Has anyone been able to run Xeon Phi coprocessors using this miner. In specific a Xeon Phi 7220A or other x200 PCI-E equivalent?
Have you tried? What problems do you encounter? I tried to compile it natively using icc but I am getting compile errors. I'll try it again sometime this week to see if I can get it to work. I believe "native" in ths context refers to how the application is run, not how it is compiled. A native compile is when compiling on the same device as the app will be run. Have you tried compiling on the phi using GCC? I don't know if it's supported but it would avoid any incompatibilities between cpuminer and ICC. |

When I try mining xmr I dont get anywhere the hashrate on fx-8350 that I get in xmr-stak or xmrig and would prefer to use cpuminer-opt because you support more coins I no its my settings so how do I use these settings in cpuminer-opt
"cpu_threads_conf" : [
{ "low_power_mode" : true, "no_prefetch" : false, "affine_to_cpu" : 1 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 3 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 5 },
{ "low_power_mode" : false, "no_prefetch" : false, "affine_to_cpu" : 7 },
{ "low_power_mode" : true, "no_prefetch" : false, "affine_to_cpu" : 0 },
],
Thanks for any help
-t 5 --cpu-affinity 0xab, but you should use 4 threads (8MB cache) and you might have to play with affinity to get them properly distributed. |

msys and mingw_w64 can anyone gives the exact urls?
i cant run build.sh in msys command line
im trying to change dir and nothink works
Compiling on Windows requires some unix skills, you may be better off using the pre-built binaries. If you want help compiling provide more info on what you did. |

hi
is possible add more alternative pools if first one crashes.
is somewhere instructions how to config?
That can be handled by external programs, there are several promoted in the mining forum. |

Thank you, got last question I promise  . Is there a option to run cpuminer v3.8.8.1 ussing sse4.2 on cpu(i3-380m) that does not support aes? When i try to run it on legacy version it says that cpu supports only sse2 but in v 3.8.8.1 it shows dat cpu supports sse4.2. There are no SSE4.2 targetted optimizations in cpuminer so any reporting of SSE4.2 capabilities is just FYI and doesn't really mean anything. You should use the SSE2 build if your CPU doesn't have AES. |

So if i have 2 cores 4 threads i should use -t 2 cpu-affinity 0x5?
It would help if you said what you're trying to accomplish. Unless you have a good reason, as a newbie I doubt you have one, you shouldn't be messing with this. If you only want to run 2 miner threads use -t 2. Ideally each thread will run on a different physical core, if not you can use --cpu-affinity to explicitly specify which logical cores should be used, but you need to understand the what and the why before the how. I want to use affinity because when i dont, miner uses 100% of cpu and thats my pc for work. Even more i noticed i get better h/s using affinity than otherwise. From my understanding affinity links thread to cpu thats why you can achieve better perfomance by using this option. So if i want to link threads to physical cores (which i got 2 in i5-5200u) i need to use 101 in binary(1 for every physical core), that converts to 5 in hex so it gives me 0x5 for cpuminer. But the thing i dont understand is when i only use affinity without -t it still uses all 4 threads, thats why i asked if i should use -t 2 option for my 2 core 4 threads cpu. I believe your questions have been answered. |

Thank you very much, but if i dont use -t option, all threads are still doing job. I got i5-5200u - 2 cores 4threads so i use affinity 0x5, same thing on another pc with i3-380m also 2 cores 4 threads and still all threads work anyway.  CPU affinity is only used with -t less than the number of CPU cores. |

I can not use this miner at all. I have windows 10 build 1803 (no choice hardware change + new install) and a Ryzen 5 2400G with 8GB DDR4 2400MHz.
Everytime I launch the miner, the window closes at once, even while running as admin or with compatibility mode activated.
How could I solve this issue ?
Thanks.
README.txt: cpuminer is a console program that is executed from a DOS command prompt.
There is no GUI and no mouse support.

Sure but replace the old PSUs instead of adding a second one.

Your CPU supports AVX, not AVX2. my cpo e5-2690 v4 its support AVX2 Windows or Linux? If Linux how did you compile? If Windows did you try the AVX2 build? |

Thanks, but neither is cpuminer compatible. Both are written in an OO language I'm not famliar with. I'd have to learn either PHP or Java before I could determine if I could convert it to cpuminer compatible C. hey maybe this one https://bitbucket.org/cryptogone/ariocppminer/srcArionum CPU miner implemented in C++ That helps but still a lot of uncertainty. Arionum is more complex than the other argon2 coins so a lot more work. I'm not ready to go there yet. |

Hello.
I tried to build with Ubuntu 18.04 LTS, but I could not.
/usr/bin/x86_64-linux-gnu-ld: cannot find -lz
...
What should I do?
sudo apt-get install zlib1g-dev |

It's a good effort but unfortunately the miner is written in GO. |

Anyone using cpuminer-opt to mine cryptonight may be seeing variant mismatch warnings. https://github.com/JayDDee/cpuminer-opt/issues/136I'm still investigating but I have seen it intermittantly at Nicehash. I don't know if it's Nicehash only or related to a specific coin. I suspect it happens at Nicehash when it switches orders, likely mining a different coin. The V7 spec states that byte zero of the data blob is the version byte. A version less than 7 is the old cryptonight and 7 is V7. However I've seen version 9 while mining V7 at Nicehash. In spite of the warning the shares were accepted. I inserted the warning based on the spec to help users make sure they are using the correct variant. However, it seems to have backfired. If anyone has any more info whether it happens at other pools using either the original or V7 and whether the shares are accepted it might help better understand the issue. Also, if anyone has any useful info about the other cryptonight variants, or any of the other requested algos (sigh) ... |

Could it be configured to run Argon2i + SHA512 (Arionum)?
The miner already has both argon2i code and sha512 code but there are some issues. First the Argon2i version is currently untested although I see no reason it shounldn't work. Second I need Aronium's Argon2i parameters. They can be obtained from a spec or sample code. Additionally there are differences in the implementations or Argon2 and Sha512 that need to be resolved. Argon2 uses linear vectors while sha512 uses parallel vectors. Without going into technical detail, this complicates the implementation of an algo that uses both. With all that it should be doable. |

It would be fair miners like us help you by funding buying a X299 platform...
I am using your miner since 1 year, half time (half mining aeon with xmr-stack) with a xeon 2696V4 and I have just switch to an i9 7960x.
I have just sent some mbtc.
Thank you very much for the donation, every little bit helps. |
