1. wall time

   Elapsed real time, real time, wall-clock time, wall time, or walltime is the actual time taken from the start of a computer program to the end. In other words, it is the difference between the time at which a task finishes and the time at which the task started. Wall time is thus different from CPU time, which measures only the time during which the processor is actively working on a certain task. The difference between the two can arise from architecture and run-time dependent factors, e.g. programmed delays or waiting for system resources to become available. Consider the example of a mathematical program that reports that it has used "CPU time 0m0.04s, Wall time 6m6.01s". This means that while the program was active for six minutes and one second, during that time the computer's processor spent only 4/100 of a second performing calculations for the program. Conversely, programs running in parallel on more than one processing unit can spend CPU time many times beyond their elapsed time. Since in concurrent computing the definition of elapsed time is non-trivial, the conceptualization of the elapsed time as measured on a separate, independent wall clock is convenient. Another definition of "wall time" is the measurement of time via a separate, independent clock as opposed to the local system's internal time, i.e. with regard to the difference between the two."Real time" in the meaning of "wall time" should not be confused with real-time computing.

1. wall time

   (also wall clock time) 1. ‘Real world’ time (what the clock on the wall shows), as opposed to the system clock's idea of time. 2. The real running time of a program, as opposed to the number of ticks required to execute it (on a timesharing system these always differ, as no one program gets all the ticks, and on multiprocessor systems with good thread support one may get more processor time than real time).
