Job Time Summary 1

I get the following in the .dat file after running a simulation. Can anyone explain what each of these categories mean. I know the Total CPU Time is the sum of the user time and system time. My ultimate goal is to compare test with different elements numbers and the time it takes to run but exclude everything except the computer time.
USER TIME (SEC) 386.7

SYSTEM TIME (SEC) 31.1

TOTAL CPU TIME (SEC) 417.8

WALLCLOCK TIME (SEC) 702

The only thing that I look at when I do comparisons is the wallclock time - that's the actual number of seconds to solve the problem. It depends on your hardware and whether the solution is solved in-core or out-of-core. Once you exceed the in-core size, the wallclock time will jump quite a bit, but your CPU time should scale nicely.

What's the purpose of performing this comparison? To see that more DOFs take longer to solve? What solver are you using, what OS, how much RAM, what speed of HD I/O, etc...

Thanks
Basically I'm trying to draw a correlation between the number of elements and the time it takes a model to run. Then use this info to justify which one of the proposed methods is best when taking into account accuracy and computational efficiency.
I'm using Abaqus standard and I believe the machine is Windows XP with about 3GB ram.
