This page contains a record of your usage of ARCHIE in core hours*. Note, this only includes jobs completed by 3.00am.
*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*|
|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.
