branch Metrics Summed for Entire Run
This section describes the metrics summed over the entire run of your application under HP Caliper.
Metrics for Integrity Servers Itanium 2 Systems
• BR_MISPRED_DETAIL.ALL.CORRECT_PRED
Number of branch predictions that did not require a back-end branch misprediction flush,
independent of predictor. A mismatch between the predicted and actual values of the branch
predicate or target results in a branch misprediction. Return branches must additionally predict
privilege level and previous function state.
• BR_MISPRED_DETAIL.ALL.WRONG_PATH
Number of branch mispredictions that resulted from a mismatch of the predicted and actual
values of the branch predicate, independent of predictor.
• BR_MISPRED_DETAIL.ALL.WRONG_TARGET
Number of branch mispredictions that resulted from a mismatch of the predicted and actual
values of the branch target, independent of predictor.
• Total Predictions
Total number of branch predictions.
• Percent Correct Predictions
Percentage of branch predictions that predicted correctly.
• Percent Wrong Paths
Percentage of branch predictions that mispredicted the branch predicate.
• Percent Wrong Branch Targets
Percentage of branch predictions that mispredicted the branch target.
Metrics for Integrity Servers Dual-Core Itanium 2 and Itanium 9300 Quad-Core Processor Systems
• BE_FLUSH_BUBBLE.ALL
Number of full-pipe bubbles in the main pipe due to either an exception/interruption or a
branch misprediction flush.
• BR_MISPRED_DETAIL.IPREL.CORRECT_PRED
Number of correctly predicted (outcome and target) IP-relative branches retired.
• BR_MISPRED_DETAIL.IPREL.WRONG_PATH
Number of IP-relative branches mispredicted due to wrong branch direction.
• BR_MISPRED_DETAIL.IPREL.WRONG_TARGET
Number of IP-relative branches mispredicted due to wrong target for taken branch.
• BR_MISPRED_DETAIL.NRETIND.CORRECT_PRED
Number of correctly predicted (outcome and target) non-return indirect branches retired.
