Suppose two 100 × 100 matrices are to be multiplied using 8 threads. How many

dot products, i.e., operations performed by the innermost for loop, must each

thread compute if different approaches to parallelizing the two outermost for

loops of matrix multiplication illustrated in Fig. 3.6 are used?
