Hello!! Good work! Will the support continue? When using Intel Xeon processors, do you need special software?

I have a 64 bit system!
I ask how to install? what libraries you need to download! You can set an example for CentOS7?Which file to edit and run?

good the explanations of your way to compile cpuminer through source 
by the way, can I compile your source into 32 bit processor system compatibility of windows ? I didn't found the instruction in https://github.com/JayDDee/cpuminer-opt/blob/master/README.txt and https://github.com/JayDDee/cpuminer-opt/blob/master/RELEASE_NOTES
and also into 32bit of linux if allowed
when I compile it into my 32 bit computer, appears the message below
please give me a clue. thanks

read first page. 32 bit is not supported

Requirements:
1. A x86_64 architecture CPU with a minimum of SSE2 support. This includes Intel
Core2 and newer and AMD equivalents. In order to take advantage of AES_NI
optimizations a CPU with AES_NI is required. This includes Intel Westbridge
and newer and AMD equivalents. Further optimizations are available on some algos
for CPUs with AVX and AVX2, Sandybridge and Haswell respectively.
Older CPUs are supported by cpuminer-multi by TPruvot but at reduced performance.
2. 64 bit Linux OS. Ubuntu and Fedora based distributions, including Mint and Centos are known
to work and have all dependencies in their repositories. Others may work but may require
more effort.
64 bit Windows OS is supported using the pre-compiled binaries package or may be compiled
with mingw_w64 and msys.
Legacy version 3.5.9.1 May provide better performance on some algos with
older CPUs that don't have AES NI. The legacy version is required to mine hodl
with a non-AES CPU. Most users should use the master version.

Hello!
Please help the girl!
How to install the miner and run on the server under CentOS7?
Three days of fighting I can not do anything!
Who can write stages and teams in order?

Please compile https://github.com/bubasik/cpuminer-opt-yespower for windows x64 with latest version openSSL
I get it only from libssl-1.0.0.dll, and it's slower.
In linux works faster than in windows.
in linux - 407 h/s
in windows 7 x64 - 350 h/s
Thank you.

how to use only 1 core or not full number of cores
Use -t option for the number of threads you want. For example -t 4
Another option to leave the miner use all cores and still let you use the computer is to start with lower prio. In windows it's start /low cpuminer....

Hi sir joblo ! Could you add support for CN-Fast please ?
You can look at https://medium.com/@officialmasari/cn-fast-miner-packages-4dd7b601abb1 for CN-Fast Miner Packages.
Thanks

There's so little information out there on the KNL Phis that I'm having trouble figuring out how to compile it on the phi. I've compiled it on the host multiple times no issue, along with other miners but I'm kinda stumped trying to get it to run on the Phi itself. There's so much info on the KNC but nothing on the KNL. Most of the commands on the KNCs are not compatible with the KNL series :/
I can't help with the Phi issues. Once they are sorted out I can look at any cpuminer issues.

Should be in the next release.

What about the PHI2? New luxcoin algo.

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.

-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.
