Performance Metrics

• time-to-completion (TTC, t_c):
  • defined per session, in seconds
  • time from creation to the teardown of the RP session.
• execution time (t_x):
  • defined per pilot or per session, in seconds
  • duration from start of EXECUTING state for the first executed compute unit to the end of EXECUTING state for the compute unit executed last.
• queuing time (t_q):
  • defined per pilot, in seconds
  • duration which the pilot spent in PENDING_LAUNCH state, ie. in the resource's queuing system.
• pilot utilization:
  • defined per pilot or per session, in percent
  • portion of cores on which a compute unit was in EXECUTING state, integrated over time
• spawning rate:
  • defined per pilot or per session, in units/second
  • rate with which compute units are moved from PENDING_EXECUTION into EXECUTING state
