@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?

Have problems too, using TLP. Have the same lines in dmesg:

[ 0.033503] ENERGY_PERF_BIAS: Set to 'normal', was 'performance'
[ 0.033503] ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8)

A neat solution would be to add 'wait' function beside the prompt - and gave user a chance to change cpu-governor before starting the build procedure.

Similar solution can be found in Slic3r-git PKGBUILD which allow user to tune the branch before starting the build.

I've already tried it

PS: my CPU is an Intel Broadwell

EDIT: maybe related to these lines found with dmesg?
[ 0.027339] ENERGY_PERF_BIAS: Set to 'normal', was 'performance'
[ 0.027339] ENERGY_PERF_BIAS: View and update with x86_energy_perf_policy(8)

Try also hints from http://math-atlas.sourceforge.net/atlas_install/node5.html - might help. There are too many ways to set this to do automatically - and it might require root permissions for some - so it cannot be part of PKGBUILD unfortunately.

given that, it's the first time I'm trying to compile this package,
I'm not able to compile it!
It always gives me the "throttling error"

I've tried every kind of suggestion, stated below but with no luck...

PS: I'm on a laptop, with `tlp` installed

I've made some changes to this package. Please test if possible. It needs further refreshment, but I don't have time for it now. Patches/PKGBUILDs with updates are welcome, I can also pass this to someone with more time at hand.

@peder2tm, yep, failed at the same step for me. It is definitely a bug.
