Formulas:
Branch rate = BR_INST_RETIRED_ALL_BRANCHES/INSTR_RETIRED_ANY
Branch misprediction rate = BR_MISP_RETIRED_ALL_BRANCHES/INSTR_RETIRED_ANY
Branch misprediction ratio = BR_MISP_RETIRED_ALL_BRANCHES/BR_INST_RETIRED_ALL_BRANCHES
Instructions per branch = INSTR_RETIRED_ANY/BR_INST_RETIRED_ALL_BRANCHES
-
The rates state how often on average a branch or a mispredicted branch occurred
per instruction retired in total. The branch misprediction ratio sets directly
into relation what ratio of all branch instruction where mispredicted.
Instructions per branch is 1/branch rate.

Group to measure cache transfers between L1 and Memory. Please notice that the
L3 to/from system metrics contain any traffic to the system (memory,
Intel QPI, etc.) but don't seem to handle anything because commonly memory read
bandwidth and L3 to L2 bandwidth is higher as the memory to L3 bandwidth.

evicted from the L1. The group also output total data volume transferred between
L2 and L1. Note that this bandwidth also includes data transfers due to a write
allocate load on a store miss in L1 and traffic caused by misses in the

-
This group measures the locality of your data accesses with regard to the
L2 cache. L2 request rate tells you how data intensive your code is
or how many data accesses you have on average per instruction.
The L2 miss rate gives a measure how often it was necessary to get
cache lines from memory. And finally L2 miss ratio tells you how many of your
memory references required a cache line to be loaded from a higher level.
While the# data cache miss rate might be given by your algorithm you should
try to get data cache miss ratio as low as possible by increasing your cache reuse.

Profiling group to measure L3 cache bandwidth. The bandwidth is computed by the
number of cache line allocated in the L2 and the number of modified cache lines
evicted from the L2. This group also output data volume transferred between the
L3 and measured cores L2 caches. Note that this bandwidth also includes data
transfers due to a write allocate load on a store miss in L2.

The ITLB miss rates gives a measure how often a TLB miss occurred
per instruction. The duration measures the time in cycles how long a walk did take.

This group measures the data traffic on the UPI (socket interconnect). The group
measures all filled data slots (9 slots per 64 Byte data transfer), that's why
the count needs to be divided by 9. These 9 data chunks are not transferred in
a single flit but there is one flit for the header and three flits for the data.
The metrics show higher values as expected because the events count also
different transfers which include data.

Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the
number of cache line allocated in the L1 and the number of modified cache lines
evicted from the L1. The group also output total data volume transferred between
L2 and L1. Note that this bandwidth also includes data transfers due to a write
allocate load on a store miss in L1 and traffic caused by misses in the
L1 instruction cache.

FLx_VAL: This event counts valid cycles of FLx pipeline.
FLx_VAL_PRD_CNT: This event counts the number of 1's in the predicate bits of
request in FLA pipeline, where it is corrected so that it
becomes 16 when all bits are 1.
So each predicate mask has 16 slots, so there are 16 slots per cycle in FLA and
FLB. FLA is partly used by other instructions like SVE stores.

Profiling group to measure L2 cache bandwidth. The bandwidth is computed by the
number of cacheline loaded from the L2 to the L1 data cache and the writebacks from
the L1 data cache to the L2 cache. The group also outputs total data volume transfered between
L2 and L1. Note that this bandwidth also includes data transfers due to a write
allocate load on a store miss in L1 and cachelines transfered in the L1 instruction
cache.

This group measures the locality of your data accesses with regard to the
L2 cache. L2 request rate tells you how data intensive your code is
or how many data accesses you have on average per instruction.
The L2 miss rate gives a measure how often it was necessary to get
cache lines from memory. And finally L2 miss ratio tells you how many of your
memory references required a cache line to be loaded from a higher level.
While the data cache miss rate might be given by your algorithm you should
try to get data cache miss ratio as low as possible by increasing your cache reuse.

Profiling group to measure L2 <-> L3 cache bandwidth. The bandwidth is computed by the
number of cache lines loaded from the L3 to the L2 data cache and the writebacks from
the L2 data cache to the L3 cache. The group also outputs total data volume transfered between
L3 and L2. For streaming-stores, the cache lines are allocated in L2, consequently there
is no traffic between L3 and L2 in this case. But the L2D_CACHE_REFILL event counts these
allocated cache lines, that's why the value of L2D_CACHE_REFILL is reduced
by L2D_CACHE_ALLOCATE.
