CLI Reference

The chia console script (chia/cli/main.py) manages clusters, visualizes flows, and proxies Ray’s CLI (with optional per-cluster targeting).

chia <command> [options]

Cluster management

chia up <config.yaml>

Bring up a Chia/Ray cluster from a YAML config.

Flag

Meaning

-y, --yes

Skip the confirmation prompt.

-v, --verbose

DEBUG logging.

--dry-run

Print the plan and generated scripts without executing.

--add

Only add new nodes to an existing cluster (skip ones already up).

chia down <config.yaml>

Tear down the cluster. Flags: -y/--yes, -v/--verbose.

Visualization

chia viz <source.py>

Render the @ChiaFunction call graph of a flow statically from source.

Flag

Meaning

--func NAME

Orchestrator function (auto-detected if omitted).

--format {svg,png,pdf}

Output format (default svg).

--output-dir DIR

Output directory (default: alongside the source).

chia viz-profile <log...>

Visualize a ChiaProfileCollector JSONL log. See the Profiling guide for how to record one.

Flag

Meaning

--format {svg,png,pdf,html,table}

Output format (default svg); table aggregates exec time to CSV.

--output-dir DIR

Output dir (ignored for table).

--output PATH

(table) CSV path; default stdout.

--funcs ...

(table) function names, or a file of names.

--run N

Run index to visualize (default: last).

--gap-threshold SEC

Gap that segments runs (default 600).

--x-scale F

Horizontal inches per second of wall-clock (default 0.5).

Cluster Status

chia status [...]

Print cluster status. Proxies to ray status.

Flag

Meaning

--chia-cluster {path/to/cluster.yaml}

Specify the Chia cluster YAML file to target.

...

all other args (including --help) go to Ray.

chia list [...]

List all states of a given resource. Proxies to ray list (e.g. chia list nodes).

Flag

Meaning

--chia-cluster {path/to/cluster.yaml}

Specify the Chia cluster YAML file to target.

...

all other args (including --help) go to Ray.

Job Management

chia job <subcommand> [...]

Submit, stop, delete, or list Ray jobs.

Proxies to ray jobsubmit, status, logs, list, delete, etc. all forward, so chia job --help shows Ray’s own job help. Supports --chia-cluster. The one exception is stop, which chia overrides with an augmented implementation; use chia ray job stop for Ray’s unmodified behavior.

Flag

Meaning

--chia-cluster {path/to/cluster.yaml}

Specify the Chia cluster YAML file to target.

stop {job_id}

Stop a job by its ID.

...

all other args (including --help) go to Ray.

chia job stop <job_id>

By default a thin wrapper over ray job stop. With --kill-tracked-pids, it first asks the PID registry actor to kill every tracked subprocess (SIGTERM, then SIGKILL for any that linger past the grace period), then stops the job. The kill returns as soon as the processes have actually exited, so it normally completes in well under the grace period.

Flag

Meaning

--kill-tracked-pids

Kill tracked subprocesses (via the PID registry) before stopping the job. Off by default.

--grace-period SEC

Seconds to wait for each tracked subprocess to exit after SIGTERM before escalating to SIGKILL (only used with --kill-tracked-pids; default 25).

Fallback to Ray (chia ray ...)

chia ray <anything> forwards to ray <anything> verbatim, so every current and future Ray command (ray memory, ray timeline, ray attach …) is reachable — not just the promoted status/list/job. Using an explicit gateway also means chia’s own up/down never shadow ray up/ray down, and chia ray --help shows Ray’s complete command list.

Supports --chia-cluster. Unlike the promoted commands, the fallback applies no overrides — chia ray job stop runs Ray’s stop, not chia’s augmented one:

chia ray memory --chia-cluster=cluster_a.yaml
chia ray timeline
chia ray job stop <job_id>

FireSim

FPGA build/run orchestration:

  • chia firesim-build <config.yaml> --recipe NAME [--instance-type ...]

  • chia firesim-run <config.yaml> [--hw-config ... --workload ... | --suite ...] [...]

  • chia firesim-upload-workload [config.yaml] --marshal-config ... --images-dir ... --suite-name ...

  • chia firesim-cleanup <config.yaml> — terminate orphaned chia EC2 instances.

Run chia <command> --help for the full, current option list.
