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
