An (even more) optimized version of cpuminer (pooler's cpuminer, CPU-only)

[Minor]

I'm having trouble compiling under 64-bit Slackware Linux 13.37
In an empty directory I did:
git init
git pull https://github.com/pooler/cpuminer

When I run ./autogen.sh
I get the following warning and error:

/usr/share/aclocal/imlib.m4:9: warning: underquoted definition of AM_PATH_IMLIB
/usr/share/aclocal/imlib.m4:9:   run info '(automake)Extending aclocal'
/usr/share/aclocal/imlib.m4:9:   or see http://sources.redhat.com/automake/automake.html#Extending-aclocal
configure.ac:15: installing `./compile'
configure.ac:4: installing `./config.guess'
configure.ac:4: installing `./config.sub'
configure.ac:6: installing `./install-sh'
configure.ac:6: installing `./missing'
compat/jansson/Makefile.am: installing `./depcomp'
Makefile.am: installing `./INSTALL'
configure.ac:61: error: possibly undefined macro: AC_MSG_ERROR
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

./configure then fails with:
...
...
checking for pkg-config... /usr/bin/pkg-config
checking pkg-config is at least version 0.9.0... yes
./configure: line 5102: syntax error near unexpected token `,'
./configure: line 5102: `LIBCURL_CHECK_CONFIG(, 7.10.1, ,'

I managed to get rid of the "underquoted" warning by adding [] quotes in a few .m4 file in /usr/share/aclocal, but I don't know what to do about the "undefined macro: AC_MSG_ERROR" error and I still get a broken ./configure
Any help would be appreciated.

OK, I copied a random libcurl.m4 (https://gnunet.org/svn/libmicrohttpd/m4/libcurl.m4) to /usr/share/aclocal and started over.
I got a bunch of new warnings when running ./autogen.sh, but the ./configure it generated seems sane and make made me a minerd that at least works with the --help option...

Amazing job! But I have a problem with 64-bit version on Windows XP x64 and dual Xeon E5310. The error message is: "Entry point not found. The procedure entry point kernel32.IdnToAscii could not be located in the dynamic link library Normaliz.dll". 32-bit binaries run well. Any hints?

32bit windows binary is ready but i think not many ppl may want it.
mingw64 is not easy to play with...…

[mrx]

decided to put it online. Windows 32-bit version has a little improvement.

Before 11khash/s
Now 16khash/s

[mrx]

New windows binaries (both 32-bit and 64-bit) uploaded to github. Please test them, especially 64-bit one. Don't know if it's working fine.

Tried the 64bit version, doesn't work, windows tell me about impossible starting the application in 0xc000007b

The 32bit one work, 16khash/s

same to me...

64 bit error

[mrx]

sorry for last few 64bit binaries. I've uploaded a new pack which can be found at github. Or the direct link:

https://github.com/downloads/RuxiaoMa/cpuminer/cpuminer-win64-31c3074-testing3.zip

If it won't start because of 0xc000007b, a report of Dependency Walker should help a lot.

Thanks!

[Gabi]

It work

And wow, it does 21.6khash/s

So:
old miner: 11khash/s
your latest 32bit one: 16.1khash/s
and the 64bit: 21.6khash/s

All on a Q9550 at 2.83ghz

great work with that new win64-cpu-miner:

"old" 64-version: i7 2600k / 4.6 GHz / 7 threads / 35 kh/s (pooler-cpuminer-win64-20111221.zip)
"new" 64-version: i7 2600k / 4.6 GHz / 7 threads / 43 kh/s (cpuminer-win64-31c3074-testing3.zip)

it's running fine now, thx for excellent work

heh, this stuff is tough to keep up with. 

You said it!

Alright people, new version out! This should bring a little more speedup to almost all CPU's... including AMD ones!

I finally managed to get some decent speed increase (+38% over the previous version) on my Phenom II, and this seems to apply to all processors of the K10 family, including newer Semprons.
Unfortunately you won't notice any additional speedup on older K8's, like Athlon 64's.
I haven't been able to test this version on newer AMD microarchitectures such as Bulldozer or Bobcat, so feedback from FX/Fusion owners will be greatly appreciated.

Diki is now back from his vacation, and was kind enough to provide new binaries for Windows. Here they are:

my 2x xeon (ok not mine) now reach nearly 48kh/s! however my phenomII X4 940 doesn't get so much improvements. maybe because of the overheat problem of my cpu?

[michaelmclees]

Enormous increase!  Wonderful work again!

OK, here is an odd-ball request, I thought that I saw a version that was compiled for a PowerPC G5, but now I can't seem to find it. I have access to a couple PowerMac G5s (one MacOS X version unknown) and one with Linux, distro and version unknown.

Edit: Seems Ubuntu 11.10 can run on the PowerPC G5, so I'm going to try to run off a USB key. If I can get them running I'll update this post.

Edit 2: Here is the thread I wanted: https://bitcointalk.org/index.php?topic=55953.0

Any updates after this will be there.

Thanks,

Wow
With the new 64bit: 22.5khash/s

EDIT:  Nevermind, fixed it!
