you can use exchanges as a online wallet i think, so in this situation you can use bittrex joincoin wallet

Which algo ?

Which algo ?

That was my first question. My second question is if the hashrate was from the miner or the pool. The miner
can report anything it wants.

Edit: third question, how much difference?


Here is more infos, sorry i wasn't accurate.

-= Algo =-

Cryptonight (XMR)

-= Software =-

cpuminer-opt 3.5.0 (compiled with CFLAGS="-O3 -march=native -Wall" CXXFLAGS="$CFLAGS -std=gnu++11" ./configure --with-curl)
minergate-cli 4.04

-= OS / CPU =-

Proshash
XMR-Mono : cpuminer -a cryptonight -o stratum+tcp://xmr.prohash.net:1111 -u xxx -p x

i tried both mono & dual mining, hash are near identical (more or less 0.5%)

-= Result =-

minergate-cli 4.04
reported miner hashrate : CPU1 - 67.8 H/s / CPU2 - 60.19 H/s
reported pool hashrate : CPU1 - 67.4 H/s / CPU2 - 59.88 H/s

cpuminer-opt 3.5.0
reported miner hashrate : CPU1 - 60.73 H/s / CPU2 - 55.80 H/s
reported pool (prohash) hashrate : CPU1 - 60.2 H/s / CPU2 - 55.3 H/s
reported minergate pool hashrate : CPU1 - 59.85 H/s / CPU2 - 55.1 H/s

so about 10% difference, i don't know what to think, if someone has similar experience. At first i thought minergate was favoring their own miner by showing advantageous hashrate in both the miner and the pool, but i get the same difference by using alternate miner on the minergate pool. That said with the low rates of minergate, i would probably earn more mining to another pool even with lower hashrate. But it just make me curious. They could also bullshit other alternative miners, reducing hashrate when alternative miner are used on their pool to force people using theirs, but i don't see what it would make them gain by doing that...

Looks like a clear difference. They likely bought a closed source miner and tied it to their pool.

Edit: try playing with the thread count. 4 threads is usually better. The formula for the optimum thread count is
(L3 cache size / 2MB). An i7 and your xeon have 8MB L3.

you can use exchanges as a online wallet i think, so in this situation you can use bittrex joincoin wallet

It doesn't look that way to me. They give me a key that maps to an address where the mined coins go.
I need to import that key into a wallet to get access to the address and the coins in it.

If you can exlain how to do that without installing the wallet let me know.

I don't know why their messing with keys when most other no-login pools simply use the address directly.
It makes me suspicious, private keys are not meant to be exchanged.

Edit: Nevermind. Elsewhere it says it accepts an address as the user. I don't have an account at bittrex yet
but it's better than installing a wallet.

edit: First test of bastion on i7-6700K gets 184 kH/s vs 169. Will look for more.

A couple more observations, your xeon doesn't support AES so that  will slow it down and your atom only has 4MB of cache.
Neither are good choices for mining.

I found a pretty good workaround for the problem of git deleting empty directories.
Any dummy file will do but I like the recommended .gitignore solution.

http://stackoverflow.com/questions/115983/how-can-i-add-an-empty-directory-to-a-git-repository.

I managed to get bastion to 185 kH/s on my i7-6700K but that is probably it.

Oh yes definitly they're not worth mining, but they allow me to learn, and they cost me nothing to make run (i don't pay anything for them). I was just surprised @ the difference of hashing, but you may be right it's probably a private miner (possibly to bring them botnet hashing power since it seems to be the most efficient linux based cpu miner). I tested different threads combination but it's not improving things. Less thread or more threads give about the same difference.

Oh righhttt forgot about this one, ah well been a few years i used github ^^;; good you found an elegant solution  Cool

Is there a list of which of the algorithms use AVX and/or AVX2 on supported CPU's? The original post and readme say about 20 of the 40 support AVX2 but I can't find a list.

I'm mining XMR here, and I see the cryptonight algo doesn't support AVX. I assume it would be better if I mined a coin which has an algo which does take advantage of AVX instructions?

I haven't made a list. You shouldn't choose an algo simply based on whether the algo has certain features. Choose it because
it's more profitable than other algos regardless of the features. Some algos are resistant to parallelism but it doesn't mean they
aren't as profitable as those that aren't.

Edit: Let me rewrite the last sentence from the opposite perspective. Some algos are able to use AVX but it doesn't necessarily
make them more profitable than those that are resistant.

In addition GPUs are better at parallelism so any algo that can be parallelized is dominated by GPUs or ASICs. The only real
advantage a CPU has is HW AES support. GPUs don't have it therefore any algo that uses a lot of AES has a natural advantage
on a CPU. Cryptonight is an example of an algo that uses a lot of AES.

Many newer algos have been designed to require high memory bandwidth. This creates challenges for both CPUs and GPUs
beyond their compute capability. Optimizing the compute performance won't improve the hash rate if the memory system
is already bottlenecked. That's what happened when I optimized zcoin for AVX2. Even before optimizing it maxed out with
only 3 CPU threads due to the memory load.

algo/hodl/hodl.cpp:96:18: error: aggregate ‘EVP_CIPHER_CTX ctx’ has incomplete type and cannot be defined
   EVP_CIPHER_CTX ctx;
                  ^~~

It looks like a problem with an included library, <openssl/evp.h> to be specific. Probably a missing package.

How old is your CPU? It needs to be 64 bit.

Strange...
After successful pull from git, make clean and make distclean, the binary still says v3.5.0, not v3.5.1

The configure file doesn't get deleted by make distclean but does get deleted by git. As a result the version
change was lost when I uploaded to git. I should have made the change in configure.ac instead of configure.
Had git been aligned with "make distclean" I would have discovered the error.


Edit: try it now I just pushed a fix for configure.ac
