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 was finally able to get this working. The reason that the build was failing was that the maximum CPU frequency was being limited by the BIOS. I had to tuhrn off the max CPU freq limit set by the BIOS and ensured that the maximum frequency was that allowed by cpupower, namely 2.401GHZ. See: https://wiki.archlinux.org/index.php/CPU_frequency_scaling#BIOS_frequency_limitation

Right, I tried to make it clear from my initial post that I've already done what was instructed on that page and the linked SE answer. I am still getting the "CPU Throttling is enabled!" error. Some output: $ cat /sys/devices/systemt/cpu/cpu*/cpufreq/scaling_governor performance performance performance performance $ cpupower frequency-info analyzing CPU 0: driver: acpi-cpufreq CPUs which run at the same hardware frequency: 0 CPUs which need to have their frequency coordinated by software: 0 maximum transition latency: 10.0 us hardware limits: 400 MHz - 2.40 GHz available frequency steps: 2.40 GHz, 2.40 GHz, 2.30 GHz, 2.10 GHz, 2.00 GHz, 1.80 GHz, 1.70 GHz, 1.50 GHz, 1.40 GHz, 1.30 GHz, 1.10 GHz, 1000 MHz, 800 MHz, 700 MHz, 500 MHz, 400 MHz available cpufreq governors: ondemand performance current policy: frequency should be within 400 MHz and 2.10 GHz.

see http://vincent.jousse.org/tech/archlinux-compile-lapack-atlas-kaldi for disabling CPU Throttling.

bartbkr commented on 2016-04-09 14:49 (UTC)

I have Intel Core i5 processor. I've confirmed that now using the acpi_cpufreq driver and intel_pstate=disable on boot. scaling_governor for all four cores is set to performance. I am still getting the "CPU Throttling is enabled!" error and cannot build. Any suggestions?

greyltc commented on 2016-02-27 12:07 (UTC)

My cpu scaling driver is intel_pstate. By default I'm using the performance governor. Can anyone give me a tip on how to compile this package *without* having to reboot?

giniu commented on 2016-02-25 14:36 (UTC)

@arojas - yes, but provides+conflicts is good anyway in this case I think.

arojas commented on 2016-02-25 12:00 (UTC)

No package should depend on atlas-lapack-base. If some do, it's a bug and should be fixed. Packages should depend on atlas-lapack, atlas-lapack-base is provided as a generic implementation in the repos so that official packages (such as sagemath) can depend on atlas-lapack, but it should be clear that atlas-lapack is the 'right' package to use.

Hi - I will deal with providing atlas-lapack-base together with next upstream release (when this package was built, there was no atlas-lapack-base yet). It will come soon.

budgerigar commented on 2016-02-20 23:31 (UTC)

Maybe there should be a provide for atlas-lapack-base because some packages depend on it which is a official package, and atlas-lapack can replace it.

See http://vincent.jousse.org/tech/archlinux-compile-lapack-atlas-kaldi/ for how to turn off cpu throttling if you are using intel_pstate. (TL;DR: boot with intel_pstate=disable, then modprobe acpi-cpufreq, then cpupower frequency-set -g performance). I did this, and it's no longer aborting due to cpu throttling, but now I'm having a strange problem (64 bit): cd bin/ ; ./xatlas_build -1 0 -a 1 -l 1 Can't recognize 'make IArchDef.grd ' as an internal or external command, or batch script. Is it using the wrong shell or something?
