Hello folks,
as expected changes over 3.4.1.rc4 are minimal:
Merged in Sage 3.4.1.final:
#5284: Michael Abshoff: Set sage-flags.txt up to SSE2 only when
building Sage in SSE2 only mode/remove SSSE3 and SSE4 flags (followup
to #5219) [Reviewed by Gonzalo Tornaria]
#5829: Minh Van Nguyen: copyright on standard documentation [Reviewed
by Dan Drake]
To build an SSE2 only binary do the following:
SAGE_SIMD_MODE=SSE2; export SAGE_SIMD_MODE
make
This will obviously have an impact on performance and I am afraid it
could be significant for certain problems. If anyone bothers to do two
builds please let us know. Good candidates for performance regressions
would be linear algebra, i.e. anything that involves ATLAS.
All the bits are as usual in
sage.math.washington.edu/home/mabshoff/release-cycles-3.4.1/
I am building my 3.4.2.alpha0 merge tree and should merge in a couple
hours. Hopefully 3.4.2.alpha0 will drop tomorrow.
Cheers,
Michael
