I know job runtime is wall clock time, but what is CPU time measuring? If a job were to use 100% of a single core, single CPU's processing resources for the entire runtime of the job would the CPU time always = runtime?
In multi-CPU, multi-core setups if all the CPU's/cores were utilized at 100% would the job CPU time exceed the job runtime? Would the difference between the runtime CPU time be an even multiple of the number of CPU's/cores in this case?
