Here the results, you'll have to draw your own conclusions. The benchmark is designed to shred the cache and reveal the cost of cache misses. While skimming over McCalpin's pages I noticed that he has a machine balance metric, it might be derived from output of this benchmark. To find out more about the STREAMS benchmark ... http://www.cs.virginia.edu/~mccalpin ftp://ftp.cs.virginia.edu/pub/stream/Code/stream_d.c ftp://ftp.cs.virginia.edu/pub/stream/Code/second_cpu.c Most of the results were compiled using the stock cc (gcc 2.6.3) cc -O stream_d.c second_cpu.c -o stream_d -lm Regards and thanks to all who sent me results, Mike Hancock RESULTS (sorted by Assignment)
