For most applications, the cpu measurement is the first measurement you should take when you begin using HP Caliper. Run this command:
$ caliper cpu
This will run program, using the default event set of overview and measuring and reporting the following metrics by taking one sample every 8 milliseconds: stall, cpi, dispersal, l1icache, l1dcache, l2cache, tlb, and fp. By default, 125
