The question is, is the information you want available in the data.

I see starts, completes, kills, and presumed deads.  The question is can
the starts be matched to the completes and kills either from the numbers
before @ or from a combination of the address and NCPU.  You will need to
figure out whether or not you want to count the presumed deads in your
calculations.

Assuming that the starts and stops can be corrilated, it is a simple matter
of finding the pairs and using the datetime module to find the difference
in time between them.
