Maybe I advanced a little in this problem. I found that your patch
ATLAS-3.8.1-ppc-g4-7447-detect-fix.patch is not applied in sage. After applying
this patch, it can detect architecture PPCG4. Here are the result with
atlas-3.8.1.p2 in 3.0.4.alpha1:
---------------------------------------
OS configured as Linux (1)
Assembly configured as GAS_PPC (4)
Bad VECFLAG value=0, ierr=0, ln2='VECFLAG=0
'
Vector ISA Extension configured as (0,0)
Architecture configured as PPCG4 (4)
Bad CPU MHZ value=0, ierr=0, ln2='CPU MHZ=0
'
Clock rate configured as 0Mhz
-----------------------------------
and
-----------------------------
real 62m10.407s
user 47m47.740s
sys 4m38.025s
Successfully installed atlas-3.8.1.p2
-------------------------------
For comparison (atlas-3.8.1p1 in sage-3.0.3) I need long time:
-------------------------
real 450m35.791s
user 371m58.504s
sys 16m33.417s
Successfully installed atlas-3.8.1.p1
-----------------------------------------
