Topic: CGMINER - Remove CPU mining? (Read 18649 times)
It should be removed as it's not feasible to maintain the code in the long-run. It's obvious that CPU mining is obsolete. There are alternative CPU miners which can be used.
Strip it out and get rid of it. People that need CPU mining have other miner software they can use.

Who's a cute little Spock quoter? You are! You are!
Maybe the readme can be updated to segregate the cpu related params given they have no effect on default builds (and pre-built binaries)?
Good idea. 
The disable gpu option wouldn't be a cpu only option, as it would also be good for someone mining with FPGAs that wants their video card to do 3D work.
Good point. I got to stop thinking so binary. CPU vs GPU.

I'd say the votes are pretty conclusive. Thanks everyone for your input. For simplicity I'll be making it a compile time selection for now, default off. This has already been committed to the git tree and will be in the next version. I will no longer be releasing binaries with CPU mining support built in and if it proves innocuous in this fashion, it will be left that way. Should issues arrive, it will be deprecated entirely in a future version.
Sounds sensible. Complete removal would clean up the giant list of command line & config file parameters. Maybe the readme can be updated to segregate the cpu related params given they have no effect on default builds (and pre-built binaries)?
Code:
--algo|-aSpecify sha256 implementation for CPU mining:
auto Benchmark at startup and pick fastest algorithm
c Linux kernel sha256, implemented in C
4way tcatm's 4-way SSE2 implementation
via VIA padlock implementation
cryptopp Crypto++ C/C++ implementation
sse2_64 SSE2 64 bit implementation for x86_64 machines
sse4_64 SSE4.1 64 bit implementation for x86_64 machines (default: sse2_64)
--cpu-threads|-tNumber of miner CPU threads (default: 4)
--disable-gpu|-G Disable GPU mining even if suitable devices exist
--enable-cpu|-C Enable CPU mining with GPU mining (default: no CPU mining if suitab

To be honest I didn't even really know that cgminer was CPU capable, as I've never had to use it 
Obviously I'm happy for it to be removed.
As a person who has a couple of BitForce units ordered though, I'm extremely happy to see support for that included, top work Luke/Con

ok I got it to ufasoft to work & its giving better hash rate than cgminer
color me GONE
You are allowed to change your vote too color me GONE
thats a great recommend ufasoft
first install another program to unzip it, then figure out it's command line, then find out it don't work
on the cpu says 2 threads running unless 0 is a correct hash rate -- NOT

Just for shits and giggles I tried it. Took about 30 seconds to get it to work.
I limited it to 1 thread because I didn't want it to CPU starve cgminer.
Just because you can't figure it out doesn't mean it isn't a good miner. Hell everyday people can't figure out cgminer I guess that means it sucks too.

D&T's persona here can sometimes come off as being a bit ... how shall I put it ... terse (no offense intended, D&T). But there's usually little (if anything) wrong or inaccurate with what he says. There's no need for you to be a douche.

If CPU mining can be made modular (sound like this is done), and the CPU mining code tossed into a new git repo, I think you can have your cake and eat it too.
If someone is really dependent on CPU mining w/ CGMINER, they can go find the CPU code and throw it in. If they want feature x,y,z for CPU mining, they can code it or beg for someone to code it on the CPU module project.
I doubt CPU mining code will be the last deprecated (for the majority of users, that is) mining method.

For me, even windows is free 
No, it isn't. To be free, you need to be able to legally: - run the program, for any purpose
- study how the program works, and change it so it does your computing as you wish
- redistribute copies so you can help your neighbor (including selling it)
- distribute copies of your modified versions to others

Thank you.
He may be able to obtain windows at NO COST (either legally or illegally) but it isn't even close to free.
Free as in free speech not free beer.

...first install another program to unzip it...
Robert, this "another program" as you put it, 7-zip, is what currently happens to be the best free, open source, multi-platform archive manager available.
You'll be glad to have it installed so stop being so grumpy
Shame on Microsoft for not having touched their built-in compressor/decompressor for ages.

care to name those "other CPU miners"
Has support for SSE2. It is in active development and now includes CPU alt-chain support which should result in continued development (at least until alt-chain fad dies out).

It is well founded. The inefficiency of CPU (MH/W) and the sheer number of them means the only "legit" operator is one who happens to own (or have legal access) to hundreds of CPU and also happens to have access to dozens of KW of "free" power.
Given that intersection of unlikely characteristics it isn't exactly a stretch to consider that most large scale CPU mining is being done illegally or at least covertly.

cpuminer-ng has some good threading optimizations and SSE4.
