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

[The00Dustin]

Ah OK, that explains it then. Can you please point me in the right direction to run minerd from the cmd line? Many thanks!

I don't use Windows, so I can't tell you what you have to do step by step, but you probably want to create a batch (.bat) file and write the command to start the miner in it, complete with all the options you want. There are basic usage examples in the first post.

I would assume that glon wants to solo mine since he wanted to do it from litecoin-qt.  That having been said, litecoin.conf would also need updated with options such as these:

Code:

server=1
rpcuser=Miner
rpcpassword=1234
rpcport=9332
rpcallowip=*

I don't know if this even works in the Windows Litecoin-QT distributable, but if it does, the conf file would be in the same place as the wallet.dat file.  Perhaps a link to some old bitcoin mining 101 type post would be better suited to getting him going (since the solo-configuration is essentially the same).

The guide I used does not mention this config file. And no I do not want to solo-mine... is that even a good idea?

I guess I just need some example cmd line for minerd so I will look into the first page of this topic for hints, thanks.

The Mining tab in the old Litecoin-Qt 0.6.3 also allowed pool mining.
Solo mining with a CPU at the current difficulty would be a bit of a wild goose chase, by the way.

Good to know.  Even single GPU solo mining is a bit of a wild goose chase at this point.

A couple of Windows users reported what is probably the same issue over a month ago: https://github.com/pooler/cpuminer/issues/21
Two other Windows users I asked said they could download the archives and run the miner with no problem at all, though, so I closed the issue when the original reporter stopped answering my questions.
For what it's worth, I have no problem accessing the files hosted at Sourceforge, so I'd be grateful if you could provide some more detail. Operating system, browser information, and what error you get exactly would be a good start.
Please also try to download the files from this page and see if there's any difference.

Sorry, but no difference.
I've tried on Google Chrome and Mozilla Firefox - both tries failed.

On Google Chrome - I've got error "unexpected network error"
On Mozilla Firefox - error "File can't be saved - Mozilla can't read the source file" (I've translate it from my language, so the error may be little different)

I use Win 7 32-bit

Building cpuminer on Solaris8 fails as it doesn't have <stdint.h>, using <inttypes.h> instead fixes the problem.

uname -a
SunOS adeint2s 5.8 Generic_117350-28 sun4u sparc SUNW,Ultra-Enterprise Solaris

./minerd -V
cpuminer 2.3.2
libcurl/7.31.0 zlib/1.1.3

Just in case you care for an eosl'ed operating system.

Sure!
After reading the documentation of autoconf, I think it should be pretty safe to just replace stdint.h with inttypes.h for all systems.

The C99 standard says that inttypes.h includes stdint.h, so there's no need to include stdint.h separately in a standard environment. Some implementations have inttypes.h but not stdint.h (e.g., Solaris 7), but we don't know of any implementation that has stdint.h but not inttypes.h.

Just reporting that the cpuminer 2.3.2 was successfully forked into a CUDA enabled version (called cudaMiner). Thanks for all the work on the stratum protocol - the nVidia users are going to love this! Another feature they keep asking me for is failover support for multiple pools. And some have asked for a logging feature that logs just the most important data to disk (i.e. found shares and whether or not they were accepted) - without all the periodically reported kHash/s statistics.

thank you very much

There's a -q option for preventing the miner from printing the per-thread hashmeter.
To save the output on disk you can just redirect stderr to a file.

Code:

minerd -q [OPTIONS] 2> myfile

Hi pooler i'm using the latest cudaminer client by cbuchner1 which includes stratum support based on your cpuminer. I've gotten an error message "stratum_recv_line failed to parse a newline-terminated string". Since it might be stratum related, cbuchner1 advised to post this here. So far it has happened only twice.

That can happen if the server you're connected to has a hiccup; the miner should try to reconnect automatically in a matter of seconds.
If you suspect a compatibiliy bug in the miner, feel free to pm me your full connection details so that I can try mining at your pool and see what the problem is.

Ok thanks pooler. I'll monitor and see the situation. So far only happened those two times.

Thanks also for implementing stratum into the miner client. No more need for proxy.

I'm getting 100% of boooos. Has it something to do with cpuminer?

Which Pool?

With the latest CPUminer make sure you connecting to a Stratum server

For instance. stratum+tcp://pool.ejpool.info:9332

For more information.

I suspect it is your antivirus or firewall... Avast identified it as a threat. It is just a false positive.

firewall off and still the same thing, dunno how to turn off avast, i am also using Win 7, but 64 bits

Version 2.3.2

• This version includes new AVX2-specific scrypt and SHA-256d routines, which bring an 85%+ speedup to the new Intel Haswell processors. I have tested the new code on a Core i7 4770 (4 cores, 8 threads, 3.4 GHz), and the results seem pretty good: over 95 kh/s for scrypt, and over 50 MH/s for SHA-256d.

95 kh/s per core or in total?
