**CPU Time**is the total amount of User and System time used by all processors.**Wall Time**is the elapsed time measured on a dedicated machine. This includes the time spent processing and any time spent waiting for I/O to complete.**I/O Wait Time**is the total time spent waiting for I/O to complete that is not overlapped by asynchronous I/O. This is included in Wall Time.**Megaflops per Processor**is the theoretical number of floating point operations performed, divided by the CPU time.**Overall Megaflops**is the theoretical number of floating point operations performed, divided by the Wall Time.**Parallel Speedup**is overall increase in performance due to parallel processing.
