There are only two hard things in Computer Science: cache invalidation
and naming things.— Phil Karlton
My app is reporting CPU time, and people reasonably want to know how much time this is out of, so they can compute % CPU utilized. My question is, what’s the name for the wall clock time times the number of CPUs?
If you add up the total user, system, idle, etc. time for a system, you get the total wall clock time, times the number of CPUs. What’s a good name for that? According to Wikipedia, CPU time is:
CPU time (or CPU usage, process time) is the amount of time for which
a central processing unit (CPU) was used for processing instructions
of a computer program, as opposed to, for example, waiting for
input/output (I/O) operations.
“total time” suggests just wall clock time, and doesn’t connote that over a 10 second span, a four-cpu system would have 40 seconds of “total time.”
