Cluster access request

Used to qualify external Customers to access the system for benchmarking and evaluation purposes aiming toward a procurement.

Used to qualify Developers and Ecosystem Partners for validating and benchmarking codes (OSS or commercial) toward incorporating official GG / GH support.

Once you have username and can access the login nodes, follow this example here: Getting Started with HPC-AI AC Clusters to allocate GH nodes.

Connect to the lab

Once you got your username, login to the clusters:

$ ssh <userid>@gw.hpcadvisorycouncil.com

To check available GH nodes using slurm commands.

$ sinfo -p gh
PARTITION AVAIL  TIMELIMIT  NODES  STATE NODELIST
gh         up   infinite      8   idle  gh[001-008]

Please avoid allocating nodes interactively if possible or set the time limit short because we are sharing the resources with multiple users.

$ salloc -N 2 -p gh --time=1:00:00

To submit a batch job

$ sbatch -N 4 -p gh --time=1:00:00 <slurm script>

When you login you are in the $HOME. There is also extra scratch space.

Please run jobs from the scratch partition. It is a Lustre filesystem and it is mounted over InfiniBand.

nfs home -> /global/home/users/$USER/
Lustre -> /global/scratch/users/$USER/
