it seems to be slower than minerd, anyone confirm? 6khash compared to 10 khash (minerd)
Please tell me what CPU/number of threads?
I think pooler-cpuminer is optimized for AMD.
On Intel Core 2 results are more similar.

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

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 Wink

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 Smiley 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 Smiley

PS: excuse my spelling, im in a hurry Wink

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.

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.
