Paxos

  • Algorithm executes multiple rounds.
  • An acceptor votes to accept atmost one value in a single round.
  • Goal: Achieve consistency by ensuring that different values are not chosen in different rounds.
  • Note that rounds can run concurrently, may be skipped altogether.

HW_PRE_REQ.DL1_MISS	Hardware Prefetch requests that miss the L1D cache. A request is being counted each time it access the cache & miss it including if a block is applicable or if hit the Fill Buffer for example.(This accounts for both L1 streamer and IP-based (IPP) HW prefetchers. )														
L1D.REPLACEMENT	Counts the number of lines brought into the L1 data cache.														
L1D.ALLOCATED_IN_M	Counts the number of allocations of modified L1D cache lines.														
L1D.EVICTION	Counts the number of modified lines evicted from the L1 data cache due to replacement.														
L1D.ALL_M_REPLACEMENT	Cache lines in M state evicted out of L1D due to Snoop HitM or dirty line replacement
