nice i opened 8 instances and having same khash like joelao v2 on all 8 threads together on 4790k, but when i open only 3 instances of 8 improvment is huge 23 khash to 15 khash per thread maybe you can do something so hashing stays same with more threads instances

You will get a higher hashrate per thread when the CPU is not fully loaded, no matter what I do with the compiler. You will get maximum possible total hashrate when the total number of threads running is equal to the number of CPU cores on the machine.

Having problems with the Windows 64 bit miner I published? Too slow? This is due to the limitations of the compiler used.

This is an old problem which will go away once I have compiled the miner using Msys/Mingw64 instead.

Instead of running a single instance of minerd with multiple threads, run multiple instances of minerd with single threads (which is what my autominer does for you). You will see a major improvement.

On Intel CPUs I get better results, but with AMD worst..hmmmm strange :/
On AMD (8 core FX8320) is always ~50% CPU usage (doesn't matter if I mine with -t 2 or -t 7)

try this one download few and test, best for me was generic one with 4,8 overclock 8320 is just a little slower than 4790k at 4,4  Wink and say thanks to wolf0 and joelao95

try t6 if youre working on pc while mining you should have 70 to 80 khashs and with t8 around 100

Thanks, that helped!
But I still have problems with clock droping - do you have some tip how to solve this?
It looks mine CPU cooler is not doing jobe well, so clock keeps droping when temp is high.
I tried everythind, disabled lot of things in BIOS but nothing helps.
If I overclock it, it only gets worse, so I'm running not overclocked at regular 3,5 and getting 65~58 khash with my AMD 8320.

what is your temps and cooler is it stock and whats your mobo.
if you have below 62 c its fine, 990 fx sockets runs very hot if you watercooling or have stock cooler you should put one fan to blow directly to mobo socket.
your cpu is downclocking bc cool n quiet is turn on in bios, you should turn off all power saving options in bios to prevent downclocking especialy if you oceing but only if your temps are below 62.
measure your temps with hw info and disable ai suite if you have asus mobo and report back all temps core, socket, nb, sb, etc so i can help you more corectly.
if your cpu is on air you should aim at 4,4 overclock with 8320 with no overvoltage or very little. if you have good cooler and and temps below 62 your settings should look like this

Ai Overclock Tuner - Manual
AMD Turbo CORE Technology - Disabled
DRAM 1600Mhz @ 1.5v or your ram settings
CPU Frequency  - 4400Mhz
CPU/NB Frequency - 2200Mhz
HT Link Speed - 2600Mhz
CPU & NB Voltage - Manual Mode
CPU/NB Manual Voltage - 1.25v you can go to 1.30 but only if you have sufficient cooler and stability issues
CPU LLC - Ultra High (75%)
CPU/NB LLC - Auto
Cool'n'Quiet - Disabled
C1E - Disabled
SVM - Disabled
Core C6 State - Disabled
Amp Master Mode - Disabled

try this only if you have stability issues

CPU Current Capability - 130%
CPU/NB Current Capability - 130%
DRAM Current Capability 130%

does this support http yet?

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

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%!!

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?

Pretty much none are *critical*, however, omitting an optimization flag will cause autoconf's default -O2  option to take effect, because for some reason it forces that on people's code.

Sure I do. As you have a lot of work, I'm gonna start to develop a first demo soon.

64 Bit version is still slower at only 3.2K per thread on my AMD , where as generic one is 4.5K a thread mine is the same its not using all cores to 100% some are not even used at all

maybe something else is using your cpu thats to low, usage should be at 100%, even 1055t have 10.55k per core/thread with generic v2 from joelao95, do you mine with gpu some other coin at the same time bc ccminer can use 15 % of vishera cpu per 1 gpu  

No you miss understood , using - t 8 on mine with nothing else running, its not using ALL cores , 5 of my cores sit at zero and 3 at 100%

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%!!




If it core dumped, it's a bug - possibly on my part. I test with -Ofast - I know what it does, and I know it's dangerous because it enables behavior that violated the standards.

Coin of the Magi!
Dev,any development plan in 2015?

Any development plan?
Although I'm not the dev, I will answer it (he'll be online in a few hours).

Please check the OP for more details, search for Timeline.
Our standalone payment gateway is currently in beta-testing and will be launched soon. With it, we are independent of any payment processors and allow merchants to accept payments in XMG.

...

Furthermore, we're planning a marketplace where people can sell their items and get paid in XMG. Electrum and Android app, donation plugins and P2Pool are more ideas.

If you have ideas, let us know. We appreciate any community input.


Thanks for the details mate. The timeline is basically the plan, however I will put particular emphasis on the magipay and the marketplace. You still remember the marketplace I discussed with you long time ago.  Smiley

8350 4,5 t8 max 105 khash

4790k 4,4 t8 max 120 khash
Not to forget the AMD is much cheaper:

FX-8350: 155€
i7-4790k: 300€

@wolf0 and joelao95: Any chance the new miners can run on ARM?  Cheesy

A Proof-Of-Donation Dogeparty Asset has been created. It will be distributed after POD phase is complete.
Mined funds will be sent directly to the XMG dev's donation address. Dividends will be paid out on the asset! (% TBA.)

Then your toolchain is shit and doesn't have the optimizations - you can update it or remove the flags -flto and -fuse-linker-plugin.
