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

I know people always say CPU mining costs more in power, but now that the speed is this high is it worth it to CPU mine? When I had first got here and only knew how to CPU mine with the Bitcoin client and I got 6 mhash/s , which was higher than most others and they still told me don't bother. Now I am mining @ 285 mhash/s GPU add in the CPU and it's an even 300 mhash/s , so should I continue to CPU mine just GPU? What do you guys think?

I lowered the voltage on my CPU and temps are great at max load and I was able to mine with GPU and CPU stable for at least 18 hours straight so I know its stable.

Any opinions?

I would only mine with cpu if the added speed is significant. In your case, its just 5% faster, and your cpu is probably using at least 70W. It's up to you.

How did you figure out how many watts I would be using? That is something I don't really understand too much. I would like to be able to figure out how much my whole pc is using.

My CPU at full speed is at 1.104V
My GPU is 1.163

every CPU made has published figured on how much heat they output and heat output==power input.

Were there improvements for the windows side as well? Could you please update release dates and version numbers in the first post of the thread to make it easier to keep track of whether or not people have the latest version? I'm currently running version 0.4.

Thanks.

I wonder if this is as much performance as we're going to ever get out of CPUs.

Also I'm wondering how the new Sandy Bridge chips perform with this miner. Anyone have such a CPU and can report how ufasoft's miner performs on it?

[ufasoft]

Could you please update release dates and version numbers in the first post of the thread to make it easier to keep track of whether or not people have the latest version? I'm currently running version 0.4.

Version 0.6 released.
Added: Improved performance on AMD Evergreen+ GPUs.

The first Post will show version and release month.

I'm presuming that performance on Intel CPUs is staying the same?

Yes, some improvement for CPU can be made only for:
1. x64 because it has more registers.
2. CPUs with AVX

Nice! So Sandy Bridge CPUs should provider better performance..assuming that your miner will be updated to support AVX.

Hello

I am trying to compile your Linux source

It says I'm missing JWASM

Can't find it on apt, and i have found several implementations of the asm interpreter,  I was wondering which version you use?

[BOARBEAR]

I think I found a bug.
If you do not have bitcoin ready, and run the miner, then get bitcoin ready
it will crash on windows vista x64

Version 0.7 released.
Supports Long polling Protocol
Some bugs fixed

ah, finally!  Much thanks

[ufasoft]

Just tried to compile this on Linux x86-64.

Not tested on x64 yet.
I will have time for it on next week.

BTW:
Version 0.8 released. Added support of Failover extension

[aeMaeth]

Version 0.7 released.
Supports Long polling Protocol
Some bugs fixed

Just tried to compile this on Linux x86-64.
It dumps a ton of warning and fails with the following errors:

Code:

el/inc/../libext/ext-fw.h:924: error: cast from ‘void*’ to ‘int’ loses precision
bitcoin-sha256.h:52: error: ‘_rotr’ was not declared in this scope

I have the same error

Code:

In file included from bitcoin-miner.cpp:33:
bitcoin-sha256.h: In function ‘Ext::UInt32 Rotr32(Ext::UInt32, int)’:
bitcoin-sha256.h:50: error: ‘_rotr’ was not declared in this scope
make: *** [bitcoin-miner.o] Error 1

This will help some people

Thanks I was looking for this, but it will help even more if you tell me how you made it print that info. I tried bitcoin-miner /? with no luck.

Are there actual docs for this program (besides this thread)?
