Consider the following CUDA kernel and the corresponding host function that calls it:

$01$ void foo$\_$kernel$($float$*$ a$,$ float$*$ b$,$ unsigned int $N,$

unsigned int N$)$

$02$ unsigned int row $=$ blockIdx.y$*$blockDin$.$y $+$ threadrdx.y:

$03$ unsigned int col $=$ blockIdx.x$+$blockDin.x $+$ threadidx.x $?$

$04$ if $($row col $i$

$06,1$

$I$

vold foo $(float"a_d,$ float" $b_d)i$

unsigned int $\frac{?}{\text{b}\text{a}\text{r}}(M)=150$;

unsigned int $N=300$;

din$3bd(16,32)$;

din$3gd\frac{A-1}{16}+1,\frac{M-1}{32}+1$
