Hey I just installed, and make these notes, that might be useful for somebody else: Good explanation in atlas site: Follow this, the governor set by cpupower knows shit about CPU without this: Summary: ===========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.

How to disable frequency scaling on AMD CPUs? I tried echo performance | tee /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor but that doesn't seem to be enough for this package.

@bazza, the option --cripple-atlas-performance leads to unoptimized binaries, it's better to disable CPU throttling while building ATLAS.

   ./configure --prefix=/usr \
                --shared \
                --with-netlib-lapack-tarfile="$srcdir/lapack-$_lapackver.tar.gz" \
                --cripple-atlas-performance # add this

I got an error message saying "gcc: error: unrecognized command-line option ‘-V’" when building from AUR.

@jbe456, yes, atlas-lapack is a replacement for blas, lapack, and cblas.

During install, it fails because of conflicting files:

error: failed to commit transaction (conflicting files)
atlas-lapack: /usr/include/cblas.h exists in filesystem (owned by cblas)
atlas-lapack: /usr/lib/ exists in filesystem (owned by blas)
atlas-lapack: /usr/lib/ exists in filesystem (owned by cblas)
atlas-lapack: /usr/lib/ exists in filesystem (owned by lapack)
atlas-lapack: /usr/lib/ exists in filesystem (owned by lapack)
atlas-lapack: /usr/lib/ exists in filesystem (owned by lapack)
Errors occurred, no packages were upgraded.

Should I uninstall blas, cblas and lapack before installing this lib? What is the recommended fix?

You might want to mention those conflicts in the package description in a similar way than is doing.

Fails had during make check.

Has something to do with newer gcc/gcc-libs/gcc-fortran. I downgraded to 8.3 for each and it installed no problem. Not sure how you would handle this in a PKGBUILD

@ajong, yes, it is. "Tests" are the auto-tuning procedures which the efficiency of the ATLAS package is based on.

The install is running tests for what seems to be like forever. It's run for three hours so far, is this normal? Is there a way to skip the tests?

ajong commented on 2020-04-08 00:05 (UTC)

Got compile error about CPU throttling, followed phcerdan's advice and it worked!
