I'm very surprised that a man like Joblo has only 2 personns who gave him merit !!!

I am the third : +5 merit for you Joblo and I think it is not so much for all you kindly job.
I invite each person who use your CPUMiner-opt to give you some merit : it is a minimum.
Thank you Joblo/JayDDee for your job ;-).

You're right, the problem is for me Merit System is crap so I tend to not support or use it because it basically froze my rank, so I'm holding a bit - to use an euphemenism - of a grudge against it.

Also he's already Legendary so I don't think he needs more merits anyway.

By the way I gave him one Cheesy

its sad to see avx support is dropped .. looks like its hard to maintain them all together .. . time to upgrade cpu !! Smiley
and you making great job there joblo, keep it upp !!

Please explain. There should be no difference using the AES-SSE42 build on an AVX CPU.

Invalid shares on both Win10 Pro & Ubuntu-17.10.1-server-amd64  with new version, but with previous v3.8.7 it's all good. Config the same in all cases

Is it possible to run cpuminer in background? I think that every time I close my SSH-window, mining stops. I'm using UbuntuVM.

-B

Ok, where should I put '-B'? At the end of the command?

I'm trying to run command: ./cpuminer -a yescrypt -o stratum+tcp://[POOLADDRESS:PORT] -u [WALLETADDRESS]

Can somebody confirm which is the correct way to run this miner background on UbuntuVM?

I need to know where to put that -B in my command. Thanks in advance.

Anybody? I want to know how to run miner in background.

Good afternoon.
Dear Joblo, I really appreciate your work and ask you to look at cpu affinity.
The developer xmrig had a problem and he decided it.
It seems that some variable can not be more than 32 bits
I've tested everything on xenon e5 2680x2, and the same problem.

Thank you

andnet
I do not extract argon, I work with yescryptr32
According to your recommendations, he divides the speed of 600 h / s in half, but all the same I won it.
--cpu-affinity 0x55555555 and manually pointed to 16 physical cores and saw the desired 900 h / s. But not for long, the average speed is 750 h / s.
I just do not understand why they claim that I do not understand something when other developers had the same problems and they solved them.
Already brought the facts but ignored me.
Thank you

I have a processor
https://ark.intel.com/en/products/64583/Intel-Xeon-Processor-E5-2680-20M-Cache-2_70-GHz-8_00-GTs-Intel-KPI
Even when I put -t 8 --cpu-affinity 0xaaaa (0x5555) - 480 h / s
As soon as I start the second miner -t 8 --cpu-affinity 0xaaaa (0x5555), the speed is immediately divided into 300 h / s for each.
With the yescryptr16 algorithm, there is no such problem!

It is necessary to look at

Yescryptr16 is different from yescryptr32, you can't compare them. There is no problem.

argon2d500 not work
argon2d250 - on cpu-opt with sse42  HR is 27.5  , beastpoolminer with avx -30 . Why Joblo???

Yes argon2d500 s broken in v3.8.7.1. I'm looking into it.

Please provide more info: CPU, OS, build, etc.

Cpu-opt 3.8.72

There is no AVX targetted code anywhere in cpuminer-opt so there must be some better compiler
generated optimizations possible on Sandybridge vs Westmere. Most HW improvements on Sandybridge
should be transparent to the SW.

The only thing I found was a new instruction encoding format in AVX. Some (many?) of the
legacy SSE instructions have new encoding for AVX and they are possibly faster on a Sandybridge
CPU than the legacy SSE encoding of the same instructions. The new encoding would only be used if compiling
for AVX which would result in different binaries between Westmere SSE4.2 and Sandybridge AVX.

This is somewhat speculative but I can't think of any other reason the AVX compiler switch makes all
the difference.

It looks like I can't kill off the AVX build after all. It will return in th enext release, however, there will still
be no reporting of AVX algo features. AVX may affect some algos or all algos or may affect different algos
differently. They are the ghost optimizations. They exist, their effects can be felt, but they can't be seen.
