Hi all

Juste a question, i have both AES-NI and no AES-NI cpu with windows 7 x64. Can i use only you last build minerd-wolf-07-09-14.exe for both cpu , or i have to choose the AES version cpuminer-multi-wolf-06-09-2014.zip for my AES cpu ?

don't know it you last version can support both and detect AES cpu.

And if someone have an idea of how to detect a aes-ni capable cpu from a script (wmi , vbs).

Great job !

just wanted to say that if you run on a single core cpu, by default it does nothing:

0 miner threads started, using 'cryptonight' algorithm

1 - 1 = 0 :-D

Oops. I should fix that.

EDIT: Pushed fix.

minerd-wolf-07-09-14 hits me hard with a decrease in performance. ~120 h/s

using minerd from cpuminer-multi-wolf-06-09-2014.zip ~190 h/s

CPU is a 12 core Xeon E5-2430 V2 Is this expected?

are you sure you are using the same number of threads in both cases?

I think that minerd-wolf-07-09-14 is only for non-AES-NI cpus. That would explain the drop in hashrate for you and why when I tried it at first I saw a major drop in speed.

Win64 binaries exist but require AES-NI.
If I compile from source should I be able to run it on a processor without AES-NI then?  I compiled it successfully in an Virtualbox Ubuntu 13.04 virtual machine (on a Win 7 host without AES-NI), but get:

Code:
[2014-05-31 09:46:38] Using JSON-RPC 2.0
[2014-05-31 09:46:38] 2 miner threads started, using 'cryptonight' algorithm.
Illegal instruction (core dumped)

upon starting up the miner.

Configure with --disable-aes-ni

Whereabouts do I need to put the "--disable-aes-ni" when compiling?

make -j<numberofcores>

possibly "make clean" before "make"

Similar results here. I ran some tests with a dual E5520 server.

cpu-multi / LucasJones (these are the same thing, right?) v2.3.3 gets max 148 H/s and is pretty much always over 140.

Wolf's newly provided non-AES version gets 118 H/s max, with a range of 100 - 118.

Looks like any advantages of Wolf's miner come from the AES-NI code.

I've now complied and run Wolf's latest version on this same non-AES-NI machine under Linux and although there's a very slight improvement over windows it's still way slower than LucasJones' is under Windows.

So I can only assume my previous statement was correct and that any gains Wolf's version gives are down to the AES-NI parts of his code and you need a machine with AES-NI capable cpus to take full advantage of it.

Thanks, guess I had a hard time reading lol. It clearly stated that it was for NON AES-NI. Not sure what I was thinking. THanks again.

I get this error when i try to compile it:

Code:
root@prox8:~/cpuminer-multi# ./autogen.sh
configure.ac:133: error: possibly undefined macro: AC_MSG_ERROR
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.

How to solve that?

minergate has 32 bit miner but they restrict the pool  Cry Cry

Plus, it's Minergate Tongue

Anyway, 99% of demand for 32-bit miners are botnets - if they want to make asstons of money, it ain't gonna be free.

Hey..

Firstly, thank you for the awesome CPUMiner. It works like a charm.

Is merged mining possible with your / Wof's CPUMiner?

http://bitcoin.stackexchange.com/questions/273/how-does-merged-mining-work
http://monetaverde.org/

Merged mining will allow you to mine MCN (MonetaVerde) in addition to to the major coin (XMR etc) without a reduction in hashrate.
I see its been asked before, but i was unable to find a conclusive response.

Cami

Btw.. Just thought i'd mention this:

Latest CPUMiner compiled from git: (24 x Intel(R) Xeon(R) CPU X5650 @ 2.67GHz)

Over a 20 minute duration:

[2014-08-02 20:25:25] accepted: 191/234 (81.62%), 230.74 H/s at diff 980 (yay!!!)
[2014-08-02 20:25:29] accepted: 192/235 (81.70%), 230.63 H/s at diff 980 (yay!!!)
[2014-08-02 20:25:29] accepted: 193/236 (81.78%), 230.61 H/s at diff 980 (yay!!!)
[2014-08-02 20:25:31] accepted: 194/237 (81.86%), 230.16 H/s at diff 980 (yay!!!)
[2014-08-02 20:25:40] accepted: 195/238 (81.93%), 231.01 H/s at diff 980 (yay!!!)

Then i removed all of the "optimizations" from the Makefile:

From:

am__append_3 = -Ofast -flto -fuse-linker-plugin -funroll-loops -fvariable-expansion-in-unroller -ftree-loop-if-convert-stores -fmerg
e-all-constants -fbranch-target-load-optimize2 -fsched2-use-superblocks -maes

to :

am__append_3 = -maes

The result?

There are numerous posts/warnings on-line about over-aggressive compile-time "optimizations".
Just thought I'd post my results/findings which concur.

Each optimization I tested worked on my CPU - I don't have all CPUs, so I can't test. That much of a reduction is odd, though... are you sure the test wasn't affected by other factors?

It's quite a difference. I have 8 of those monster servers that are freshly installed (+updated) with Ubuntu 14.04.
They are all identical and unused (no running services, crons etc..) but the results are rather inconsistent across each so perhaps something else could be influencing things.
I'll dig a bit deeper and see if anything comes of it.

One thing I found rather interesting:

root@cami001:/# minerd --help
..
  -t, --threads=N       number of miner threads (default: number of processors)
..

root@cami001:/# grep processor /proc/cpuinfo | wc -l                     
24

root@cami001:/# /usr/local/bin/minerd -o stratum+tcp://x.x.x.x:x -p x -u xx
[2014-08-02 15:49:42] Using JSON-RPC 2.0
[2014-08-02 15:49:42] 31 miner threads started, using 'cryptonight' algorithm.
[2014-08-02 15:49:42] Starting Stratum on stratum+tcp://x.x.x.x:x

Out of interests sake, how/where is 31 processors being returned? If I set the thread count manually (-t 24), 24 threads are used and the H/S is extremely consistent.
