Re: [ANN] cpuminer-opt v3.12.6.1, open source optimized multi-algo CPU miner

We wrote an article on how to install AOCC (AMD Optimizing C / C ++ Compiler) and tested CPUminer it on a ryzen 2600 CPU.

Install depends

Code:

sudo apt-get install -y git
sudo apt-get install -y automake autoconf pkg-config libcurl4-openssl-dev libjansson-dev libssl-dev libgmp-dev make g++
sudo apt-get install -y lib32z1-dev

download aocc-compiler-2.1.0_1_amd64.deb from https://developer.amd.com/amd-aocc/

install AOCC in Ubuntu

Code:

sudo dpkg -i aocc-compiler-2.1.0_1_amd64.deb
source /opt/AMD/aocc-compiler-2.1.0/setenv_AOCC.sh

check the installed AOCC compiler

Code:

clang -v

Tested cpuminer-opt on yespower algos.
you need to remove all algorithms from the miner, except yespower

Code:

git clone your cpuminer-opt

if error in coinfigure - use olds version cpuminer-opt

Code:

chmod +x autogen.sh
./autogen.sh || echo done

configure with AOCC

Code:

./configure --with-curl CC=clang CFLAGS="-O3 -march=native -funroll-loops -fomit-frame-pointer"

Code:

make

benchmark

Code:

./cpuminer --benchmark -a yespower -t 1

You can check this compiler on your favorite algorithm.
