**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.**Megaflops per Processor**is the theoretical number of floating point operations performed, divided by the**CPU Time**.**Overall Megaflops**is the total number of floating point operations performed, divided by the**Wall Time**.**Parallel Speedup**is the ratio of**CPU Time**divided by**Wall Time**.
