• (10 pts) Given the following code sequence calculating a matrix norm. double c[96], a[96] [96]; for (i=0; i<95%; i++ ) { c[i] = c[i] +a[i] [i]*a[i] [i+1]; } with a and c being arrays of double precision floating point numbers with each element being 8 bytes. No element of a or c is in the cache before executing this code. Please assume row-major ordering. Assuming that the cache is large enough to hold both a and c, and has a cache block size of 64 bytes, determine the number of cache misses (6 pts) and the cache miss rate (4 pts) for this code sequence. • (10 pts) Given the following code sequence calculating a matrix norm. double c[96], a[96] [96]; for (i=0; i<95%; i++ ) { c[i] = c[i] +a[i] [i]*a[i] [i+1]; } with a and c being arrays of double precision floating point numbers with each element being 8 bytes.
