EXEC : instructions per nominal CPU cycle
IPC : instructions per CPU cycle
FREQ : relation to nominal CPU frequency='unhalted clock
ticks'/'invariant timer ticks' (includes Intel Turbo Boost)
AFREQ : relation to nominal CPU frequency while in active state (not in
power-saving C state)='unhalted clock ticks'/'invariant timer ticks
while in C0-state' (includes Intel Turbo Boost)
L3MISS: L3 cache misses
L2MISS: L2 cache misses (including other core's L2 cache *hits*)
L3HIT : L3 cache hit ratio (0.00-1.00)
L2HIT : L2 cache hit ratio (0.00-1.00)
L3CLK : ratio of CPU cycles lost due to L3 cache misses (0.00-1.00), in
some cases could be >1.0 due to a higher memory latency
L2CLK : ratio of CPU cycles lost due to missing L2 cache but still
hitting L3 cache (0.00-1.00)
READ : bytes read from memory controller (in GBytes)
WRITE : bytes written to memory controller (in GBytes)
TEMP : Temperature reading in 1 degree Celsius relative to the TjMax
temperature (thermal headroom): 0 corresponds to the max temperature

488 J から 365 J の節電量の低下が見られます．
このマシンはあるアクティブな負荷の下にあり，そのせいで節電はアイドル時より小
さくなってます．
