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

[mtve]

Thanks, triple speed up here at intel core 2 T9550 2.66GHz

Update: weird, Lenovo T500 laptop goes 90 degrees centigrade CPU and switches off, twice in a hour.   Getting back to cpu miner, temperature stays at 80 degrees and it worked for weeks.

Well , thats a boost - up to 24Mh/s from 8Mh/s with a 2600k@4.8ghz .

[chromicant]

Oh. Sandy Bridge...

...if there are willing testers, I could try to port the code to those chips. If I recall, the SB'es have 256 bit wide XMM registers, so we may be able to use those for an 8 way hash. However, don't have the hardware available to me.

Yup , intel AVX .

I`d be glad to try it out .

Yeah, this program runs my CPU (T9300 2.50 GHz so similar to yours) far hotter than any other application I've used, so I restrict it to one core which keeps it at about 70 degrees, and give it ample breathing room around the ventilation ports. 

[chromicant]

Yea, this code really just runs full bore in my i5. I've got a massive heatsink (Scythe Mugen 2) on mine, so hitting all 4 cores at once isn't that bad. Biggest issue is that sound of my electric meter going WHIRRRRRR over the fans.... So I could see not-so-good colling solutions not working (this code runs the CPU at 100%, and most thermal solutions seem to be designed for a lower % utilization case to save on weight/cost...).

However, wanted to let people know that my ugly code is now in jgarzik's tree. You can verify it at:

https://github.com/jgarzik/cpuminer/tree/

I'll probably be making some minor changes every so often, and I'll put in pull requests when features are ready. The biggest x86 updates I'm looking at are support for the Sandy Bridge hardware, porting the code to NEON (which has the same rough structure as the X86_64 code), and possibly porting the code to x86_32 if anyone has SSE2 and only a 32-bit machine.

However, I have a bunch of other projects I'm interested in I want to get to first...

Cool, just sent you the other 25 BTC. Thanks for your great work

I get 19.2~19.3Mh/s constant (while running GPU miner as well) with my i7 920 @ 4ghz. Unfortunately it also lowers my GPU mining by 10Mh/s (260 to 250), and My CPU consumes 200W while my GPU <175W

[Lardie]

Went from 3 MH/s to 10 on an AMD Phenom x4. But it only seems to work when I use 127.0.0.1. When I try to send it over a lan to a local server @192.168.0.5 it doesn't work. Also, why do I have connect to port 8332 on 127.0.0.1, doesn't Bitcoin use 8333?

Thanks for the great work!

After a computer restart I'm getting 20Mh/s lol 0.75 more than before

[ufasoft]

There appears to be a small memory leak somewhere in this program. I haven't looked at the code yet to try and find it.

Version 0.4 uploaded:

• The Memory leak fixed.
• ATI/AMD GPU adapters now supported, but performance is not better than on other OpenCL miners

[nster]

0.4 is about 10% faster but affects my GPU mining (by 7Mh/s, from 274 to 267)

[curator]

Excited about the update!

Ufa: is there a place to go (other than here in the forums) to keep up on your miner updates?

Thanks

I think this forum is best place for all btc-related info.
And updates will be rare.

I can confirm that Version 0.4 is about 8-9% faster on an Intel Core2 Duo 2.2Ghz. Now getting ~5.0MHash/Sec compared to ~4.6MHash/Sec with the previous version.

[theGECK]

Average speed for me with 0.4 is almost a full Mhash/s under 0.3.1 (the version I was using). It also dropped GPU mining by 20 Mhash/s. I have a Core2Duo as well.

Did I miss a release or two (or more) between 0.3.1 and 0.4?

[theGECK]

I found my copy of 0.3.2 in my dropbox to use instead of the 0.3.1 I had. Did I miss some other releases though?

Nope, I think that's all.

I'm not running a GPU Miner on this machine, so I can't comment as to performance when running both GPU and CPU mining at the same time.

how to make 0.4 Ufasoft only use the CPU?

[Lardie]

type "-g no"

On my 5870 I am only getting 90 MH/s as opposed to 312 with poclbm.

EDIT: It seem that if you are CPU mining and you don't disable GPU mining it works much slower.
