FAQ / Troubleshooting

Q: Should I call this miner "cpuminer" or "minerd"?
A: The software package is called "cpuminer". "minerd" ("miner daemon") is just the name of the executable file provided by the package.

Q: My antivirus flags the Windows binary as malware.
A: That's a known false positive. More information here.

Q: Can I mine (insert your cryptocoin here) with this miner?
A: Only if its proof-of-work algorithm is scrypt or SHA-256d. This miner does not currently support other algorithms such as Keccak, scrypt-jane, X11, etc. Forks of this project may provide additional algorithms, but I do not maintain them and they are not discussed here, so if you have questions about them please contact their authors.

Q: When running configure I get the error "C compiler cannot create executables".
A: Make sure you typed CFLAGS="-O3" with a big O, not with a zero.

Q: autogen.sh dies with "error: possibly undefined macro: AC_MSG_ERROR".
Q: configure chokes on something like "LIBCURL_CHECK_CONFIG(, 7.15.2, ,'".
A: Make sure you have installed the development package for libcurl. If you have and you're still getting the error when compiling from git, try compiling from tarball instead.

Q: I'm trying to connect to a Stratum server, but I get "HTTP request failed: Empty reply from server".
A: Make sure you specified the correct protocol in the server URL (stratum+tcp://).

Q: Is there any command-line option I can play with to make it mine faster?
A: No. The miner automatically picks the best settings for the CPU it is run on.

Q: What's the difference between the two algorithms, scrypt and sha256d?
A: They are completely different proof-of-work algorithms. You must use scrypt for Litecoin, and you must use sha256d for Bitcoin. The default algorithm is scrypt, so for Bitcoin mining you have to specify --algo=sha256d.

Q: Will this miner use a lot of RAM when using the scrypt algorithm?
A: No, that's a GPU thing.

Q: How do I make the miner write its output to a file instead of printing it to the screen?
A: Just redirect the standard error stream to file:
Code:
minerd [OPTIONS] 2> myfile
You may also want to use the --quiet/-q option to disable the per-thread hashmeter.
On *nix, you probably also want to use the --background/-B option to fork in the background.


Original post (December 19, 2011) follows. Please note that most of the technical details are now outdated.

I have recently rewritten the heart of the scrypt hashing function used by the jgarzik/ArtForz cpuminer in assembly language, to see if this could bring some more speed. Apparently it did. Smiley
The source code is now available at GitHub:
https://github.com/pooler/cpuminer
The build process for Linux should be the same as before.

In the new code I tried to take full advantage of SSE2 instructions, which are available since the Pentium 4. Unfortunately, AMD's implementation of these instructions is not as fast as Intel's... well, ok, sadly it's nearly two times slower. For this reason, I had to write separate versions of the hashing functions. You don't need to worry about this, though, since the new function should be able to auto-detect your cpu and automatically select the best algorithm.

Long polling patch
This release also includes a new --timeout option that I originally added to solve a problem with long polling. Apparently the LP thread doesn't behave nicely under certain network conditions, as reported by various users. So, if you experienced high stale rates with the previous miner, you should definitely try out this new version.
Many thanks to SockPuppet, aka shawnp0wers, who helped me nail down the issue!

Some Technical Details
The current release includes four different implementations of the scrypt core, each one designed for a different hardware.
  • A fallback plain x86 version, to be used when SSE2 instructions are not available (Pentium III, Athlon XP and earlier processors).
  • A 32-bit version using SSE2, for use on the Pentium 4, Pentium M, Core, Atom, plus all 64-bit cpus running in a 32-bit OS.
  • A 64-bit version for Intel processors, i.e. Core 2, i3, i5, i7. This version can in most cases double the speed of the previous miner.
  • A 64-bit version for AMD processors, i.e. Athlon 64, Phenom, Sempron and the like. The speed increase here can range from 5% to 80%.
The first two versions only get compiled in the 32-bit miner, the last two only in the 64-bit miner. The miner uses the CPUID instruction to choose which version to use.

