First level of IBM CPI stack. IBM names Stalled Cycles, Waiting to Complete,
|
||
|
|
Thread Blocked, Completion Table Empty, Other and Completion Cycles. For some
|
||
|
|
there are no clearly identifiable events, so this group concentrates on
|
||
|
|
Stalled Cycles (PM_CMPLU_STALL), Thread Blocked (PM_CMPLU_STALL_THRD),
|
||
|
|
Completion Table Empty (PM_GCT_EMPTY_CYC) and Other (PM_CMPLU_STALL_OTHER_CMPL).
