CSE 141 Ungraded Homework # 2
Recommended "due date" - Jan 23.
- Suppose a program takes 25 seconds on a Pentium PC, and
only 15 seconds on a brand new Itanium machine. Fill in the blanks:
- The Itanium was ____ times faster than the Pentium on this program.
- The Itanium was ____ percent _____ (faster or slower)
than the Pentium.
- The DRAM growth rule is that the capacity of DRAM increases
by a factor of 4 every three years. Figure 1.20 in the text
shows that the performance of workstations has gone from
9 "specmarks" (the unit of performance for the SPEC benchmark)
to 1140 in 10 years. Which is the faster growth rate? Note:
there are (at least) two ways to compute this - you could figure
out how much growth there would be in 30 years (assuming the growth
rates remain the same), or you could determine an average
yearly growth rate for each measure. The best exercise would be
to try it both ways.
