I am trying to setup ATLAS, BLAS, LAPACK, and R on an OpenSuSE 12.2 server with an 8 core AMD athlon FX-8320. I have turned off the CPU frequency scaling using cpufreq and a script cfu from paste.opensuse.org/92162247 made by James McDaniel.

So following the instructions, here http://math-atlas.sourceforge.net/atlas_install/node45.html I didn't need to install gcc (that I know yet) I have gcc (SUSE Linux) 4.7.1 20120723 installed, g++, and gfortran the same version as gcc.

The instructions are to make a bogus configuration of ATLAS to determine the compiler flags to use. ATLAS is configured in the instructions as '../configure -b 64 -D c -DPentiumCPS=2200 -Fa alg -fPIC'. I modify this to what I think will work for my setup ' ../configure -b 64 -t 8 -Fa alg -fpic -A x86_64 -D c -DpentiumCPS=3500 -Si latune 1 --prefix=/usr/local/lib64 --with-netlib-lapack-tarfile=/opt/maths/lapack-3.4.2.tgz' I get these errors.

OS configured as Linux (1)

Assembly configured as GAS_x8664 (2)

Vector ISA Extension configured as  AVXMAC (3,504)
ERROR: enum fam=6, chip=8, mach=0
make[3]: *** [atlas_run] Error 44

make[3]: *** [atlas_run] Error 139
make[2]: *** [IRunArchInfo_linux] Error 2

Architecture configured as  UNKNOWNx86 (35)
ERROR: enum fam=6, chip=8, mach=0
make[3]: *** [atlas_run] Error 44
make[2]: *** [IRunArchInfo_x86] Error 2

Parallel make command configured as '$(MAKE) -j 8'
ERROR: enum fam=6, chip=8, mach=0
make[3]: *** [atlas_run] Error 44
make[2]: *** [IRunArchInfo_x86] Error 2
Cannot detect CPU throttling.

Atlas makes a Make.inc and if I fgrep F77 and F77 flags I get 'gfortran-4.7' AND '-O -mavx -fpic -m64'. Maybe the -mavx flag handles the AVXMAC error? Do I need -mavx? I will proceed with my instructions...

（不是真正的答案，但很难作为评论阅读）：

关于 Dirk 建议使用 OpenBLAS 的更多注意事项。

我还使用 OpenBLAS（在 Ubuntu 和 CentOS 系统上）。

  • 在 8 核和 12 核机器上对我来说重要的一个考虑因素是 OpenBLAS 允许动态设置要使用的线程数，而ATLAS 不允许。为了从 R 中动态设置线程数，我使用Simon Fuller 的 OpenBLASThreads。

  • OpenBLAS 在这两个系统上构建起来非常简单。

  • 二进制 .deb 包可用，但上次我检查它们时，它们的最大可能线程数设置为 2。但是，这将改变。到目前为止，我还在具有> 2 个内核的 Ubuntu 机器上从源代码构建库。
