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 could not build it today. Here are the last few messages from makepkg -s. (...) cp /home/nlw/aursrc/atlas-lapack/src/ATLAS/build/lib/libf77blas.a /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/. chmod 0644 /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/libf77blas.a cp /home/nlw/aursrc/atlas-lapack/src/ATLAS/build/lib/libptcblas.a /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/. cp /home/nlw/aursrc/atlas-lapack/src/ATLAS/build/lib/libptf77blas.a /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/. chmod 0644 /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/libptcblas.a /home/nlw/aursrc/atlas-lapack/pkg/usr/lib/libptf77blas.a make[1]: Leaving directory `/home/nlw/aursrc/atlas-lapack/src/ATLAS/build' ==> Tidying install... -> Purging unwanted files... -> Compressing man and info pages... -> Stripping unneeded symbols from binaries and libraries... ==> WARNING: Package contains reference to $srcdir ==> Creating package... /usr/bin/makepkg: line 1129: /usr/bin/du: No such file or directory /usr/bin/makepkg: line 1130: * 1024 : syntax error: operand expected (error token is "* 1024 ") ==> Finished making: atlas-lapack 3.8.4-3 (Thu Jun 14 14:37:52 BRT 2012) ==> Finished making: atlas-lapack 3.8.4-3 (Thu Jun 14 14:37:53 BRT 2012) nlw@pathfinder:~/aursrc/atlas-lapack$

Why has this package been flagged out of date? The stable atlas release is still at 3.8.4, cpupower is still in community, while cpufrequtils is in extra. In case it doesn't compile please post the error message.

cpufreq-* has been replaced/deprecated by cpupower utility

@oscarvarto I've just uploaded a new PKGBUILD that fix the problem with a line that unsets MAKE before building atlas. I've not changed the pkgver, recompiling this package is a pain.

makepkg fails with the following message: make[2]: Leaving directory `/home/oscar/atlas-lapack/src/ATLAS/build/bin' ERROR 437 DURING CACHESIZE SEARCH!!. CHECK INSTALL_LOG/Stage1.log FOR DETAILS. $echo $MAKE make -j6 When I changed to $ export MAKE=make compilation was successful.

Sorry for forgetting the patch. The package has been updated again.

gdiscry commented on 2011-12-10 14:15 (UTC)

And finally, you should use "egrep '^processor' /cpu/cpuinfo" when detecting the number of CPU, I have an old Pentium M and the model name contains the string "processor" too, so the PKGBUILD thinks I have 2 processors.

gborzi commented on 2011-12-10 14:13 (UTC)

@Murmex I did the requested changes. The problem with the lapack md5 is due to the fact that at netlib they keep changing the tarball without changing the version number. It is already the second time that it happens.
