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

[K1773R]

old version of pooler's cpuminer was optimized for intel cpu only, but the recent version is also optimized for AMD cpu.

on my i7-920@2.0GH(a dell-M6500 notebook),8 thread
pooler's miner is around 24kh,
while ufaminer is about 0.016mh

0.016mh are the same as 16kh

Is your pooler's cpuminer  built for x64?

My implementation uses only 8 SSE registers available on x86.
x64 has 16 SSE registers. May be that is the reason of performance difference.

yes! pooler's miner is built for x64,
when I use 4 thread, the hashrates are simillar.

btw, did you make a "x64 builds for Linux" in 0.24?
I didn't find the binary executable in the lzma package.

You can build source code to x64 linux, but anyway it uses only 8 SSE registers currently. So it will not increase performance.
Just wait v0.25 for x64 improvements...

there are no builds, its just wrongly described, it should be something like: x64 support or something similiar.
before some ppl made buils of 0.20 and 0.21 and nothing more, atm now im making portable builds but havent done the 0.24 yet, will do this now

[omo]

alright.
I attemted to compile the source, but failed in the configuration step, some of the packages in my centos6 box are too old, and I'm afraid upgrading manually may corrupt something....

atm it cant be built with gcc4.4 (stable) so im waiting until ufasoft fixes this (im in contact with him), if he fixed it il release the 0.24 portable build you can find them here: http://darkgamex.ch/ufasoft/
i think ufasoft should link that to the first page because compiling it on linux, if you dont know the dependencys, is horror and the x86 AMD SDK package is buged (x86 package got x64 libs? retarded amd/ati...).
even when you got the AMD SDK package installed youl have to copy over libs to the builddir and another thing (cant remember it, was trial and error) until it works, this due to a failure in the AMD libs (libatical*).
if i build the 0.24 successfully with gcc4.4 (atm you need 4.5, so every person would have to install additional libs so this isnt nice for a portable build!) and the mining works (may take a time, i only got a CPU to test on) then il release the 0.24 portable build. i will write a post when this is done

PS: excuse my spelling, im in a hurry

fixed for GCC 4.4. Thank you!

your welcome
EDIT: building + packaging = done.

pooler-minerd is marginally faster on all of my I7 and Core2 platforms ........for me anyways. Unfortunately, I don't have any AMD CPUs to test with.

[K1773R]

successfully built, enjoy

Haw You did it: "Support of BitForce devices"  ??

They wont show thier dev. They wont tell any1 when they will ship.
Haw You did it??

I have developed code for them by interface specifications. Remotely tested.

error in x64 fixed (when compiling in linux, dunno about winblows).

64-bit on Windows 7 enterprise without using the scrypt option (for bitcoin) does not see my cuda (nvidia graphics card) device.  32-bit version still works with the graphics processor.

Is the 64-bit version intended for scrypt mining only?

32-bit and 64-bit Windows versions have identical functionality.
Probably it can't find 64-bit nvcuda.dll on your computer.

sorry, i have no time to read 33 pages... )
tell me please how can i limit the consumption of PC resources so i could work with other programms while bitcoin-miner-64.exe is running?
current settings are

Code:

-a 4 -t 2 -v -o

and everything else is veeeery slow... thanks!

For me, officially the FASTEST Solidcoin Miner I am running (only tested x64 implementations thus far)......

My Dual I7 Xeon/Win7 x64 Based rigs have seen WELL OVER 5% increase in hashing performance running the latest Ufasoft x64 Miner, over Pooler's last release (pooler-cpuminer-win64-20120103).

Very nice work.

set the priority to below normal/low or dont use all cores (you got 2 as it looks).
you can creat a .bat file and put this in (right click it and select edit):

Code:

C:\WINDOWS\system32\cmd.exe /c start "ufasoft miner" /belownormal "C:\Documents and Settings\K1773R\Desktop\Downloads\bitcoin-miner.exe" -v -o http://K1773R_test:foobar@eu.eclipsemc.com:8337 -l yes

you dont have to set -t because its using the max cpu cores if you dont set it (see -help). the code up there should work, you just have to set the path to bitcoin-miner.exe and replace the pool (-o switch)
if the system is still lagging tomuch you change /belownormal to /low but the system wont be stable if you mine 100%, thats normaly for winblows!
just double click the bat file and it should work
