HP XC System 3.x Software - Manual (Page 99)

NOTE: AMD does not provide code-usable names for AMD Opteron processor events. In
addition, the names listed in this section are used for single-core and dual-core AMD Opteron
processors and may differ slightly from the event names used for native quad-core AMD Opteron
processors.
CPU
Displays the following CPU utilization percentages from the /proc/stat file:
•
Idle : CPU utilization for idle cycles
• System : CPU utilization for system processes
• User : CPU utilization for user processes
IPC
Displays retired instructions per cycle.
FPC
Displays floating point operations retired per cycle.
Cycles
Displays the following statistics per unhalted clock cycle:
• Far Transfer Resync : DISPATCH_STALL_FAR_TRANSFER
• Waiting for All quiet : DISPATCH_STALL_QUIET_WAIT
• Segment Load : DISPATCH_STALL_SEG_LOAD
• Serialization : DISPATCH_STALL_SERIALIZATION
• Branch Abort to Retire : DISPATCH_STALL_FROM_BRANCH_ABORT
• LS Full : DISPATCH_STALL_LS
• FPU Full : DISPATCH_STALL_FPU
• Reservation Station Full : DISPATCH_STALL_RESERVE_STATION
• Reorder Buffer Full : RDISPATCH_STALL_EORDER_BUFFER
Execution
Displays the following events per unhalted instruction:
•
Dispatch Stalls : DISPATCH_STALLS
• Decoder Empty : DECODER_EMPTY
• Dispatching : Unhalted Cycles - DISPATCH_STALLS - DECODER_EMPTY
Dcache
Displays the following types of data cache misses per retired instruction:
•
Retired Instructions : Retired instructions (100%)
• L1D Misses : DATA_CACHE_REFILLS_FROM_L2_ALL
• L2D Misses : DATA_CACHE_REFILLS_FROM_LS_FROM.SYSTEM
• Misses : DATA_CACHE_MISSES
• Dcache Fetches : DATA_CACHE_FETCHES
Icache
Displays the following types of instruction cache misses per retired instruction:
