Topic: [XMG] M7M CPU mining discussion thread - page 5. (Read 35631 times)

If you like the concept of Magi and would like to make more profit, I'd appreciate if you don't sell it to miners with big hashrate. Doubling low miners like my 5-8 kh/s wouldn't be a problem for Magi 

As you usually want to make profit, I hope you support our way and make your profit with mining.

Not bad. What is the usual hashrate for this CPU? Did you start selling your optimized miner or will you keep it privately?

The long-term goal of Magi is to achieve, that the majority of miners are simple home computers, Raspi's or similar ones like the one in your link.

Odroid XU3-Lite http://www.hardkernel.com/main/products/prdt_info.php?g_code=G141351880955

Samsung Exynos5422 Cortex™-A15 1.8Ghz quad core and Cortex™-A7 quad core CPUs

~10kH/s

 

Not bad for 10 Watt.  

edit: I must correct myself, it does "only" 7.66kH/s. The 4 big cores showed the hashrate (1.28kH/s each) way quicker than the 4 little cores (0.63kH/s each). Still quite impressive I think.  

Wolf, you're welcome to do so; also I'll welcome GPU if anybody could do. Well, I don't want to freak out all CPU miners because of this possibility or possible existing GPU miners already.

People mining XMG should take a look at it's block reward design. Don't mine too hard, or PoW blocks will stop yielding coins (block chain still going). Different people have different understanding though, check out the paper (need update upon the coming hardfork, but the same concept applies).

http://arxiv.org/abs/1409.7948

The reward is designed best at the CPU mining level. Anyone fire up CPU farm or GPU may push reward towards a trivial level. The coming hard fork will tailor the reward at a much accurate level.

Remember, the more CPU miners (not too high hashrate though), the more secure of the reward. The more GPU miners (let's say in the future and assuming they have significantly high hashrate), no actual rewards will be yielded.  

Please remember to update your wallet above v1.2.0:

p.s., I am actually keen to see how magi's block reward design could cut down ASIC miners in a scrypt coin.

Due to free electricity/botnets I don't think this has existed for some time.  I've searched a lot and about the best I've found came to around 30% less than I needed to break even with 0.14 kwh electricity.
They are changing how hash rate affects payout for M7M it seems however, so maybe it will be one of the first to fix this.

Anybody actually making a profit in cpu mining? If so, please impart your wisdom and coin choice upon me

I don't know - mine was slightly modified, as I said before.

Xmg still at the top of charts in mining
 

Thanks, Spexx!

No idea; my 4770k does 43kh/s at 4.5Ghz

If you are compiling the miner for Linux, the compiler will create avx and/or avx2 compatible code if you include the string  -march=native in the CFLAGS.

If your operating system is 64 bit Windows, then to support avx and avx2 instruction sets you need Windows version 7 SP1 minimum.

My miner software package for Windows includes four versions of the miner: 32 bit, generic, avx and avx2. The software selects the correct miner for you automatically.

https://bitcointalksearch.org/topic/m.9412187

Generally speaking, the avx version is about 1 percent faster than the generic version, while the avx2 version is almost 4 percent faster.

Happy hashing

Hi guys,

Which miner is best for an AVX CPU and AVX 2 cpu? Thanks.

Now doing solidly above 30, it's an i7-4700HQ.

Missed a few posts before.

Firstly, repost the hard fork as already mentioned by jawitech.


Please update the wallet to v1.2.0.1 (mandatory):

Windows: http://coinmagi.org/files/magi-release/win32_magi_v1.2.0.1.zip
Linux: http://coinmagi.org/files/magi-release/linux_amd64_magi-qt_v1.2.0.1
Source code: https://github.com/magi-project/magi/

This update includes the following hard forks:
PoS hard fork at block 131100 for better staking results (Expected on January 6)
PoS-II Protocol V2 hard fork at block 131300 (Expected on January 6)
PoW-V2 hard fork: 1/7/2015, 12:00:00 PM EST time (GMT-5:00)

I did spend some time and tried to figure out the CPU algo, but all have been done just under the range of my knowledge. People are talent; no one would know the capability other people can do. It's not my intention to hold firmly the CPU algo statement. PTS was arguing only CPU minable, and was awarding how many dollars for a GPU miner? Everyone knows that PTS is minable with GPU now.

Once upon a time, someone was suggesting me that, go for a CPU algo, finish the PoW mining and then going into PoS. That was right likely, but not all to me. Pure PoS is not right way I figured.

Wolf0, you're absolutely right (not the GPU part since not proved yet), that "just because no one bothers to spend the time on it" cause it's unprofitable. Let me extend the statement, the idea of GPU mining is neither profitable for now, nor profitable in the future even when magi gets into top. I encourage people to work on a GPU miner for magi, but surely up to you whenever you see a time coming with profits.

Wondering?... read the OP, or the coinssource article, evok3d did spend a lot time researching and writing before publishing the article:
http://www.coinssource.com/coin-magi-a-cpu-miners-dream-proof-of-mining-pos-ii/
I've spent time on this, and the idea behind it worth of a try; I want to say magi is a coin CPU minable "ever".

I almost forgot to post the miner, for some people who may want to run it in computers with limitations, just use the "-e" option.

# m-cpuminer-legacy

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


This is none different from the regular miner, except that an option "-e cpu_efficiency" is added, where cpu_efficiency is a number between 1 - 100, for example, 50 representing for 50% of CPU usage. A few instances:

Magi hardfork, please update your wallet and have a look at the improvements

My laptop does 29 - 30kh/s with 4T, slightly modified cpuminer.

Probably could do better then , but I have another 30 opened aps on my PC when tested it. The temp was constant about 80-83 degrees (Celsius) with average air-cooler CM Evo212...

Yes, I have the know how, but it's not worth it to write a GPU miner right now. Not that it won't perform well - the algo should suit GPU fine - but it's a lot of work to make.

The max I gained with my 4790k at 4.6GH was about 40...
EDIT: Which is the temperature of HQ4700 when you load it ?
