I recently measured a Sunfire V20z (dual 2.2 GHz) opteron, I believe it
had 2 scsi disks, 4 GB ram.
Idle 237-249 260-281
Pstream 1 thread 260-277 290-311
Pstream 2 threads 265-280 303-313
Pstream is very much like McCalpin's stream, except it uses pthreads 2
run parallel threads in sync, and it runs over a range of array sizes.
It's the most power intensive application I've found, anything with
heave disk usage tends to decrease the power usage.
It's also great for showing memory system parallelism, say for a dual
p4 vs opteron. I also find it useful for finding misconfigured dual
