Metrics Summed for Entire Run 6

-----------------------------------------------

	PLM
Event Name	U..K	TH	Count
-----------------------------------------------
CPU_CYCLES	x___	0	659001879
BACK_END_BUBBLE.ALL	x___	0	99866365
BE_EXE_BUBBLE.GRALL	x___	0	1244270

-----------------------------------------------

PLM: Privilege Level Mask

U/K = user/kernel levels (U: level 3, K: level 0)

The intermediate levels (1, 2) are unused on HP-UX or Linux

x : the metric is measured at the given level (_ : not measured)

TH: event THreshold, determines the event counter behavior, TH == 0 : counter += event_count_in_cycle

TH > 0 : counter += (event_count_in_cycle >= threshold ? 1 : 0)

-----------------------------------------------

%of Cycles lost due to stalls (lower is better):

15.15= 100 * (BACK_END_BUBBLE.ALL / CPU_CYCLES)

%of Cycles stalled due to GR/GR or GR/load dependency (lower is better):

0.19= 100 * (BE_EXE_BUBBLE.GRALL / CPU_CYCLES)
