[ANN][AR2] Argon2Coin new PoW algo, CPU friendly

[ocminer]

Pool:
https://ar2.suprnova.cc

The CPU-Miner needs a patch for pooled mining, i've included it here:
https://github.com/ocminer/cpuminer-multi-1

thanks, oc

Thanks ocminer.
New release of cpuminer now is on github.
https://github.com/Encel-US/cpuminer-multi
windows x64 binary https://github.com/Encel-US/cpuminer-multi/releases/tag/cpumine-v.1.2

So, Welcome to first Argon2 pool
https://ar2.suprnova.cc

Can you put the pools source on github ?

We would like to add a pool too.

Yes, let me fix up hashrate calcs, estimates etc and I'll push it to github then.

Weird issue I am having.

The miner works on my AMD 8350 and AMD 1100t but it will not run on my Intel 4790k. I have pause set in my bat and it stops when I start the miner on the Intel cpu but there is no error message. All 3 machines are on Windows 7 64bit and the only thing different on the 3 is the Nvidia driver. All bats are exactly the same.

Which miner u using ?
I have also AMD 8350 and hashing 240 H/s

The latest that Encel-US just posted in post# 186. The first version does the same though.

I moved to win 7 and no change. what can be wrong since we have the same CPU ?
We have the same cpu and os (win7) but I"m hasing 10-15 time less.
Oc you are an expert what can I do wrong ?

maybe performance/power settings in Windows or BIOS ?  maybe try to somehow set it to full performance. and not some strange power saving feature which limits performance?

on my older laptop (AMD A-8 4500M) i get slow hashrate with miner, and about 2kH/s with wallet's setgenerate
wish i could mine on the pool with this laptop...

Found it . Just disable kaspersky and my hashrate jump from 240 H/s to 2200 H/s
I had always kaspersky running when mining and that is first time for me

@ocminer your pool retargets too high:

and then no shares for 20 minutes...

Hmm this is actually quite weird .. Never saw a miner > Diff 4 until now.. Whats your CPU ?

Hashrate calculations should match up now for everyone else

using 3 VPS total ~2kH/s
used same worker for all, now trying to switch to 3 workers
wish that cpuminer will be fixed for AMD so i could mine with laptop too

Added reward for translation into other languages - 200 AR2.

Good news. Argon2Coin is on the exchange

Here is BTC and USD trading pairs:

https://c-cex.com/?p=ar2-btc
https://c-cex.com/?p=ar2-usd

Also it is tradable to LTC and DOGE:

Premine is now 1/3d of coin supply. Hm.

After unsuccesfull tries to compile the miner in VC2013, I tried using msys64, but it always fails with this error:

Code:

/usr/lib/gcc/x86_64-pc-msys/4.9.2/../../../../x86_64-pc-msys/bin/ld: cannot find -lpthreadGC2

configure does not show any errors. any ideas?

seems compiler doesn't see pthread libraries
p.s. try this pthread

already tried that pthread archive and copied the x64 content to my bin/lib/include directories, but still the same error.

in vs 2013 the compile is breaking here. Any sugestions?

i dont fix miner to build with vs2013, try this for vc2013 https://github.com/tpruvot/cpuminer-argon2.git

ah, much better! thanks!

i lied, it compiles, but gets share above target errors, and is terribly slow ugh lol
