Jetstream2 GPU

Jetstream2 GPU is a cloud VM service consisting of on-demand GPU-enabled virtual machines in partial- and full-card flavors on NVIDIA A100, L40S, and H100 hardware. It is particularly well suited for interactive GPU work and GPU-accelerated services rather than long batch training runs, and is often used for AI and machine learning, visualization, and GPU-accelerated analysis. It includes whatever software you install, alongside the Jetstream2 software collection.

Submitting Jobs Documentation

Jetstream2 GPU is a cloud virtual-machine resource, not a centrally scheduled Slurm cluster. There is no shared login node and no Slurm queue, partition, sbatch, srun, or squeue workflow. Slurm commands apply only if your project separately deploys and administers its own virtual cluster.

Select an available g3.*, g4.*, or g5.* GPU flavor, create a VM, and connect through Web Shell, Web Desktop, or SSH. GPU availability depends on your project's allocation and quota, and some full-card or multi-GPU flavors require a justified support request. Applications run directly inside the VM, and you install software with the operating system's package manager, Python environments, containers, or the Jetstream2 software collection.

An active GPU instance consumes service units even when no GPU process is running. Shelve an instance when you are not using it; a shelved instance consumes zero compute SUs.

Storage Documentation

Jetstream2 provides cloud storage associated with virtual machine instances rather than a traditional shared HPC filesystem. Instances may use ephemeral or volume-backed root disks. Data on an ephemeral root disk is permanently removed when the instance is deleted; retention of a volume-backed root disk depends on the instance's delete-volume setting.

Persistent storage options include block volumes, OpenStack Manila file shares, and S3-compatible object storage. Volumes can be attached to one instance at a time, Manila shares can be mounted by multiple instances, and object storage can be accessed through S3-compatible tools or HTTP. All Jetstream2 allocations receive 1 TB (1000 GB) of storage quota by default; additional storage can be requested through the Indiana Jetstream2 Storage resource.

File Transfer Documentation

Jetstream2 does not use dedicated data transfer nodes. Files are transferred directly to and from VM instances or through web-based and managed transfer tools.

Common methods include the Exosphere web shell/web desktop file-transfer interface, SCP/SFTP to a VM with a public IP address, and Globus for larger or managed transfers. See the Jetstream2 File Transfer documentation for current guidance.

Login to Jetstream2 GPU Documentation

2FA/MFA required for login

Full instructions are in [Jetstream2 User Interfaces]. Jetstream2 GPU has no shared login node - you reach a machine by creating a virtual machine yourself. Exosphere is the recommended interface and the one these instructions assume; Jetstream2 also supports other OpenStack interfaces if you prefer one. Before your first sign-in:

You need an ACCESS account, and you must be the PI of - or be added to - an active allocation that includes Indiana Jetstream2 GPU.
There is no separate Jetstream2 account. Sign in with your ACCESS credentials, choosing ACCESS CI (XSEDE) as the CILogon identity provider.
ACCESS uses Duo for multi-factor authentication. To enroll or manage your devices, see [Enroll in or manage ACCESS Duo MFA].

Instances created through Exosphere use the exouser account. Once an instance has a public IP address you can connect through Web Shell, Web Desktop, or SSH.
