Hi, Dr. McCalpin,

I have done stream benchmark on many PC and Mac systems. Please add the
results to your list. Thanks.

STREAM benchmark result STREAM Benchmark Results

All the data is running at N=1000000 (Default value) in stream_d.c

Basically, you can only use stream to check the double precision throughput over the system bus.  As far as we know, the ideal and the best result of stream is determined by the system bus speed.  For example, all the 66MHz based Intel PII CPUs(233, 266, 300) are running at almost the same result.  Besides the system bus speed, compiler, floating point performance, RAM and even RAM module slot can make the result variant.

Currently, we are using 'stream' as our standard tool to calibrate our memory subsystem.  For further information, please check the overclock example.
