Topic: New demonstration CPU miner available (Read 386150 times)

For what is worth, I use your CPU miner, mainly for scrypt, but sometimes for SHA-256 too. I don't care that if it isn't profitable, not doing it mainly for the money. I wish it had some of the nice features that BFG has like dynamic pool handling, API access, log and share files output, etc. I'm actually trying to compile BFGminer with CPU option even though I haven't use C in 20+ years. That's how much I like the idea :-).

For Litecoin Mining it is still nice and it's easy to compile.

ahhhh the good old days..

cgminer lost its CPU mining code a long time ago now.

Trust me, you don't need it. Plus, you are better off compiling cgminer with CPU support as it has faster algorithms I believe.

I cant find Linux installation guide for this miner 

What other coins can be mined using CPU Miner? I cant seem to find a list anywhere and really cant look through 30 pages of posts

And botnets

Pull requests for cpuminer are still welcomes.

cpuminer is definitely used on testnet and various other alt-coin scenarios.

Then it work in the correct way: cpu mining today is useless 

this program crash when i open it

It's useless even for security purposes.

Because the only reason we're here is because of money!

Seriously, CPU mining is useless

I'd say so, judging from this post:




Honestly I don't think this is necessary, since very few people still mine Bitcoin on CPU. In addition, cgminer has never been the only miner with CPU support (there's Ufasoft's miner, for instance).
I also think that, as a core Bitcoin developer, your time would probably be best spent elsewhere.
All this to say: I would be more than happy to take this project over, especially considering that I've rewritten a lot of the old code already.

Really?

Maybe we should reactive jgarzik/cpuminer then. and start merging pull requests.

I started a fork of jgarzik's miner a few months ago. The original goal was to provide an optimized miner for Litecoin, an alternative chain that uses a completely different hashing algorithm from Bitcoin. Over time, however, I have also added a number of new features and bugfixes. You can find a complete list of all important changes in the NEWS file; they include:

• Optimized work handling, resulting in a much better getwork efficiency.
• Support for HTTP and SOCKS proxies.
• Support for many different operating systems and architectures, including big-endian ones. The miner has been reported to build successfully on Linux, FreeBSD, Solaris, Mac OS X and Windows (using mingw).
• Clear --help output. (Please read it before using the miner!)

Now for the reason I'm writing this here.
Starting with version 2.2 of this fork, I have re-included support for Bitcoin mining, writing a new implementation of the hashing algorithm. This implementation is different in that the single --algo=sha256d option should provide the best performance on all systems.
On K10-based processors (such as the Phenom) this fork is only slightly faster than the old "4way" algorithm, but on all other systems you should notice a significant increase in mining speed. The miner is also capable of using AVX and XOP instructions on CPUs that support them, resulting in an even greater speedup.

Here's a link to the git repository:
https://github.com/pooler/cpuminer
Under the "Downloads" tab you will also find a source tarball and a couple Windows binaries.

I don't know if anybody is still interested in CPU mining. The main reason why I want to maintain this miner is because I enjoy coding; also, I like jgarzik's miner because, unlike many others, it conforms to the KISS design principle.
Given that CPU mining support has been discontinued for cgminer, I hope that people will find this fork useful.

Yep , great feature, but I am dying to generate my first block shown
on the blockexplorer event if it is only on the test net.

It's probably not even worth trying assuming Gavin's testnet difficulty calculation changes aren't live yet.

Try Testnet in a box. You can "use CPU mining to create blocks every 10 minutes as normal or a GPU miner for blocks every few seconds".

Finally got it to work with the .conf file. Let's see how much time will take to generate a block on a testnet.

Thanks a lot !!!