Compiler Flags
One cool aspect of assembly code is that users no more need to play with compiler flags to get the best performance. Configuring the build with just CFLAGS="-O3" is now more than enough to get efficient code. This also means that we no more need separate specialized binaries for Intel and AMD cpus. Just a 32-bit and a 64-bit version.

Personal Notes
Someone on IRC asked me why I am releasing this miner, instead of keeping it for myself or for my pool. Well, that's exactly the point. It is important for Litecoin that everybody has access to the most efficient mining software!
Someone might worry about the effect of this release on market prices, but consider this: if everybody starts using the new miner, the hash rate will go up, but so will difficulty, so nothing will ultimately change. I actually think this new miner will be very beneficial to Litecoin, because it should make mining easier for beginners (see compiler flags).
As crazy_rabbit wrote in another thread, one big plus of Litecoin is that everybody can participate. Well, consider this: now you can effectively mine on an Atom! Smiley

Alright folks... I hope you enjoy the performance boost. Consider this as my Christmas present to the community! Cheesy

96  Alternate cryptocurrencies / Mining (Altcoins) / New X11/Darkcoin AMD nVIDIA GPU Miner With 40%-50% Performance Increase on: May 22, 2014, 09:07:33 PM


It seems that the OpenCL kernel for Darkcoin for sgminer has been optimized by a user called girino over at the forum to bring some nice performance improvement in the hashrate when mining X11 crypto coins such as Darkcoin. Do note that you need to use a precompiled miner with no source code and there is a 2% developer fee on the mining (the miner mines at another pool for the developer), but with 40-50% performance increase over the latest sgminer with support for DRK the 2% dev fee is acceptable. We have tested the new x11-sgminer on a Radeon R9 280x and and we are getting a boost from about 2-2.1 MHS to a little over 3.1 MHS with the new miner. The author provides compiled version of the miner for both Windows (download the mingw compiled build) as well as for linux and as already mentioned there is no source code published yet, so you cannot compile it yourself and you nee to download a binary release.

97  Alternate cryptocurrencies / Mining (Altcoins) / ccMiner 1.0 beta Fork with Support for Older Compute 2.x GPUs on: May 22, 2014, 03:55:37 AM


The support for older Nvidia-based GPUs using Compute 2/2.1 architecture (Fermi) has been dropped in the more recent versions of ccMiner in order to focus and improve performance on the newer Compute 3 and 3.5 (Kepler) as well as 5 (Maxwell) GPUs. It seems however there are still quite a few people that are using Fermi-based Nvidia graphic cards to mine crypto coins with, so this is something they may find useful. There is a fork of ccMiner compiled with support for Compute 2.0/2.1 (Fermi) GPUs as well as the newer Comupte cards. To ensure support for Compute 2.x however the support for Jackpotcoin, Quark and Animecoin is not available as the code for these in ccMiner apparently requires at least Compute 3.0 support. This fork however adds Diamondcoin support that is not available in the original ccMiner release.

I appreciate instacash's work on the mac wallets and I gather (s)he has a lot of projects so I'm sympathetic to them here. However, it's a moderately significant problem for the darkcoin community (especially on days like yesterday!) if there is an update and then a lengthy delay before the mac wallet is released. Even more so when the mac wallet is MISLABELED on the darkcoin website.

Is there any kind of plan to provide in-house mac releases in the future? Is there any way that mac users can update the wallet themselves?

That's the rough part right now because we're closed source until Evan feels it's robust enough for every other coin to clone.... er... I mean use.

I think Evan or InternetApe got a mac to compile on, sorry it was mislabeled  Lips sealed  As soon as things are open sourced, it will get easier, and I know Evan wants to get things opened up as fast as possible, he just doesn't want something with a big issue in it to be gobbled up by every other coin, and discover a terrible hole in it!  Not only would that hurt all the other coins, but would hurt us worse!  Bad reputation, conspiracy theories, you know how this works!  It would be devastating to DRK

So sorry about the Mac wallets, etc.... Not to diminish the importance whatsoever, I might suggest you everyone put Ubuntu on a flash drive to boot on your computer so in a pinch you could use your wallet.  If you play with it a little now, so you might get used to Linux, it may save you panic in the future.

Maybe not you in particular, but saying this to everyone.
