PMI crate

pmi is a thin Rust wrapper that lets Lamellar (and other crates) consume PMI-1, PMI-2, or PMIx depending on the features you enable.

Features

  • with-pmi1, with-pmi2, with-pmix enable the corresponding backend. Each pulls in the matching *-sys crate and the associated native libraries.
  • vendored attempts to build the bundled implementations instead of requiring a system provider; it combines with the with-* flags (with-pmi1-vendored, etc.) to force a vendor build for the requested protocol layers.

Usage

Add pmi as a dependency and choose the backend that matches the process manager on your cluster. Use the vendored features when you do not have a system PMI/PMIx stack available yet still need to run Lamellar examples with job-level coordination.

STATUS

pmi-rs has been developed as part of the Lamellar project and is still under development, thus not all intended features are yet implemented.
