dcache 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
L1D_READS | The number of data memory read references issued into |
| memory pipeline that are serviced by the L1 data cache |
| (only integer loads), register stack engine (RSE) loads, |
| |
| data cache but does not do a fill) and check loads (ld.c). |
| |
| semaphores, |
| not counted here because the L1 data cache does not handle |
| these. The count includes wrong path operations but |
| excludes predicated off operations. |
L1D_READ_MISSES.ALL | Number of L1 data cache read misses. L1 data cache is |
| write through; therefore, write misses are not counted. The |
| count only includes misses caused by references counted |
| by an L1D_READS event. It will include L1 data cache misses |
| that missed the ALAT, but not those that hit in the ALAT. |
| Semaphores are not handled by the L1 data cache and are |
| not included in this count. |
DATA_REFERENCES | The number of data memory references issued into memory |
| pipeline. Includes check loads, |
| RSE operations, semaphores, and |
| references. The count includes wrong path operations but |
| excludes predicated off operations. This event does not |
| include VHPT memory references. |
L1 Data Cache Miss Percentage | Percentage of L1 data cache reads that are misses. |
Percent of Data References Accessing | Percentage of data references that access the L1 data cache. |

Metrics for Integrity Servers
BE_EXE_BUBBLE.FRALL | Full Pipe Bubbles in Main Pipe due to FR/FR or FR/load |
| dependency stalls. This is the number of cycles lost (stall |
| cycles) due to FR/FR or FR/load dependency. |
BE_EXE_BUBBLE.GRALL | Full Pipe Bubbles in Main Pipe due to GR/GR or GR/load |
| dependency stalls. This is the number of cycles lost (stall |
| cycles) due to GR/GR or GR/load dependency. |
BE_EXE_BUBBLE.GRGR | Full Pipe Bubbles in Main Pipe due to GR/GR dependency |
| stalls. This is the number of cycles lost (stall cycles) due to |
| GR/GR dependency. |
CPU_OP_CYCLES.ALL | Number of elapsed CPU operating cycles. |
DATA_REFERENCES | The number of data memory references issued into memory |
| pipeline. Includes check loads, |
| RSE operations, semaphores, and |
| references. The count includes wrong path operations but |
| excludes predicated off operations. This event does not |
| include VHPT memory references. |
IA64_INST_RETIRED | Number of retired |
| predicated on and predicated off instructions and nops, but |
| excludes |
L1D_READS | The number of data memory read references issued into |
| memory pipeline that are serviced by the L1 data cache |
| (only integer loads), RSE loads, |
