Re: Dommage...

En fait, il y a pire :

for(ii=0; ii<n ;ii=ii+K)
.for(kk=0; kk<n ;kk=kk+K)
..for(i=ii;i<ii+K;i=i+1)
...for(kkk=kk;kkk<kk+K;kkk+=4){
....tmp6 = A[i][kkk];
....tmp7 = A[i][kkk+1];
....tmp8 = A[i][kkk+2];
....tmp9 = A[i][kkk+3];
....for(j=0;j<n;j=j+128){
.....for(jjj=j;jjj<j+128;jjj+=2){
......C[i][jjj] += tmp6*B[kkk][jjj]+tmp7*B[kkk+1][jjj] + tmp8*B[kkk+2][jjj]+tmp9*B[kkk+3][jjj];
.....C[i][jjj+1] += tmp6*B[kkk][jjj+1]+tmp7*B[kkk+1][jjj+1]
+ tmp8*B[kkk+2][jjj+1]+tmp9*B[kkk+3][jjj+1];
}

Toutes ces boucles embriquées et ces indices dans tous les sens, c'est beau non ?! :)
