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

[joblo]

Thanks for fix, you still have old link though so we cant actually download this fixed miner

Links have been updated. Pleas delete the bad links from your post.

yescryptR16 algorithm support is not perfect

That is a pool issue, likely overload as discussed in the yenten thread.

Can I use cpuminer-opt for LAN mining?
How should it be configured
thank you for your help!

I don't understand the question. If you mean solo mining connecting to the wallet instead of a pool,
then yes it should work. But be sure to include htttp:// in the URL because it will default to stratum otherwise.

Good to read you got it working. You should check that the compiled SW features match your CPU architecture for best
performance.

It should already, because it was compiled in the real machine, or it should not?

edit: in you opening post there are some minor typos here? (CLAGS is CFLAGS? obvious for an advanced user but deadly for a novice if it's the case, I'm the second type)

Users with openssl 1.0.1 (Ubuntu 14.04) may get better perforance by adding "-DUSE_SPH_SHA" to CLAGS.

Thanks for pointing out the typo, fixed. I don't expect too many newbies to be using old distros. You could consider the
error a competency test, if you can't find the error you shouldn't be trying to customize the compile.  You passed.

The Virtualbox emulated CPU may not have the same architecture as the host and may be missing some newer features,
particularly with older versions of Virtualbox. On the other hand the old CPUs are not likely to have them either.
It's just something else to watch for.

One thing I have found is that neoscrypt fails to initialize in the version i have compiled (both avx2 and sha)

Benchmark is broken for neoscrypt but pool mining works. Benchmark is broken for a few algos and I don't really
care to try to fix them.

all the algos in the table i posted benchmark fine with your version, but in this case, it actually breaks completely, even with real pools


p.s.
can you enable the api to report the hashrate before the 1st accepted share?

I can't do much if it's only your cross compile that's failing.

The hash rate is only meaningful when a share is submitted. Reporting the per-thread hash rate on every scan
would increase the traffic.

tell me on which of the files will be mining above the algorithm m7m on the processor i7-3770

already try v3.7.2 but there is 2 red line inside my bat file
"stratum_recv_line failed"
"stratum connection interrupted"

Should I be worried that my CPU, software, algo all supports AVX but it's not being used? Or does using AVX2 mean that AVX doesn't matter?

Code:

CPU: Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz
CPU features: SSE2 AES AVX AVX2
SW built on Nov  2 2017 with GCC 5.4.0
SW features: SSE2 AES AVX AVX2
Algo features: SSE2 AES AVX AVX2
Start mining with SSE2 AES AVX2

it uses the best available implementation, so yes, AVX doesn't matter when you have AVX2

Thanks for confirming.

you are missing gmp library
i would guess that its gmp-devel that you need to install

[runningwithbeer]

I had the wrong package for CentOS. Thanks for the push in the right direction.

[Bluecheese]

Has anyone made a build for a Mac or can point me in the right direction for compiling?
