System layout and storage
- 2 Login nodes to transfer data, prepare and submit job files
- 2 NFS servers holding /home, /calc and /scratch directories
- Submit jobs to SLURM
- SLURM sends jobs to compute nodes
System layout and storage
Data can be written to:
- Scratch directory:
/scratch/username(deleted after job) - Calc directory:
/calc/username(persistent) /tmp: local disk on node (deleted after job)/dev/shm: in-memory file system (deleted after job)- Home directory:
/home/username- you can write here (technically) but you should not use it intentionally
- use
/calc/usernameinstead

Configuration of compute nodes:
| partition | CPU | cores | threads | memory | nodename |
|---|---|---|---|---|---|
| E5-2690v4 | 2x Intel Xeon CPU E5-2690 v4 @ 2.60GHz | 28 | 28 | 128 GB | c1-[01-12] |
| E5-2690v4 | 2x Intel Xeon CPU E5-2690 v4 @ 2.60GHz | 28 | 28 | 256 GB | c2-[01-08] |
| Phi | 1x Intel Xeon Phi CPU 7210 @ 1.30GHz | 64 | 256 | 208 GB | c3-[01-08] |
| E5-1650 | 1x Intel Xeon CPU E5-1650 v4 @ 3.60GHz | 6 | 6 | 64 GB | c4-[01-16] |
The current cluster (“smmpmech.unileoben.ac.at”) will be integrated into the new cluster as additional partitions.
