[LOCKED] cpuminer-opt v3.12.3, open source optimized multi-algo CPU miner

Could you update Windows compilation instructions?

A better way was found but it is compiled on Linux for Windows. This isn't practical for Windows users
as they would need Linux as well.

Unfortunately there is no good solution at this time for Windows users to compile from source..

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

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

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.

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

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 ?

How can I choose cpu-affinity for 32 cores correctly?
And why CPU # 30: 512 H, 349.15 H / s other CPUs # 17: 301 H, 321.58 H / s?
Was it CPU # 30 more successful?)
Thank you

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.

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!

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

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.

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

mine yescrypt he is more lucrative than xmr

hi,
possible to use in solo mining for ZOI?
if yes any documentation?
many thanks,

Unless someone reading here has actually tried it you're probably better off asking in the ZOI thread.
If ZOI supports getwork protocol then you should be able to solo mine with cpuminer-opt. You'll need
the specific instructions for ZOI.

Caveat: Not all algos in cpuminer have been tested with getwork. If you're double sure you're  doing
everythig right, come back and report your results and I'll look into it.   

[felixbrucker]

i tried once and iirc it was not throwing any error but i also could not verify it was working. However solo mining hexx was possible (it uses the same algo). Hope this helps

After I posted my reply I read a PM from Hexxodev and it appears a wallet upgrade has
dropped getwork for GBT. GBT in cpuminer-opt likely doesn't work.

Getwork is known to work with most algos (after a couple of fixes)  as they all use the same protocol.
Cryptonight is the only algo known not to work (different protocol).

GBT, on the other hand is completely unknown.

Edit: it looks like ccminer is having a similar issue with coins switching to GBT.
