DSH-SCNet

简体中文

DSH-SCNet (dsh-scnet on npm) is a community-maintained DSH bundle for operating Supercomputing Network (SCNet) clusters. It packages the canonical scnet-hpc skill, profile-aware shell utilities, and seven deterministic tools for SSH setup, Slurm job generation, cluster discovery, and compute-node diagnostics.

This is an independent community project. It is compatible with DeepSeek Harness but is not an official DeepSeek product and does not imply endorsement, partnership, or authorization by DeepSeek.

Requirements

• Node.js 22.19 or later
• DeepSeek Harness (dsh)
• Linux or macOS for native shell execution
• Windows through WSL2; native Windows execution is not supported by the bundled Bash scripts
• An SCNet account and cluster credentials for remote operations

Install

dsh plugin --profile web add dsh-scnet

Then verify that the bundle layer is present:

dsh --profile web --dump-config

See Installation for npm, GitHub, and local-checkout workflows.

Included capabilities

| Component | Purpose | | --- | --- | | scnet-hpc skill | Profile-based operating guidance for SSH, Slurm, offline compute nodes, and accelerator validation | | scnet_list_clusters | List packaged cluster profiles | | scnet_show_cluster | Read a selected profile before reporting resource constraints | | scnet_generate_job | Generate profile-aware accelerator or CPU-only Slurm scripts | | scnet_setup_ssh | Configure a local SSH key and host entry with explicit user confirmation | | scnet_probe_cluster | Produce an initial profile from read-only login-node probes | | scnet_refresh_cluster | Refresh time-sensitive profile fields; compute probing is opt-in | | scnet_run_compute_probe | Submit a minimal compute-node capability probe |

Packaged profiles currently cover Zhengzhou, Kunshan, Wuzhen, and Xi'an SCNet environments. Cluster specifications and scheduler policies remain profile-specific and should be verified against the target environment.

The package is a DSH bundle: package.json declares dsh.bundle.patch, and cordis.patch.yml mounts both the tool plugin and the packaged skill directory through @deepseek-ai/dsh-skill-filesystem.

Source synchronization

The skills/scnet-hpc/ directory is generated from the canonical scnet-hpc repository:

./sync.sh --src ../scnet-hpc

Do not maintain the generated directory independently. The sync excludes the canonical installer and local probe cache because neither belongs in the npm runtime package.

Validation

npm install --no-package-lock --ignore-scripts
npm run validate
npm pack --dry-run

See Testing for local package installation and risk-ordered runtime checks.

Security boundaries

• The repository and npm package must not contain private keys, tokens, usernames, private endpoints, or local probe caches.
• SSH configuration, remote probes, and Slurm submission are state-changing operations and require an explicit target and user authorization.
• Generated Slurm files may include local usernames and are ignored by Git.
• Accelerator compatibility claims require evidence from the target compute node.

Branding

The project uses the abbreviated DSH ecosystem identifier in its name. References to “DeepSeek Harness” are descriptive compatibility statements only. No official logo or other DeepSeek brand asset is distributed by this package.
