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

[Sir William]

Any chance to get the equihash algorithm added?  I'm still using nheqminer for my cpu.

Completely different design, too much work to integrate for no benefit.

[Sir William]

Fair enough.  Thanks for the reply.

[nizzuu]

joblo, do you plan to add huge pages support in the nearest future?

What best instruction for i7 7700k?

Im mining zoin using vps for tested

Hi,
is this cpuminer included as part of sniffdogminer package locayed here:
https://github.com/ahashpool/Sniffdogminer/releases

If not, can I run this cpuminer alongside sniffdog?

all flavors crash mining neoscrypt on windows 10 using intel avx2 capable cpu (i7 gen 8 ) : cpuminer-opt v3.8.3.3

Errata:

Neoscrypt crashes on Windows, use legacy version.

But the bottom line, hashrate is a function of how many hashes can a processor calculate

Agree with your comments about pool stats, that is what I am aiming to replicate because
it represents actual earnings.

But CPU performance is static, once it's benchmarked why would you need/want continuous
monitoring?

I'm using an automated script (personal fork of Megaminer) for all benchmarking and mining.
For benchmarking, I prefer to mine to a real pool, while also earning a little, without having to use "--benchmark"
For some algos, the time until initial share can be very high (as in minutes), which makes for unnecessary long benchmark
Sometimes the first share is submitted very fast (often happens for me with Lyra2z), and the reported rate, until the next share is submitted, is of 1 or 2 threads, which is very low and thus skews the benchmark
It is also used in a watchdog to see that the miner really works as it should

I'll consider that after I come up with a better way to report earnings. I'll have to figure out how pools convert a share
to a hashrate then do the same calculation locally if I have all the variables. That would be a new data term that would
probably be measured in hash rate and would be normalized based on share submission rate and share difficulty.
The existing HS or KHS could then be used as you request and represent CPU performance.

That would be "effective hashrate", its highly luck based, and not suitable for benchmarking.
Although it could be nice to have to see how is you luck

Precisely why I want real data when mining. Benchmarking is done in a controlled environment
free of extraneous variables like network latency, It's a theoretical value, essentialy a specification,
like a car's fuel consumtion rating. I don't need the fuel consumtion rating displayed on my dashboard
when I'm driving. I want real data, like fuel remaining and kms driven so I know how well it's
performing vs the specification.

I still have no idea why you would want theoretical data when real data is available.

Theoretical data allows me to immediately detect if anything is affecting the hashrate while mining (by comparing to the benchmark)
Be it overlocking, background process, other miner (GPU) or whatever and adjust accordingly

End to end monitoring will identify those issues as well as networking and pool issues. If you are concerned specifically
about system performance, run a system monitor. Cpuminer is not a system monitor and should not be used as one.

Hi!
Hope you help me. I have a 1PC for run cpuminer-opt without root access. But can compile it on my home PC. Is any way to compile cpuminer-opt with all dependencies? Otherwise I get errors "can not find *******.so" on 1PC. thanks in advance

That is an issue between you and the owner of the PC. I won't help you.

[sblack]

No any criminal. This is prepaid deducted server in internet. Even with root access I can not compile due to old centos version

Any insights for how to resolve this compile error:

Code:

/usr/bin/ld: cannot find -lpthreadGC2

This is a 4P Opteron 6278 box running Ubuntu 16.04.

Did do:

Code:

sudo apt-get install build-essential libssl-dev libcurl4-openssl-dev libjansson-dev libgmp-dev automake
sudo ./autogen.sh
sudo CFLAGS="-O3 -march=native -Wall" CXXFLAGS="$CFLAGS -std=gnu++11" ./configure --with-curl
make

Even tried:

Code:

sudo apt-get install libevent-pthreads-2.0-5
sudo apt-get install libpthread-stubs0-dev

...to no avail. Any insight or assistance would be greatly appreciated! Cheers!

Have you tried using ./build.sh? It's always best to use the recommended procedure first,
at least before reporting problems.

Unless you're using the legacy version (and you shouldn't with that CPU) you don't need CXXFLAGS.

As for the errors, pthreadGC2 is linked for Windows cross compile, I don't know why it's trying to
link it here. No one else has reported that problem and a lot of people use Ubuntu 16.04.
It should be just pthread.

Edit: I should note I didn't have to install anything special on Mint 18 (Ubuntu 16.04) for pthread.

There should be instructions at the pool. Most versions of cpuminer use the same syntax, you can always
try --help.  You should also read README.txt to determine the best exe for your CPU.
