Try "make distclean", then "AR=gcc-ar RANLIB=gcc-ranlib ./configure", then "make".
Work. Thanks.

Windows 32 bit miner

Compiled using vanilla Cygwin32 with my custom tweaks. Its ... er ... fast. Did my head in Cheesy

https://www.dropbox.com/s/dgridplxdegxf1h/Spexx-Wolf0-V2-Win32-XMGminerd.zip


thanks! my hashrate increased from just khs to 4.5khs Cheesy (old core2 cpu)

My hashrate also was improved. Thank you!

Now I wish I had higher price on market. More to trade, more to buy :-)

Optimized miner [V2]:

https://github.com/magi-project/wolf-m7m-cpuminer-V2

Credits should go to Wolf0. This optimization is done based on his optimized miner https://github.com/wolf9466/wolf-m7m-cpuminer, by further abstraction of the gmp computation according to his prior work, as well as a few other improvements have been carried out. Anyone who can achieve further optimization and boost the speed, please release the code accordingly.  

The above miner is slightly different from that on which prior windows compilation is based; so the speed might be different (not much expected). I will get another set of compilation for Windows.

The following is the miner with "-e" option in order to adjust CPU usage.

https://github.com/magi-project/m-cpuminer-legacy-v2

Code:
minerdlegacy -o stratum+tcp://pool_url:pool_port -u pool_user.worker -p password -t thread_numbers -e cpu_efficiency



Great work again Wolf0 and Joe,

However, the new minerd core dumped in my Xubuntu 12.04 box running on an Athlon 64 bit cpu.
I have never liked the -Ofast compiler option, so I removed it from the makefiles.  Then I ran make clean and reran
make and after that the new minerd runs fine.  Speed increase from 5.03 KHash/s -> 7.23 KHash/s.  43%!!



Fellow miners, get your thens and thans in order and help other forum readers understand what you are writing. Remember the grammar basics:  B larger THAN A (comparator operator). If something THEN ....

Yes, it does as I tested once, please test it and let me know any issues.

make and after that the new minerd runs fine.  Speed increase from 5.03 KHash/s -> 7.23 KHash/s.  43%!!

I totally have no idea about those compiler flags, nor I had enough time to research & test. I simply copy those flags from makefile.am in Wolf's version and replace the original ones. Wolf, can you specify how / in what situations we should make use of them, and which of them are critical?

I got another 10% speed improvement on my Has(h)well I5 box by tweaking the already excellent mods done by Wolf/Joe .
From 72 KHash/s to 81 KHash/s  Shocked   running 4 threads on my i5-4460 , no overclock

This tweak/hack uses a different implementation of the sha256 function and will only work on chips with AESNI/AVX2 .
Here is how I did it.  Read on if you are interested (Warning: The below will be a bit technical and applies to Linux only):

So I copied the source code from http://lxr.free-electrons.com/source/arch/x86/crypto/sha256-avx2-asm.S.
The code in here replaces the sha2_round code found in the m7/sha2.c file.
I edited it carefully by removing the line numbers and commented out the following lines
// #ifdef CONFIG_AS_AVX2
// #include <linux/linkage.h>
..
.global sha256_transform_rorx  ## ENTRY(sha256_transform_rorx)
..
//  ENDPROC(sha256_transform_rorx)
and the bottom line
// endif
Then stored the resulting as sha256_rorx.S in the m7 subfolder of the miner source.
Then edited the m7/sha2.c as follows:

// Added this line above the below C function:
extern void sha256_transform_rorx(const void *input_data, sph_u32 *digest, unsigned long num_blks);

// Then the following changes to this function.
static void
sha2_round(const unsigned char *data, sph_u32 r[8])
{
// Comment out these 3 lines
//#define SHA2_IN(x)   sph_dec32be_aligned(data + (4 * (x)))
//        SHA2_ROUND_BODY(SHA2_IN, r);
//#undef SHA2_IN
// Add this line:
   sha256_transform_rorx(data, r, 1);
}

saved the above file, then ran the following commands:
run 'make' in the m7 folder.
Then run 'gcc -c  sha256_rorx.S'
Then 'cd ..'
Then:
gcc -std=gnu99  -O2 -pthread -fuse-linker-plugin   -o minerd minerd-cpu-miner.o minerd-util.o minerd-sha2-old.o minerd-scrypt.o minerd-m7mhash.o minerd-haval.o minerd-keccak.o minerd-ripemd.o minerd-sha2.o minerd-sha2big.o minerd-tiger.o minerd-whirlpool.o m7/sha256_rorx.o -ljansson -lpthread  -lgmp -lcurl -lm

There are other versions of the above, so for example you might try the sse3 version if you only have a core 2 duo, for example.

Damn much respect!...... I have an old CoreDuo doing 5.32!!!! an I5 pumping out 25.80 and various New 2 core Celerons pumping out 4-5kh..

You guys took my CPUs to another level.

Any recommendations for a nice CPU without breaking the bank? I assume i7 but which ones?

Yesterday, I bought an i7-5930k, an ASRock X99 WS, 32GB of DDR4 at 2666Mhz, and a liquid cooler for the CPU with BTC at Newegg - she's gonna be my new main system. I'm pretty sure that should hash well.

Looks like you are building for the future Grin
If I were to build a similar system in my country (Norway), I would have had to fork out the equivalent of $1759USD for those parts, plus
a bit for a cooler on top of that.
An i7-5930K alone costs $700 over here.
A more modest i7-4790K costs $400.
Anyways, If one is looking to buy new gear, the only game in town for serious CPU mining seems be Has(h)well-based chips,
from any I5 and upwards.

Try "make distclean", then "AR=gcc-ar RANLIB=gcc-ranlib ./configure", then "make".

Tnx, solved my problem too Smiley

Well then... my Windows laptop used to dish out about 25Khash/s, and I had some virtual pcs on free trials, coming together at about 75-80Khash/s according to the suprnova pool. With the recent development and optimizations by spexx and Wolf0, the total adds up to...

Wait for it...


220Khash/s Cheesy

Yup, 220 is not an error, It's been stable like that ever since I upgraded.

I'd say the boys should post some XMG addresses. Even if the speed boost does effect the network negatively a bit, these guys are working hard and this stuff isn't easy. I know I'll donate, even if it isn't a fortune Cheesy
On a separate note, Joe also deserves some kind of reward, working on pretty much everything else XMG related Wink

I'm a lazy ass low class user interface programmer, so I'll kindly ask all three of you to post your XMG addresses again, because the 90 second search limit on this thread is killing me - and I'll send over a bit of what I've mined so far Smiley I'm willing to bet I'm not the only one grateful for all the great work you're doing either Cheesy Anyway, keep it up!
