assume a gpu with the following characteristics

$-$clock rate $2\mathrm{.}3$GHZ

$-$contains $16$ SIMD Processors each containing $16$ double precision floating units

a$)$ what is the peak single precision floating$-$point throughput for this gpu in GFLOP$/$second$?$

b$)$what is the memory bandwisth required to support the peak GFLOP$/$second assuming $40\%$ of operations are addition $($C$=$A$+$B$)$ and $60\%$ of operations are reciprocal $($B$=1/$A$)$
