Qzcli

Configuration

Credentials are read in this priority order: CLI args > --password-stdin > env vars > QZCLI_ENV_FILE (.env) > ~/.qzcli/config.json > interactive input

# Option A: env file (recommended)
mkdir -p ~/.qzcli
cat > ~/.qzcli/.env <<'EOF'
QZCLI_USERNAME="your_username"
QZCLI_PASSWORD="your_password"
EOF

# Option B: environment variables
export QZCLI_USERNAME="your_username"
export QZCLI_PASSWORD="your_password"
export QZCLI_API_URL="https://qz.yourorg.edu.cn"

Config files are stored in ~/.qzcli/: config.json, .cookie, resources.json, jobs.json.

Quick Start

# 1. Login
qzcli login

# 2. Discover and cache workspaces/compute groups (run once, re-run after joining new workspaces)
qzcli res -u

# 3. Check available nodes
qzcli avail

# 4. List running jobs
qzcli ls -c -r

Authentication

# Interactive login
qzcli login

# With credentials
qzcli login -u YOUR_USERNAME -p 'YOUR_PASSWORD'

# Read password from stdin (for scripts)
echo 'YOUR_PASSWORD' | qzcli login -u YOUR_USERNAME --password-stdin

# Check current cookie
qzcli cookie --show

# Clear cookie
qzcli cookie --clear

Note: qzcli avail auto-refreshes the cookie if it expires and credentials are configured.

Resource Discovery

# List cached workspaces
qzcli res --list

# Refresh all workspace resource cache (run this first!)
qzcli res -u

# Refresh a specific workspace
qzcli res -w MY_WORKSPACE -u

# Set a human-readable alias for a workspace
qzcli res -w ws-xxxxxxxx --name "My Workspace"

Check Available Nodes

# All workspaces
qzcli avail

# Including low-priority task nodes (slower but more accurate)
qzcli avail --lp

# Specific workspace
qzcli avail -w MY_WORKSPACE

# Find compute groups with N free nodes
qzcli avail -n 4

# Export IDs for scripting
qzcli avail -n 4 -e

# Show idle node names
qzcli avail -w MY_WORKSPACE -v

Job Submission

Interactive (recommended for first-time use)

# Full interactive selection: workspace → project → compute group → spec
qzcli create -i

# Interactive for a specific workspace only
qzcli create -i -w "My Workspace"

The TUI shows GPU type, availability, and spec status at each level. Press Enter/→ to go deeper, ← to go back.

Non-interactive

# Using names (resolved from qzcli res cache)
qzcli create \
  --name "my-training-job" \
  --command "bash /path/to/train.sh" \
  --workspace "My Workspace" \
  --compute-group "My Compute Group" \
  --image YOUR_REGISTRY/team/image:tag \
  --instances 4 \
  --priority 10

# Using IDs directly
qzcli create \
  --name "my-job" \
  --command "bash /path/to/train.sh" \
  --workspace ws-YOUR_WORKSPACE_ID \
  --compute-group lcg-YOUR_LCG_ID \
  --spec YOUR_SPEC_ID \
  --image YOUR_REGISTRY/team/image:tag \
  --instances 4

Key parameters:

# Preview before submitting
qzcli create --name test --command "echo hi" --workspace "My Workspace" \
  --image YOUR_IMAGE --dry-run

Env-var passthrough (for existing submission scripts)

# Pass vars directly — do NOT use "export VAR; bash script.sh"
WORKSPACE_ID="ws-YOUR_WORKSPACE_ID" \
LCG_ID="lcg-YOUR_LCG_ID" \
SPEC_ID="YOUR_SPEC_ID" \
CHECKPOINT_DIR="/path/to/checkpoint" \
bash YOUR_SUBMIT_SCRIPT.sh

HPC / CPU jobs (Slurm)

qzcli hpc \
  --name "my-cpu-job" \
  --workspace ws-YOUR_WORKSPACE_ID \
  --compute-group lcg-YOUR_LCG_ID \
  --predef-quota-id YOUR_QUOTA_ID \
  --cpu 55 --mem-gi 300 --instances 30 \
  --image YOUR_REGISTRY/team/cpu-image:tag \
  --entrypoint "cd /path/to/dir && bash run.sh"

Batch Submission

# Submit from config file
qzcli batch batch_config.json --delay 3

# Preview all jobs
qzcli batch batch_config.json --dry-run

# Continue on error
qzcli batch batch_config.json --continue-on-error

Config format (batch_config.json):

{
  "defaults": {
    "workspace": "ws-YOUR_WORKSPACE_ID",
    "compute_group": "lcg-YOUR_LCG_ID",
    "spec": "YOUR_SPEC_ID",
    "image": "YOUR_REGISTRY/team/image:tag",
    "instances": 4,
    "priority": 10
  },
  "matrix": {
    "checkpoint": ["/path/to/ckpt1", "/path/to/ckpt2"],
    "step": [50000, 100000]
  },
  "name_template": "eval-{checkpoint_basename}-step{step}",
  "command_template": "bash eval.sh --checkpoint {checkpoint} --step {step}"
}

Matrix keys are Cartesian-producted (2×2 = 4 jobs above). Use {key_basename} for path basenames.

Shell loop (alternative)

for step in 040000 050000 060000; do
  qzcli create \
    --name "eval-step${step}" \
    --command "bash eval.sh --step $step" \
    --workspace "My Workspace" \
    --compute-group "My Compute Group" \
    --instances 4
  sleep 3
done

Job Management

# List jobs
qzcli ls -c -w MY_WORKSPACE          # specific workspace
qzcli ls -c --all-ws                 # all workspaces
qzcli ls -c -w MY_WORKSPACE -r       # running only
qzcli ls -c -w MY_WORKSPACE -n 50    # show 50

# Stop a job
qzcli stop JOB_ID

# Job status / details
qzcli status JOB_ID

# Watch all running jobs (refresh every 10s)
qzcli watch -i 10

# Workspace view with GPU utilization
qzcli ws
qzcli ws -a           # all projects
qzcli ws -p "My Project"
