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, L1-hinted loads (L1
data cache returns data if it hits in L1 data cache
but does not do a fill) and check loads (ld.c).
Non-cacheable reads, virtual hash page table
(VHPT) loads, semaphores, floating-point loads,
and lfetch instructions are 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,
non-uncacheable accesses, RSE operations,
semaphores, and floating-point memory
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 L1 Data Cache
Percentage of data references that access the L1
data cache.
