ELEC 5200-001/6200-001 Computer Architecture and Design Fall 2007 Homework 6 Solutions Assigned 10/29/07, due 11/5/07 Problem 1: The SPEC ratios are the ratios of run times of a target computer for SPEC benchmark programs with respect to the run times on Sun Ultra 5_10 processor running at 300MHz. Suppose a four-core processor has following SPEC ratios for the SPECINT2000 benchmarks: No. Program Function SPEC ratio 1 gzip Data compression 4200 2 vpr FPGA place and route 2400 3 gcc Gnu C compiler 5100 4 mcf Combinatorial optimization 3000 5 crafty Chess player 3900 6 parser Word processor 3750 7 eon Computer visualization 5250 8 perlbmk Perl application 4500 9 gap Group theory 5250 10 vortex Object-oriented database 7200 11 bzip2 Data compression 3000 12 twolf VLSI place and route 2700 Compute the summary SPECINT2000 performance rating for the dual-core processor. Solution: Taking the geometric mean of 12 SPEC ratios, we get a SPECINT2000 rating of 3991.
