Processor Information: Information about your processor.
4
Run Information: Information about the run.
5
Sampling Specification: Information about what was being measured.
6
Metrics Summed for Entire Run: Metrics for the entire run are summed:
• CPU_CYCLES is the number of elapsed processor cycles. (CPU_CYCLES is known as
CPU_OP_CYCLES.ALL on the Integrity servers dual-core Itanium 2 and Itanium 9300
quad-core processors.)
• BACK_END_BUBBLE.ALL is full pipe bubbles in the main pipe.
• BE_EXE_BUBBLE.GRALL is full pipe bubbles in the main pipe due to execution unit stalls.
7
Process Summary:
8
Flat Profile Report for matmul: This is a low-level report for the single process that is measured
for this collection run.
For each collection run, one low-level report is produced for each process. A low-level report
can be: data for a single process, data for a group of “matching” processes, or a
module-centric view of all processes.
9
Target Application: Information about your application.
10
Target Execution Time: How long the run took.
11
Sampling Specification: Information about what was being measured.
12
Metrics Summed for Entire Run: Metrics for the entire run are summed. CPU_CYCLES is the
number of elapsed processor cycles. (CPU_CYCLES is known as CPU_OP_CYCLES.ALL on
the Integrity servers dual-core Itanium 2 and Itanium 9300 quad-core processors.)
BACK_END_BUBBLE.ALL is full pipe bubbles in the main pipe. BE_EXE_BUBBLE.GRALL is
full pipe bubbles in the main pipe due to execution unit stalls.

Load Module Summary:
• % Total IP Samples: Percent of the total IP samples attributable to a particular load
module.
• Cumulat % of Total: Running sum of the percent of total IP samples account for by the
particular load module and those listed above it.
• IP Samples: Total number of IP samples attributed to the particular load module.
14
Function Summary:
• % Total IP Samples: Percent of the total IP samples attributable to a particular function.
• Cumulat % of Total: Running sum of the percent of total IP samples account for by the
particular function and those listed above it.
• IP Samples: Total number of IP samples attributed to the particular function.
