Hi
I have compiled sage 8.9 on a KVM used as a master image for a computer lab.
The CPU is presented as model name : Intel Xeon E3-12xx v2 (Ivy Bridge)
Imaging is using systemimager based on rsync.
On the newer lab machines with Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz
the sage copied to the lab machines works fine.
On the older lab machines with Intel(R) Core(TM)2 Duo CPU E8400 @
3.00GHz
there is a crash as attached.
Is there a flag I can set at compile time to compile for the older CPUs by
disabling use of some instruction not available on the older CPUs, which is
what I suspect is happening?
Regards,
Jan
