Description (last modified by mabshoff)

Hello,

the lround fix we applied to the LinBox? spkg also fixes the Strassen-Winograd optimization test: 

checking best threshold for Strassen-Winograd matrix multiplication...
fgemm 300x300: 0.45 s, 120 Mffops
1Wino 300x300: 0.31 s, 174.194 Mffops

fgemm 300x300: 0.45 s, 120 Mffops
1Wino 300x300: 0.31 s, 174.194 Mffops

fgemm 44x44: 0 s, Inf Mffops
1Wino 44x44: 0 s, Inf Mffops

fgemm 172x172: 0.09 s, 113.077 Mffops
1Wino 172x172: 0.05 s, 203.538 Mffops

fgemm 172x172: 0.09 s, 113.077 Mffops
1Wino 172x172: 0.06 s, 169.615 Mffops
done

This was from the compile test I ran on Neron.

For the updated spkg have a look at
