Comment (by SimonKing):
First of all: make ptestlong works with the two new spkgs (even though I
have a few other patches applied...).
Here is a small timing.
Vanilla Sage-5.0.rc0:
{{{
sage: K = GF(2)
sage: %time A = random_matrix(K,20000,20000)
CPU times: user 0.29 s, sys: 0.02 s, total: 0.31 s
Wall time: 0.31 s
sage: %time B = random_matrix(K,20000,20000)
CPU times: user 0.23 s, sys: 0.03 s, total: 0.26 s
Wall time: 0.27 s
sage: %time (A*B).rank()
CPU times: user 11.70 s, sys: 0.05 s, total: 11.75 s
Wall time: 11.81 s
19937
}}}
Sage-5.0.beta13 with the new spkgs (and some other patches that shouldn't
affect the timing for matrix multiplication):
{{{
sage: K = GF(2)
sage: %time A = random_matrix(K,20000,20000)
CPU times: user 0.30 s, sys: 0.03 s, total: 0.33 s
Wall time: 0.33 s
sage: %time B = random_matrix(K,20000,20000)
CPU times: user 0.32 s, sys: 0.01 s, total: 0.33 s
Wall time: 0.33 s
sage: %time (A*B).rank()
CPU times: user 11.70 s, sys: 0.10 s, total: 11.80 s
Wall time: 11.83 s
19937
}}}
Well, at least there is no slow-down...
Do you claim that the new version of M4RI is faster? You do claim a speed-
up for M4RIE, on #12841.
