多谢提醒
我重新安装一遍，出现了类似错误，我简单搜索了一下好像是内存不足 ，安装具体信息如下：
/so ...

如果内存够大，swapoff -a，关闭交换分区，否则，扩大交换分区。

直接 lscpu就好了

谢谢！当时没仔细查过这类命令，不太熟悉~

你这个还好,我遇到了gcc版本过高导致无法编译，也是卸载了原来的gcc重新编译了对应的版本。

显示了哪个，就说明支持哪个指令集~

可以测试下AVX2_256与AVX512的速度差别。
因为我机子上测试发现在GPU加速时候，AVX512要略慢于AVX2_256
...

the tests are very important. Thanks.

非常感谢！

您知道怎样看自己的cpu适不适合AVX512吗？

1. for i in avx512 avx2 "avx[^2]" sse4_2; do grep -o -e $i /proc/cpuinfo; done
