measurement | A file that HP Caliper uses to perform a particular measurement, such as scgprof or icache. |
configuration file | Each measurement has a corresponding measurement configuration file. See “HP Caliper |
| |
measurement run | In the HP Caliper GUI, a folder that contains information about the types of data available for a |
folder | single measurement run. It can also contain the collection specification used to collect the data |
| in the folder. |
nop | A |
options file | A text file containing a list of HP Caliper |
| syntax, including a measurement configuration file and program to be measured. |
overview | A measurement that enables collecting fprof, dcache, and cstack data in one single collection |
measurement | run. |
A measurement performed on individual processes, compared with a | |
measurement | performed on all CPUs in the system. |
performance | A set of registers used to configure the performance monitors (PMC) and provide data values |
monitor | from the performance monitors (PMD). In other words, the PMC register maintains control |
configuration | information about what to monitor and the PMD register holds the actual data that results from |
(PMC)/performance | the monitoring. The Integrity servers processor has four |
monitor data | pairs), and the Integrity servers |
(PMD) | 12 |
performance | A unit in the Integrity servers processor family that monitors events on the I/O processor's buses. |
monitoring unit | The PMU is used to calculate bandwidth, data throughput, and efficiency. HP Caliper uses data |
(PMU) | provided by the PMU for its analysis. |
PMU histogram | A report that shows results grouped by function. In HP Caliper, these measurements produce PMU |
report | histogram reports: alat, branch, cgprof, cstack, cycles, dcache, dtlb, fprof, icache, |
| itlb, scgprof, and traps. |
pmu_trace | A measurement, provided by the pmu_trace measurement configuration file, that measures and |
measurement | reports traces of sampled PMU data associated with the application for each kernel thread. |
precise | An |
measurement | path in your program. See “Precise Measurements ” (p. 26). |
predicated off | An instruction that entered the instruction pipeline but had its execution aborted before completion. |
instruction | A predicated off instruction has had its predicate changed to False. A predicated on instruction |
| has a predicate of True. |
predication | A technique used in the Integrity servers processor family whereby possible code branches are |
| executed in parallel before a branch condition is proved. (This is in contrast to the branch |
| prediction technique, where a branch is predicted and executed before the condition is proved.) |
| Instructions are associated with a predicate, which determines whether the instruction will be |
| executed fully or not. With predication, branches and the costs associated with them can be |
| eliminated or lessened. |
prefetch | A request to the main memory system to preload the cache with needed data. |
processor set | On |
| that processor set. Each application is assigned to a processor set and will run only on processors |
| in the assigned processor set. |
project | In the HP Caliper GUI, a set of one or more folders that can contain two types of information: |
| collection specifications and measurement runs. |
register stack | The part of the Integrity servers processor that moves registers between the register stack and the |
engine (RSE) | backing store in memory. |
retired instruction | A successfully (though not necessarily fully) executed instruction. |
rule file | A file used by the HP Caliper Advisor to analyze an application. A rule file contains one or more |
| independent rule functions and is read, compiled, and executed by the Advisor. |
safe instruction | A technique used in the Integrity servers processor family to support precise exceptions. |
