Finally got the yenten-1.2.1 GUI wallet to work in Ubuntu 16.04.03 64bit



Build yentend 1.2.1 and GUI on Ubuntu 16.04.03

Finally got my Odroid XU3 lite mining by compiling yentend, wasn't able to compile cpuminer-opt. Is the source of minerd available somewhere?
Mining on 7 of 8 cores at 93°C, Hashrate reports vary wildly: most often it's around 63 but rarely it's reported as 0 or up to 140, probably some kind of lag. Not too bad for an ARM CPU (Exynos 5422), OS is Debian Wheezy. My properly cooled and slightly overclocked FX 8320E does 650 hashes per second btw.

Had to configure with --ignore-incompatible-bdb and remove a "-msse41" from yescrypt.h in src/hash/yescrypt. More could be possible with some ARM optimization and compile option tuning, my only CXXFLAG was O3.

Too bad the hashrate almost doubled today.

Looks awesome.. But I have a question 2.9 cpu x32 what is that mean ? Kind of Amazon aws or something?

No, just two Xeon E5-2667 V3 cpu's.
8 cores each with hyperthreading so 32 total.

[eule]

Poser. 

[Xeon_Xeon]

Poser.  

Nope, all go no show.

Just be glad all my other dual Xeon boxes are mining other coins......at least for now.


Trying pool mining now.

./cpuminer -a yescryptr16 -t 32 -o stratum+tcp://pool.bilbotel.fr:6234 -u Yxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx -p c=YTN

I get about %50 invalid shares if I use all 32 threads but if I use 30 threads it drops to %25  

The fewer threads the lower the invalid shares but lower hash rates.

Trying only 16 threads fo a while.

EDIT:  I forgot I was already mining Sumokoin on all 32 threads. LOLOLOLOLOLOLOLOLOLOLO 


Fired up 32 threads again to see what happen now.

You could try disabling Hyperthreading in the BIOS and run with 16 "full" threads. Better than losing so many invalid shares or running at half power imo.
LOL indeed.

So you are on which pool now.

[zzwensel11]

Bitzeny goes up. Difficulty increases. Some miners peel off to yenten mining.

Hold onto your hats.

Still hope this coin will stay under the radar for quit some time. Mining is still easy :-)

I would expect that the Yenten price is going to follow Bitzeny at a certain moment. Anyway wonder why the old lady (Bitzeny) is suddenly rising so fast.

I would expect that the Yenten price is going to follow Bitzeny at a certain moment. Anyway wonder why the old lady (Bitzeny) is suddenly rising so fast.

I had the same thoughts. Bitzeny's main exchange has crashed so many times. Reminds me of cryptopia few months ago.

Yes very good, what is your processor?

intel core i7-2860QM from some years ago

So far so good!

So you are on which pool now.

It just does, I did not do anything special.

Downloaded the source and compiled then ran the miner, no tweaks or anything and just used build.sh then make then ran it. So thats a question for the dev.

Only one invalid share overnight.

Now to solomine with 16 threads at the same time I pool mine to see what happens.

Finally got my Odroid XU3 lite mining by compiling yentend, wasn't able to compile cpuminer-opt. Is the source of minerd available somewhere?
Mining on 7 of 8 cores at 93°C, Hashrate reports vary wildly: most often it's around 63 but rarely it's reported as 0 or up to 140, probably some kind of lag. Not too bad for an ARM CPU (Exynos 5422), OS is Debian Wheezy. My properly cooled and slightly overclocked FX 8320E does 650 hashes per second btw.

Had to configure with --ignore-incompatible-bdb and remove a "-msse41" from yescrypt.h in src/hash/yescrypt. More could be possible with some ARM optimization and compile option tuning, my only CXXFLAG was O3.

Too bad the hashrate almost doubled today.  

Wow nice, I tried to get it working on a pine64 which didn't work and it seemed to be missing x86 type operations so I assumed that yenten required x86 processors.  But that is interesting that you got it to work on ARM and not only that but on a non-ubuntu distro.  Would you mind writing up a little procedure on how to do it for a linux noob?  If this works on ARM it changes everything...

Also add up each core's hash/sec to get your total.

i’m still solo mining. anyone else?
