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

[abbeytim]

hi i was wondering if it can take advantage of the intel avx extension? or be compiled with it thx

is anybody else haveing a problem with avast tagging cpuminers as a trojan? ufasoft is also being tagged

dosnt matter.

Some malware people have been including the miners (including cgminer) as a payload in their trojans to get their botnets mining for them.

I keep sending false positive reports in, explaining that they are just payload, and if they are going to keep flagging them, at least flag them as a low threat so we can just click 'ignore'.

Yer just going to have to add them to the exclusion lists. You'll have to put it in at least two places. One is the shield settings, and in the scan settings. I couldn't tell you exactly where right now, I am not at that computer.

I just put the entire folders for them as exceptions, and also excepted all of the blockchain files too, or avast will be constantly scanning them whenever they change.

ps: only download the miners from the official sources/threads!

% of accept hashes goes down, therefore to logic boooo is a stale, yay the opposite.

Also when I used sha256 I got too many Yay and too many (booooo)s in follow...

Most of my mining hardware runs on Linux, but I have a Windows box on my desk at work.  I'd rather have minerd running as a daemon, but the Windows binary doesn't provide that as an option.  I could launch it minimized with a batch file called by a shortcut, but it still shows up in the taskbar.

A little bit of digging turned up some VBScript that can launch a program invisibly: no window, no taskbar, nothing to indicate it's running other than an entry in the task manager.  Some more digging turned up a way to renice the program so it doesn't interfere as much with normal usage.

Code:

' launch minerd

Set WshShell = CreateObject("WScript.Shell")
WshShell.Run chr(34) & "C:\Program Files\pooler-cpuminer-2.2.3-win32\minerd.exe" & Chr(34) & " -a scrypt -o http://ltc.kattare.com:9332/ -O username.workername:password", 0
Set WshShell = Nothing

' renice it to idle priority

strComputer = "."
Set objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colProcesses = objWMIService.ExecQuery("Select * from Win32_Process Where Name = 'minerd.exe'")
For Each objProcess in colProcesses
    objProcess.SetPriority(64) 
Next

Change the path to minerd.exe as appropriate.  I'm using the burnside Litecoin pool; change the pool URL and authentication options as appropriate.  Save as minerd.vbs, add it to the startup group, and it'll run hidden when you log in.  If necessary, use the task manager to kill it.

The only downside is that you don't get to monitor mining progress, as logging support isn't implemented in the Windows binary and there's no window to check.

Where can I find a guide on how to use minerd? I have tried --help but I cannot determine how to use it to mine solo. Also, where do I specify the address where found blocks will go to?

thanks.

you need a litcoind that would push works and get the mined litecoins in its default address
the usage would be :

Code:

minerd -o http://litecoindserver:port -O ANameOrAnotherLitecoinAddress:x

Thanks. What is AName for the parameter -O ? and what does :x stand for?

As far as I know you can't specify an address to mine to when using litecoind directly. You need to use the username and password in your litecoin.conf file.

Hi pooler,

as stratum is getting available to more LTC pools (ltcmine, notroll.in, p2pool) - do you have any plans to support it in future cpuminer (or rollproxy) releases?

I'd like to implement it, but I can't say when I'll be able to. I'm pretty busy in this period.

I must be utilising this wrongly;

it tells me its initialising 4 threads but nothing more, even minutes later. do i need this in the litecoin directory?

full command line ur using or this is just guessing.

cgminer --scrypt -o http://mine.pool-x.eu:8337 -u klondike_bar.1 -p x --shaders 40 --intensity 13 --worksize 64 -g 1 --gpu-engine 285 --gpu-memclock 760

its an nvidea NVS 3100m. default clocks are 300/800, but i found decreasing them slightly has little effect on hashrate but drastically improves on hardware errors (went from about 1 accept per 4 errors down to 5 accepts per 1 error)

invalid, this is the wrong thread! this thread is for cpuminer (minerd) not cgminer!

ahh durr my mistake, heres the CPU batch file command:

@echo off

START /LOW /B minerd.exe --algo scrypt --url http://mine.pool-x.eu:8337 --userpass klondike_bar.1:x --threads 4 -r -1 -s 5


its essentially the default configuration as im not sure how best to utilise my  i7 620m (2.67GHz)

Ive got it working now, but at ~3.2khash/core (~13 khash/s) it feels slower than what i would expect (i imagined 20+ khash/s)

-r -1 <-- dont specify this. dont set --threads too, so it uses all threads and maps each thread to a core (it does this on unix, dunno if this works in winblows). there is no need to set -s 5 too since this is default.

so just:   @echo off

START /LOW /B minerd.exe --algo scrypt --url http://mine.pool-x.eu:8337 --userpass klondike_bar.1:x

im running about 13.6 khash/s now, about an 8% increase. any other tweaks i should be aware of?
