Bug 375193 – [bicatali-overlay] sci-libs/atlas-3.9.41: ebuild shouldn't die when "performance" is not set for CPU

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Juergen Rose 2011-07-14 17:31:45 UTC]

On two of three systems with atlas-3.9.41 'emerge -uveDN system' fails with:
...
>>> Emerging (592 of 712) sci-libs/atlas-3.9.41 from bicatali
 * atlas3.9.41.tar.bz2 RMD160 SHA1 SHA256 size ;-) ...                  [ ok ]
 * lapack-3.3.1.tgz RMD160 SHA1 SHA256 size ;-) ...                     [ ok ]
 * CPU 0 is not set to performance
 * Run cpufreq-set -r -g performance as root
 * ERROR: sci-libs/atlas-3.9.41 failed (setup phase):
 *   atlas needs all cpu set to performance

I could set performance mode before starting 'emerge -uveDN system', but I would prefer if the atlas-3.9.41.ebuild would set the performance mode reset it after finishing. Is there any way?

Reproducible: Always

From what overlay are you getting this package?

It is from the bicatali overlay. And besides other improvement it fixes problems with the segfaulting eigen function in R (compare Bug 370447).

Next time please indicate overlay in summary, thanks

I removed the die, but will not set the cpu frequency within an ebuild. Now it's at your own risk to get a non-performing atlas.
