Description (last modified by )
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.

This was fixed a while ago. On

we now have:
