NOTES:

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.
