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.

Atlas compiles with GCC 4.7 if I configure it with -D c -DWALL in addition to other settings in PKGBUILD. This uses wall timer for timing meaning that computer mustn't be busy. I also booted with intel_pstate=disable because processor frequency didn't stay at 3.4 Ghz on performance governor if intel_pstate was configuring frequency.

@MarBur that's one great bug report. Let's see how upstream responds.

giniu commented on 2013-09-17 17:11 (UTC)

I don't think this is related to package itself, I will monitor this issue upstream. Thanks for reporting.

MarBur commented on 2013-09-17 13:48 (UTC)

I have the same error: https://dl.dropboxusercontent.com/u/25828692/full_log.log But I think the real error is higher up: make[5]: *** [RunMADef] Aborted (core dumped) make[5]: Leaving directory `/tmp1/yaourt-tmp-mabu/aur-atlas-lapack/src/ATLAS/build/tune/sysinfo' xsyssum: /tmp1/yaourt-tmp-mabu/aur-atlas-lapack/src/ATLAS/build/..//tune/sysinfo/GetSysSum.c:92: getfpinfo: Assertion `system(ln) == 0' failed.

I adopted this package. For now I just updated it and walked around archive bug. I will clean it up during following updates.

gborzi commented on 2013-01-28 15:10 (UTC)

I'm going to orphan this package. I'm using openblas now, and this package is a pain to maintain.

giniu commented on 2013-01-27 11:43 (UTC)

When you update ATLAS to new release (atlas 3.10.1) look out for bsdtar issue: http://code.google.com/p/libarchive/issues/detail?id=299 for some reason it fails to extract the archive, you can walk around this, add sources to noextract and extract them by hand using "tar"

PedsXing commented on 2013-01-27 09:53 (UTC)

Running ATLAS' performance check with make time I seem to get a rather bad performance compared to the reference performance obtained by the ATLAS authors. http://pastebin.com/7DwbtJwX Is there any explanation for that? Does anyone get better results?

giniu commented on 2012-11-29 21:21 (UTC)

Are you sure you don't want to bump it? The package without this space is somewhat 11mb smaller if I remember correctly results I got.
