Hello folks,
I *just* merged svn1555 into Sage :)
I build and tested for regressions in Sage 3.2.3 on
* FC 9 x86
* FC 9, OpenSUSE 10.3 x86-64
* RHEL 5.2, SLES 10 Itanium
* Solaris 10 Sparc and x86
* OSX 10.4 ppc
* OSX 10.5 32 bit *and* 64 bit builds
And eMPIRe also works on
* YDL 6.1 PS3 (a G5 variant)
Sage doesn't build on the PS3 yet due to M4RI build problems, but we
will fix that next week :)
>From William's referee report:
I did some multiplication timings (by multiplying m, n as above and
bigger) and empire is always about 3-5% FASTER.
But there is a speed regression over the Nils Moeller patch:
BEFORE (with GMP+Moeller):
sage: n = ZZ.random_element(0,2^(2^20)); m = ZZ.random_element(0,2^
(2^20))
sage: time k = m.xgcd(n)
CPU times: user 0.73 s, sys: 0.00 s, total: 0.73 s
Wall time: 0.74 s
AFTER (with eMPIRe):
sage: n = ZZ.random_element(0,2^(2^20)); m = ZZ.random_element(0,2^
(2^20))
sage: time k = m.xgcd(n)
CPU times: user 2.39 s, sys: 0.00 s, total: 2.39 s
Wall time: 2.39 s
William is doing some more testing, so stay tuned for more feedback.
I guess we should open a ticket for the xgcd speed regression.
Cheers,
Michael
