data for myApp with the label myLabel. The following command displays performance data for
code called by myApp from libc-2.3.4.so:
% hpcpiprof -label myLabel libc-2.3.4.so
Specifying an Alternate Sort Key
When hpcpiprof and hpcpitopcounts display information for multiple events, the utilities
sort the data table entries according to the event count for the first event in the HPCPI database.
To specify an alternate sort key, use the -st option. The syntax is as follows:
-st event_name
Where event_name is the name of the event.
Example
The following output was created using the same data as the example in “hpcpiprof Output
with Multiple Events” (page 45) , but using the retired instruction count (IA64_INST_RETIRED)
instead of CPU cycles as the sort key. The values for the percentage (%) and cumulative percentage
(cum%) are for the event used as the sort key (IA64_INST_RETIRED).
% hpcpiprof -st IA64_INST_RETIRED

Displaying Raw Values
By default, the HPCPI utilities display values in exponential notation and scaled uniformly so
that the largest value has six significant figures. To display the values using raw numbers, specify
the -raw-numbers option. For example:
% hpcpiprof -raw-numbers
The -raw-numbers option may be useful if some event counts are shown as zero values when
scaled in exponential notation because they are relatively low compared to other event counts.
For example, in the following excerpt from hpcpiprof output, the event counts for
DATA_EAR_EVENTS.CACHE_MISS.GE64
are shown as zero in exponential notation (0e5):
DATA_EAR_
EVENTS
.CACHE_MISS
CPU_CYCLES % cum% .GE64 procedure image

851896e5 89.5% 89.5% 0e5 main myApp
100027e5 10.5% 100.0% 0e5 unknown_rou myApp
Displaying the same data with the option -raw-numbers shows the nonzero values for
DATA_EAR_EVENTS.CACHE_MISS.GE64
event counts:
DATA_EAR_
EVENTS
.CACHE_MISS
