centos6.7安装openblas错误
centos系统:CentOS release 6.7 (Final)
安装OpenBLAS
# Install OpenBLAS at /usr/local/openblas
git clone https://github.com/xianyi/OpenBLAS
cd OpenBLAS
make -j $(($(nproc) + 1))
sudo make PREFIX=/usr/local install
cd ..
执行命令:make -j $(($(nproc) + 1))
出现下面类似错误:
../kernel/x86_64/dgemm_kernel_4x8_haswell.S:1759: Error: no such instruction: `vpermpd $ 0xb1,%ymm0,%ymm0'
https://github.com/JuliaLang/julia/issues/7653#event-143521038
解决方法:
Add "#define NO_AVX2 1024" to the file cpuid.h as the last second line. Good day!
