Sep 17, 2019 · A core-hour is a measurement of computational time. 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. …Estimated Reading Time: 1 min

The term CPU Hours (processor hours) is a measure of work done; a CPU Hour is the same as a G-hour, as described above. A with G-hours, note that a CPU-hour is is not a direct measure of time. Because some computers are faster than others, CPU Hours are reported in terms of a 1 GFLOP reference machine".

Sep 11, 2020 · The core hour consumption depends on how many cores were used and how long the job took to finish. For instance, 2 core hours are consumed when a simulation runs for 1 hour using a 2 core machine. The formula below is used to calculate the core hour usage from any given job: $$Core\,Hours = Time\ required\ to\ run\ the\ job \times Number\,of\,cores\ used$$ Checking the Core Hours …Estimated Reading Time: 4 mins

Nov 06, 2020 · A core hour refers to the number of processor units (cores) used to run a simulation multiplied by the duration of the job in hours. With 1 core hour you can simulate for 1 hour on a 1 core machine, 30 minutes on a 2 core machine and so on. For additional computing capacity booking please send an email to [email protected].

Aug 31, 2021 · If it takes 500 CPU hours to run a job with 48 cores, how much time would it take to run it in 20 cores? If I use the inverse rule, then I find 1200 hours based on the following: 500 hours * (48/20) cores = 1200 hours.

Mar 19, 2019 · In one series of comparisons, simulating 0.01 seconds of particle flow for 17 million particles in a slowly rotating box took 6.9 hours on 12 CPU cores, while using four GPU cards and just four CPU cores lowered the walltime to only 13.5 minutes. After accounting for ancillary processes, the EDEM solver speedup was shown to reach 60 times!
