I didn't install the package with SAGE_CHECK=yes, but I guess I should...
Anyway, the Sage test suite (make ptestlong) works.
I tried to verify your claim that it became faster for exponents between 4
and 8. I tested 6. First, in vanilla sage-5.0.rc0:
{{{
sage: K.<z> = GF(2^6)
sage: %time A = random_matrix(K,10000,10000)
CPU times: user 1.63 s, sys: 0.06 s, total: 1.70 s
Wall time: 1.70 s
sage: %time B = random_matrix(K,10000,10000)
CPU times: user 1.53 s, sys: 0.04 s, total: 1.58 s
Wall time: 1.58 s
sage: %time (A*B).rank()
CPU times: user 85.03 s, sys: 0.12 s, total: 85.15 s
Wall time: 85.40 s
10000
}}}
With the new spkgs in sage-5.0.beta13:
{{{
sage: K.<z> = GF(2^6)
sage: %time A = random_matrix(K,10000,10000)
CPU times: user 1.77 s, sys: 0.07 s, total: 1.84 s
Wall time: 1.85 s
sage: %time B = random_matrix(K,10000,10000)
CPU times: user 1.76 s, sys: 0.03 s, total: 1.79 s
Wall time: 1.80 s
sage: %time (A*B).rank()
CPU times: user 37.38 s, sys: 0.23 s, total: 37.61 s
Wall time: 37.74 s
10000
}}}
Now, that ''is'' faster for the "real" computation, but roughly 10% slower
for random matrix creation. Is that a random result within the margin of
error?
