Panel Discussion
================
"Are longer benchmarks more representative?"

How long should benchmarks be? Seconds? Minutes? Hours? Days? Many
SPEC benchmarks run for half an hour or so. All events of interest
in a CPU benchmark including cache misses and page faults take much
shorter than that.  How long do you need to characterize a system to
perform an effective characterization?
