projark Overview¶

projark is the recommended high-level interface for project archival.

Version¶

projark --version
projark deposit --version
projark retrieve --version

All print the same package-aware message.

Subcommands¶

• deposit: archive local folder content to HPC-DME project collection.
• retrieve: retrieve archived data objects back to local scratch.

Safety Gates¶

Both subcommands run preflight checks:

• parkit checkapisync
• host must be helix.nih.gov
• session must be inside tmux, screen, or an Open OnDemand graphical session
• Disclaimer: Open OnDemand is currently available only on Biowulf compute nodes, not directly on Helix. Since projark is Helix-only today, use tmux/screen on Helix; Open OnDemand support is future-facing until Helix access is available.

Logging and Notification¶

• projark logs include ISO 8601 timestamps.
• On completion/failure, projark sends an email notification to $USER@nih.gov.
• Notification sender is NCICCBR@mail.nih.gov.
