BinAC2/SLURM Partitions
Partitions
The bwForCluster BinAC 2 provides two partitions (e.g. queues) 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 of GPUs).
| 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 | nodes=1, time=14-00:00:00 |
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
