mine yescrypt he is more lucrative than xmr

It depends on the algo. Scrypt doesn't use AES so probably not. Cryptonight does so use a miner
with support for AES_NI.

Work with cryptonight  cpuminer fine   . affinity 85 -t 4 ( but 300 H only...xmr stak - 380 H on my 2600K)
 With  this scrypt work only 2 threads, 3456 atc not work  Algo not optimiz.
Tnx

hello, I have an i5 2500S that should have AES-NI. does this mean your cpuminer-opt is better than the cpuminer-multi? I'm just looking for the best scrypt miner for this intel i5 2500S processor. I've gotten up to 200 h/s on xmr-stak but that is cryptonight. would appreciate for some input

not have time in few days to check... if you...  maybe useful?

cpu i3-4160, speed 200 kh/s with lyra2z algo

That exe should work with your CPU. Are you sure it's crashing or is the window just closing?
You won't see error messages unless there is a pause in your bat file. The most common problem
with verium is running out of memory. The error messages can confirm this. Add more RAM or
reduce the number of threads.

Don't set affinity, always use the deafult!

help me start cpuminer and write cpu-affinity

You need to understand the architecture of your CPU. With Intel CPUs I have never had
an opportunity when I needed to set a custom cpu affinity. If I select 4 threads on
a 4C/8T i7 it runs one thread on each physical core, just as it should.

There is a belief that AMD CPUs map threads to cores differently and the default affinity
does not evenly distribute the miner threads aming the CPU cores and have suggested
using an alternating pattern where threads are alocated to every second logical core.

I don't have an AMD CPU so I have no advice to give. Maybe someday someone will come
up with a definitive answer.

In the meantime the guidelines for CPU affinity:

1. Never use it unless you are mining with fewer threads than locical CPUs.

3. In most cases the default is best.

3. Know your CPU architecture before messing with affinity.

4. Know if there is a problem with the default before messing with custom affinity.
Monitor CPU usage and teperature so you can confirm there is a problem before
thinking about using a custom affinity. If you can't confirm the default is wrong,
don't mess with it.

Hi, Joblo,
I use your miner since a lot of time, thank you for it.
Did you think one day to implement EquiHash algo in CPUMiner-opt ?
It's will be very helpfull.
When ?

installing ubuntu in win10:
https://docs.microsoft.com/en-us/windows/wsl/install-win10

compilation script is a few pages back in this topic

Can you tell me how to?

Thanks, i'll give it a try in a VM.

You can actually download a copy of Windows 10 from microsoft for free.

https://www.microsoft.com/en-us/software-download/windows10

when installing, it will ask if you have an installation key or not.  if not, it will still allow you to install and run.

This is something I could add to the procedure. I don't have Win10 so I can't try it myself.

I actually use the cross compile procedure on Ubuntu shell in Windows 10.
But it still does require some basic linux knowledge

use "-t" param to use specific amount of cores (i.e. "-t 3" on 4 core cpu)

Hey friends , can we have a line to use a percent of cpu ?
like
cpu max alloc percent ? or something like that in batch file ?

That procedure results in use old version of GCC (I tried to update it with no luck, build not works). I need to compile march native for Kaveri architecture. In XMRig (for example) I have 10% boost on precompiled version and 20% boost compared to cpuminer-opt using cryptonight and cryptonight-lite algo.
