*How Core-Hours are Calculated
Core hours are calculated using the formula:
[(End Time - Start Time) * number-of-slots * number-of-cores-per-slot]/3600
Number of slots: this is the number of slots requested in a parallel environment e.g.
#$ -pe mpi-verbose 2 (2 slots)
Number of cores per slot: this varies depending on the parallel environment / queue used
| Queue | Parallel Environment | Cores per Slot |
| parallel.q | mpi / mpi-verbose | 12* |
| gpu.q / gpu-dev.q | gpu / gpu-verbose | 12* |
| serial.q | – | 1 |
| smp.q | smp / smp-verbose | 1 |
* For parallel.q / gpu.q /gpu-dev.q we include all 12 cores on each requested node in the core-hour calculation. This is because any idle cores are not available to other users.
