Ufasoft Miner - Windows/Linux, x86/x64, SSE2/OpenCL, Open Source

[ufasoft]

-Make the delay between work requests settable by the user through the command line instead of it being set statically at 30 seconds as it is now. This would allow the period to be decreased and prevent the unaccepted work problems that I've been having in slush's pool while using this miner.

-Make different levels of output verbosity so that the program doesn't have to throw out a huge amount of hex into the terminal. This is obviously mostly cosmetic, but it would be nice.

Implemented both these options:

Code:

bitcoin-miner -a seconds -v ...

Many thanks, sir.

Anybody succeeded porting it to Linux? I have no success so far.

Well, all of the tools are available now. It would probably require changing the given assembly code around so that it fits the syntax that the GNU assembler requires, and then integrating this miner into another open-source mining system like JGarzik's miner which is natively for linux. Unfortunately, I don't have a lot of time to do this in the next few weeks since university is really heating up in these parts, but that's the basic meat of the task, if anyone cares to challenge it.

My cpuminer work on Windows (32-bit) as well as Linux.

No build environment yet for Windows (64-bit), alas.

Is there a way to acquire work from Bitcoin's local server please? I can't register on Slush's server currently. The image below shows what i did. It also shows 2 kinds of miners working with the local server successfully (CPU and GPU based).

Did you try http://127.0.0.1:8332 instead of just 127.0.0.1?

[os008]

I solved it by using ...

Code:

bitcoin-miner.exe -a 4 -t 2 -v -o http://127.0.0.1:8332/ -u *** -p ***

Instead of ...

Code:

bitcoin-miner.exe -a 4 -t 2 -v -o 127.0.0.1 -u *** -p ***

I can't connect to the server from another computer however. I use ...

Code:

bitcoin-miner.exe -a 4 -t 2 -v -o http://192.168.0.163:8332/ -u *** -p ***

I have no firewall, can ping the server fine from the other computer. It says "connection can't be established" though.


EDIT:
Thanks xenon. Posted without seeing yours, sorry. The problem now is across a network.

Have you tried doing a telnet to the port just to see if it is listening properly?

c:\> telnet 192.168.0.163 8332

If it worked, you will get a blank screen with a blinking cursor. Press ctrl-] to exit.

Thank you for the hint; it's going to benefit me in other stuff also .

It worked on other open ports (Other applications), but not Bitcoin's port . Why would it work locally but not over a network? I even changed the port to 9523 to test, and indeed i had to change the ports in the miners' settings to connect properly (locally). Still over the network the new port isn't working.

That means one of two things.

1. There is a firewall between the two computers blocking communication on that port. On the computer running Bitcoin or in the network between Bitcoin and the Miner.
2. Bitcoin is only binding specifically to the 127.0.0.1 interface and is not binding to the 192.168.0.163 interface.

Edit: I guess it could also mean a 3rd thing..... Possibly, 192.168.0.163 isn't actually the IP Address of the computer running Bitcoin. Or the Miner's arp cash is pointing to an different computer....

Hello, ufasoft.

I'm trying to use your miner with my pool http://deepbit.net but looks like your implementation of HTTP protocol differs from other miners.
Why aren't you sending "Authorization" field in http headers ?

My cpuminer work on Windows (32-bit) as well as Linux.

I get around 1 Mhash/sec/thread with your cpuminer on a Core 2 Duo machine running Linux, using either the C or the cryptopp algorithm.  It would be great to have the SHA256 engine from this thread's SSE2 miner in your cpuminer.  Is it possible?

Cheers,

Yes, it's possible.  ufasoft has released assembly source code....  just takes someone with free time and knowledge to integrate into my cpuminer repository.

I'm currently poking it. I'm assuming it's in MASM format, and trying to port it to YASM now. If I get something that makes sense, I'll put it in my github repo.

Standard GNU assembler should accept MASM format, with a command line switch or two...

Wow... Your miner took my Core2 machine from a mere 2.1MH/s to over 8!

Even weirder, it performs slightly better than the pure-CPU miners on my Athlon64X2 - Which completely sucks at the standard 4-way SSE version.

I don't have many bitcoins yet (finally passed a whole BTC just this past week), but I've sent a dime your way.  Thank you!

8 mhash/sec per thread???

The comparison seems off.  You know that cpuminer only prints out per-thread khash/sec not total, right?

Ah... I did not, actually.  So I guess that makes it only a 2x speedup (the reported numbers went from 2.1 on just about any miner running two threads, to 8.0 reported by ufasoft's miner also running two threads).  Still... A 2x speedup!  Not complaining.

Not that I can see in the fine manual. The code uses some of MASM's IF defines to help make the code portable, which makes things a tad more annoying. As for speed, on my Core i5 760, the speedup was not insignificant...maybe 2xish.

The Core2 Duo laptop that I put this on went from ~1.8MH/s (~900KH/s per thread) to ~4.7MH/s (total)
