From Chaipat's knowledge graph
mops (Multipurpose Operations CLI) is a lightweight command-line utility in C for MLOps and DevOps work. It brings system diagnostics, a background task queue and cloud operations together in one binary, so the raw numbers a machine reports sit next to the jobs running on it.
Modules
| Command | What it does |
|---|---|
mops sys | System diagnostics: CPU, memory, GPU/TPU use and out-of-memory events; mops mem is a shortcut |
mops task | Task scheduling and management backed by SQLite |
mops worker | A daemon that runs long batch jobs in the background |
mops gcp | Google Cloud helpers: watching for Spot preemption and IAP tunnelling |
mops net | Network observability: listening ports and active connections |
mops dashboard | A live terminal dashboard of resources and the task queue, built on ncurses |
mops doctor | Checks the database, the worker and dependencies |
HPC-style shortcuts
The task queue also answers to the commands of PBS, the job scheduler on HPC and PBS job orchestration clusters: mops qsub submits a task, mops qdel kills one and mops qstat lists them. They are the same commands he used on JAIST's KAGAYAKI cluster during his joint research there.
Engineering
- Command-line parsing uses argtable3, bundled into the source, which gives every subcommand a generated
--help. - The worker daemon was hardened against SQLite locking errors after
fork()and against signal-handling races. Queue polling recovers from schema or database problems instead of stalling silently. - The Makefile tracks header dependencies, builds safely in parallel, and has
lint(cppcheck),format(clang-format) andtesttargets. - Functional tests are written in Python with pytest. A GitHub Actions pipeline runs them headless, faking a terminal so the dashboard doesn't crash in CI.
- It ships as a Debian package (
make deb) with a man page and bash completion.
Building
sudo apt-get install -y build-essential libsqlite3-dev libncurses-dev
make
./mops doctorHistory
Versions 1.1.0 to 1.1.2 came out in April 2026. They added the dashboard, memory metrics, argtable3 parsing, doctor, version and shell completion.
