (3.25 thanks to stupid Intel chipset hobbling) RAM, Core2 Duo T5600 1.83 GHz CPU. I only really use the laptop when I'm away from home so it may as well earn its keep when not being used.

hello guys,
im a newbie and i have just 1 question?

right now i have the following error:

HTTP request failed:  Failed connect to 127.0.0.1:9332; No error

Sounds like you ran out of resources on that particular box. Care to share some system information? Architecture, distro, kernel version, what kind of other programs you have running at the same time, and the output of free and ulimit -s would be nice.

There's no "--scrypt" (that's cgminer/bfgminer) or "-scrypt" option. The correct syntax is "--algo=scrypt", or "-a scrypt", as you can see from the output of "minerd --help".

I need a CPU Windows Miner. I downloaded it from http://cgb.smalltimeminer.com/index.php?page=gettingstarted
I however seem to run properly or can not fault. someone please help me. I need 64 bit windown.
thank you

[Galane]

Here's what you need for the CPU miner. I'm running four threads, two per CPU core. Increase the number after -t for more threads. Replace stratum+tcp://www.shibepool.com:3333 with your pool server and port number. (This is a small pool, just over 800 workers currently.)

minerd -a scrypt -t 4 -s 6 -o stratum+tcp://www.shibepool.com:3333 -O UserName.WorkerName:YourPassword

[shinkudo]

thank you. but I still can not run on Win 2008 64 bit vps. you please give me the full version to run on vps can not windown 2008. thank you very much. I've downloaded at http://cgb.smalltimeminer.com/index.php?page=gettingstarted but apparently it is not enough to run. thank you very much

It's been said before, but let me repeat it: the -s option does nothing when you mine in a pool (both when using Stratum and when using long polling). It only makes sense to use it if you are mining solo.

Also, for optimal performance it is usually best to have exactly one thread per logical (as opposed to physical) core, which is what cpuminer does by default. The -t option is normally used to start fewer threads, so as to limit the system load.

ooks like you're digging Doge. thank you but I want to dig CGB. you can help me. thanks for reading

Ok, this might be a stupid question but...

I've downloaded the win64 version of cpuminer from the first page in this thread, and I try running it with a batch file containing:

$ ./minerd --url=stratum+tcp://useast.middlecoin.com:3333 --userpass=my.worker:password

as in the first page.

CPU miner very quickly opens then shuts again too quickly to read what is in the terminal.  I get the same response when I run:

$ ./minerd --help

Try minerd.exe   

The ./minerd is for Linux/UNIX/Mac (specifying ./ means "in this directory" for executables).

$ means just the commandline prompt in Linux.  Windows equivalent would be C:\

If you are using a windows system, the easiest way is to go to the folder where you have your miner.
Create a new text file called Miner.txt   
Open the file and paste in   "minerd.exe  --url=stratum+tcp://pool.phsblocks.com:3333 -u gibithecat.gibi -p password" without the " " and changing settings to match your pool.
Save it. Then rename it Miner.bat    You may need to switch off the "Hide extensions for known file types" option in windows.
Now if you click on Miner.bat it should open your mining program.
If it opens in a text editor, it is named Miner.bat.txt  , you just can't see the .txt bit.
If it flashes up and disapears, you have something not set correctly.
If you add "pause" to the  bottom of your miner.bat file, it will stop before disappearing.
That should let you see what needs changing.

Appreciate the help.  Alas, when I just came back from a weekend trip and tried to reproduce, I couldn't.  FYI, it is a Gentoo Linux system built on a AMD A4-6300 APU.  Super low end, only 15 kh/s between the two cpus, but the system is running a 7870 and I couldn't see wasting the cycles.
