Hey I just installed, and make these notes, that might be useful for somebody else: Good explanation in atlas site: http://math-atlas.sourceforge.net/atlas_install/node5.html Follow this, the governor set by cpupower knows shit about CPU without this: http://unix.stackexchange.com/questions/121410/setting-cpu-governor-to-on-demand-or-conservative Summary: http://vincent.jousse.org/tech/archlinux-compile-lapack-atlas-kaldi/ ===========Steps=========== Permanent disable intel_pstate: Edit: /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="intel_pstate=disable" and update grub: grub-mkconfig -o /boot/grub/grub.cfg And then enable acpi-cpufreq module: su root echo "acpi-cpufreq" > /etc/modules-load.d/acpi-cpufreq.conf restart. Now cpupower can set frequencies properly. To disable throtling sudo pacman -S cpupower sudo cpupower frequency-set -g performance It should apply to all cores, but if it only apply to the first one: copy files to the other (4 in laptop) sudo cp /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor To restore: sudo cpupower frequency-set -g ondemand If not all cores are set: sudo cp /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor This stuff is only required at build time.

cblas link was fixed.

Sure.

can you change "mkdir ATLAS/build" to "mkdir -p ATLAS/build" so the package doesn't throw an error if you try to build it with the directory already existing from a previous build?

I solved "undefined reference to 'main'" by adding unset LDFLAGS to build() in python-numpy's PKGBUILD.

Again, broken numpy with /usr/lib/libcblas.so.3 missing.

Recompiling numpy from source with "yaourt -Sb python-numpy" after installing ATLAS fails for me when compiling python_xerbla.c with "undefined reference to `main'"

Is there any solution for this?

The best solution is to recompile numpy after replacing BLAS (no hacking required): yaourt -Sb python-numpy # be sure to add python-numpy to the IgnorePkg attribute of your /etc/pacman.conf to avoid breaking updates; you will need to compile it from source from here-on-out, which is easy to do

Since this package provides and conflicts with cblas, I think it should at least install all the shared objects that the cblas packages does. /usr/lib/libcblas.so.3 and /usr/lib/libcblas.so.3.8.0 are missing here.

Notably, the missing /usr/lib/libcblas.so.3 breaks python's numpy module!

Cant compile due to CPU throttling enabled. Followed instructions provided by @phcerdan on 2017-06-08 06:48 to disable it, and it worked. Could compile the package. Thanks @phcerdan
