What are Core-Hours? How are they estimated? – OnScale

    https://support.onscale.com/hc/en-us/articles/360013402431-What-are-Core-Hours-How-are-they-estimated-
    In OnScale, if you run one CPU for one hour, that's one core-hour. If you run 1000 CPUs for 1 hour, then that's 1000 core-hours. Estimation. Users will be spending core hours to run their simulations and design sweeps so we feel it is necessary to …

How do I convert CPU hours to MIPS for mainframe …

    https://searchdatacenter.techtarget.com/answer/Converting-CPU-hours-to-MIPS-Mainframe-capacity-planning-process
    This equation demonstrates how to calculate MIPS for mainframe workloads. CPU seconds to MIPS conversion example. A mainframe job has used 100 CPU seconds during one minute -- it is a multitask job. The system is an IBM 2064 Model 1C5 (1085 MIPS, EUM = 217 MIPS). The average consumption speed of this job is 100 x 217/60 = 362 MIPS.

    There are 60 seconds in a minute, 60 minutes in an hour, and 24 hours in a day. That's 86400 seconds in a day. Multiply that by 1000, and you've got the number of milliseconds in a day. You should now be able to work out the number of days from the beginning of time (January 1, 1970, 00:00:00 GMT).
