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

[Dead Things]

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.

Yes - sorry, I should have mentioned that I tried build.sh first and it results in the same error, hence the attempt to take it step by step. I might try giving the drive another clean wipe and fresh install and try again then. Thanks for your reply!

Hi, I use cpuminer-opt-3.8.3.3-windows with cpu e5 2680(win server 2k12 R2) for yescryptr16 . But speed is slower when set -t is higher. for example -t 1 (144h / core), -t 4 (84h / core) -t 10(36h / core), who can help me ?
With -t 4

Attention users of Debian 8 Jessie.

Two users have reported that cpuminer-opt no longer compiles under Debian 8 as of v3.8.1. A code change
in that version introduced a SIMD instrinsic function that is not recognized by the Debain 8 compiler although
it is valid for the CPU architecture. It compiles successfully in Debian 9.

Debian 8 users are encouraged to upgrade to Debian 9 to take advantage of new optimizations avaiable in
the latest release of cpuminer-opt.

Hi.

Got the same problem as "Dead Things", but on an 2x Intel Xeon E5645 using Ubuntu 16.04 LTS
On systems with AVX I am using the precompiled linux version, but it is not possible to use this one on systems without AVX.

Tried to compile, and ran into the same problems.

I read the last posts in this thread to find help, but found "Dead Things" who has the same issue :=)

[joblo]

Hi.

Got the same problem as "Dead Things", but on an 2x Intel Xeon E5645 using Ubuntu 16.04 LTS
On systems with AVX I am using the precompiled linux version, but it is not possible to use this one on systems without AVX.

Tried to compile, and ran into the same problems.

/usr/bin/ld: cannot find -lpthreadGC2

What precompiled Linux version? It didn't come from me.

I built a Mint 17 (Ubuntu 16.04) system a week ago and have no problems compiling. I have no idea what's going wrong
for you and Dead Things. It should only try to link pthreadGC2 when compiling using mingw for Windows.
That's how I build the Windows binaries but when doing a normal build it links pthread as it should. The CPU shouldn't have
any effect on this, it's the build environment. Something is making it believe it's compiling for Windows.
Here is the code in configure.ac that controls it, it seems pretty clear:

Code:

if test "x$OS" = "xWindows_NT" ; then
   # MinGW
   AC_CHECK_LIB([pthread], [pthread_create], PTHREAD_LIBS="-lpthreadGC2",[])
else
   AC_CHECK_LIB([pthread], [pthread_create], PTHREAD_LIBS="-lpthread",[])
fi

I hope I'm not repeating, but I'm not sure which miner to run. My CPU supports these instruction sets:

MMX(+), SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, SSE4A, x86-64, AMD-V, AES, AVX, AVX2, FMA3, SHA

Running on a Threadripper 1900X

THAT IS A GOOD QUESTION--

After several pages of interesting bug catches, update notes, code reports, and technical data, I have lost track.  Most of my CPUs are slightly dated, and are still running v3.7.2.  Perhaps I should update and re-standardize on a newer version.       --scryptr

Try them and see? Anything unsopported won't run and you could do a quick benchmark on the the rest.

That's always a good fallback if you're completely lost. If README.txt isn't clear enough let me know.

[Cebula]

Try them and see? Anything unsupported won't run and you could do a quick benchmark on the rest.

I tried each of the programs and none crashed - which is good. Next question is how to do a benchmark.

does this support the primcoin/datacoin algo?

I cant seem to find it.

Hi joblo,
thx for this. It seems there is a bug in the Code

Freshly downloaded the sources on another machine and gone through configure.ac
My version shows as follows, which explains the problem we got. (I manually edited and corrected it, and it works fine now)
Another thing is that I have to install libgmpv4-dev to meet another requirement, but after that cpuminer binary got compiled fine

I belive it's calling TurboBoost... Maybe the YescryptR16 algo it's very sensitive to the cpu clock frequency and when only one core worked TurboBoost run this core on maximum clock frequency and slow down clock frequency when more core utilized.

Please don't speculate. YescryptR16 is less sensitve to CPU clock because it's memory hard. Adding more
CPU threads when memory bandwidth is saturated just causes CPU stalls. You also don't seem to
understand turboboost either. Turboboost only varies the CPU clock by about 15% and all cores run at the
same freq. Neither is the case with the data provided.

This processor is 2.7 GHz base with 3.4 boost
I understand that when using 1 core it is working at 3.4 & when using 2 i at 2.7

What I don't understand is why when using 3 cores the 3st is giving much more hash rate than the others.
I think I must learn more about HT

Thank you for your answers.
