Partitions
The bwForCluster BinAC 2 provides two partitions for job submission. Within a partition job allocations are routed automatically to the most suitable compute node(s) for the requested resources (e.g. amount of nodes and cores, memory, number and type of GPUs).
The gpu partition will only run 8 jobs per user at the same time. A user can only use 4 A100 and 8 A30 GPUs at the same time.
The interactive will only run 1 job per user at the same time.
This partition is reserved is dedicated for testing things and using tools via a graphical user interfae.
The four nodes node1-00[1-4] are exclusively reserved for this partition.
You can run a VNC server in this partition. Please use #SBATCH --gres=display:1 in your jobscript or --gres=display:1 on the command line if you need a display. This ensures that your job starts on a node with "free" displays, because each of the four nodes only provide 20 possible virtual displays.
| Partition | Node Access Policy | Node Types | Default | Limits |
|---|---|---|---|---|
| compute (default) | shared | cpu | ntasks=1, time=00:10:00, mem-per-cpu=1gb | nodes=2, time=14-00:00:00 |
| gpu | shared | gpu | ntasks=1, time=00:10:00, mem-per-cpu=1gb | time=14-00:00:00 MaxJobsPerUser: 8 MaxTRESPerUser: gres/gpu:a100=4, gres/gpu:a30=8, gres/gpu:h200=4 |
| interactive | shared | cpu | ntasks=1, time=00:10:00, mem-per-cpu=1gb | time=10:00:00 MaxJobsPerUser: 1 |
Parallel Jobs
In order to submit parallel jobs to the InfiniBand part of the cluster, i.e., for fast inter-node communication, please select the appropriate nodes via the --constraint=ib option in your job script. For less demanding parallel jobs, you may try the --constraint=eth option, which utilizes 100Gb/s Ethernet instead of the low-latency 100Gb/s InfiniBand.
GPU Jobs
BinAC 2 provides different GPU models for computations. Please select the appropriate GPU type and the amount of GPUs with the --gres=aXX:N option in your job script
| GPU | GPU Memory | # GPUs per Node [N] | Submit Option |
|---|---|---|---|
| Nvidia A30 | 24GB | 2 | --gres=gpu:a30:N
|
| Nvidia A100 | 80GB | 4 | --gres=gpu:a100:N
|
| Nvidia H200 | 141GB | 4 | --gres=gpu:h200:N
