I'm on SUSE Linux Enterprise 10/11 machines. I launch my regressions to a farm of machines running Intel processors. Some of my tests fail because my tools are built using a library which requires AVX/AVX2 instruction support. I get an Illegal exception
error.
我在使用SUSE Linux Enterprise 10/11计算机。我将回归发送到运行英特尔处理器的计算机的农场。我的一些测试失败是因为我的工具是使用需要AVX / AVX2指令支持的库构建的。我收到了非法异常错误。
In Linux, is there any commands I can use to determine what is the CPU code/family name?
在Linux中,是否有任何命令可用于确定什么是CPU代码/系列名称?
I believe AVX and AVX2 are available onward from Intel SandyBridge and Haswell family, respectively.
我相信AVX和AVX2分别可以从Intel SandyBridge和Haswell系列开始。

On linux (or unix machines) the information about your cpu is in /proc/cpuinfo
. You can extract information from there by hand, or with a grep command (grep flags /proc/cpuinfo
).
在linux(或unix机器)上,有关你的cpu的信息在/ proc / cpuinfo中。您可以手动或使用grep命令(grep flags / proc / cpuinfo)从那里提取信息。
Also most compilers will automatically define __AVX2__
so you can check for that too.
大多数编译器也会自动定义__AVX2__,因此您也可以检查它。

Run this command:
运行此命令:
grep avx /proc/cpuinfo
Or
要么
grep avx2 /proc/cpuinfo
This will give you:

You can test for availability of SIMD instruction sets and other CPU features by examining /proc/cpuinfo
, e.g.
您可以通过检查/ proc / cpuinfo来测试SIMD指令集和其他CPU功能的可用性,例如:
$ grep avx2 /proc/cpuinfo
flags : fpu vme ... sse4_1 sse4_2 ... bmi1 avx2 ... bmi2 ...

You can also run lscpu
and check the list of instructions at the end.
您还可以运行lscpu并在最后检查指令列表。
