- A user accesses a project account containing units of core hour.
- A batch job on the compute system is charged by a number of core hour to measure the compute time.
- Usage of persistent storage including the tape library are currently not accounted.
The core hour to run a batch job are stored in a project account the User Account has access to.
Charge Rates
NHR@ZIB operates system Lise which hold different Compute Partitions containing different types of compute nodes each. The charge rates for the partitions are given in the table.
| one node in partition | charged "core hours" per 1h occupancy time | increased charge rate due to |
|---|---|---|
standard96 standard96:test | 96 | |
large96 large96:test large96:shared | 144 | high memory layout |
| huge96 | 192 | high memory layout |
gpu-a100 | 600 | four NVidia A100 (80 GB) per compute node |
gpu-a100:shared | 150 per GPU | 600 for four NVidia A100 (80 GB) per node |
gpu-a100:shared:mig | 47 per MiG slice | four NVidia A100 (80 GB) splitted each into two 2g.10gb slices (8 per node and currently 24 in total) and one 3g.20gb slice (4 per node and currently 12 in total) |
Job Charge
The charge of core hours for a batch job depends on the number of nodes, the wallclock time used by the job, and the charge rate for the partition used. For a batch job with

A job on 48 cores on partition large96:shared (96 cores per node, 144 core hour) has a reservation for num = 48/96 = 0.5 nodes. Assuming a wallclock time of 3 hours yields a job charge of 216 core hour. |
