Cluster Details
Atlantis is made up of a small set of shared compute nodes, each with a different mix of CPUs and GPUs. That matters when you are choosing where to run a job, because the resources you ask for should line up with the hardware that can actually satisfy them.
Compute nodes
| Node | Type | CPUs | Cores | GPUs |
|---|---|---|---|---|
monster | compute | Intel Xeon CPU E5-2699v4 | 44 | 4 x AMD Instinct MI210 |
matthew | compute | AMD EPYC 7742 | 64 | 2 x AMD Instinct MI210 2 x NVIDIA P100 |
gauri | compute | Intel Xeon CPU E5-2680v4 | 28 | 6 x NVIDIA GTX 980 Ti |
zixian | compute | Intel Xeon Platinum 8176 | 56 | 8 x NVIDIA RTX 2080 Ti |
khai | compute | Intel Xeon Gold 6138 | 40 | N/A |
Login nodes
Login nodes are the gateway to the cluster. They are where you prepare your work, check on jobs, and do light interactive work. They are not meant for long training runs, large simulations, or benchmarks.
You should reach the cluster through the login node first:
ssh <username>@132.249.248.230
Direct SSH access to a compute node is only available while you have an active Slurm job or allocation on that node. In practice, that means you cannot just pick a compute node and log in whenever you want. You need to earn that access through the scheduler first.
To see where your jobs are and what they are doing, use:
squeue -u $USER
