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.

I also had to symlink libcblas.so to libcblas.so.3. It seems that liblapack.so references libcblas.so.3 instead of libcblas.so, the relevant error message being: /usr/bin/ld: warning: libcblas.so.3, needed by /usr/lib/gcc/x86_64-pc-linux-gnu/7.2.0/../../../../lib/liblapack.so, not found

I have same issue as @EpsilonDelta

There seems to be an issue where numpy is looking for libcblas.so.3 but it cannot find it. numpy works after symlinking libcblas.so to libcblas.so.3 but i'm not sure if that's a real fix. Is this package supposed to com with libcblas.so.3? is libcblas.so.3 different than libcblas.so?

After disabling intel_pstate and setting performance, my `scaling_cur_freq` is still always smaller than `cpuinfo_max_freq` and configure failed at checking cpu throttle. Solution: `echo 1 > /sys/module/processor/parameters/ignore_ppc` Then set `/sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq` works for me. ref: http://blog.patshead.com/2013/04/my-bios-is-limiting-my-cpu-clock-speed.html. p.s. I think my broadwell cpu (with model 0x3D) should be checked as IntCorei3 in CONFIG/src/backend/archinfo_x86.c (At present it will be checked as MACHOther)

In case it helps anyone, to build this package I had to disable hyperthreading in BIOS to stop the "throttling error" and then set the cpu governor to performance (cpupower frequency-set -g governor).

I encountered the same compilation problem and could fix it by adding the patch from http://stackoverflow.com/a/17952642.

@mamstriz: atlas-lapack-base didn’t complain at all, because it wasn’t optimized for your specific setup. That’s said, I don’t know why it was removed from the repo, but you still have the option to install blas, cblas and/or lapack instead for python2-numpy and the likes. ;)

Ok, this seems to be the reason why I failed to compile it without intel-pstate. My CPU uses Intel Turbo Boost. Is it possible to install this without such tricks? Many common packages need this, e.g. python2-numpy, r. The old package atlas-lapack-base didn't complain at all.

today I give it another try, since I noticed about this bug (https://bugs.archlinux.org/task/50202) at this time, I was successful by booting with `intel-pstate=disable` kernel parameter AND, together with, disabling the SpeedStep intel feature from the bios of my laptop now, is there a way to check out the performance, in order to compare the performance increase of the compiled package versus the pre-compiled one? EDIT: I was successful (compilation starts) even with the combination of: disabling intel_pstate, disabling ppc through kernel parameters and forcing the performance governor using cpupower tool EDIT2: I added a little section in our archwiki (https://wiki.archlinux.org/index.php/CPU_frequency_scaling#atlas-lapack_compilation) in order to help fellows. This is a very preliminary draft version, so every edit is welcome EDIT3: how does the compilation should handle intel TurboBoost technology, since this is disabled when disabling pstate?
