Installed Runtime Assets (inst/)

This directory should contain only files that are installed with the package and needed at runtime (or package metadata such as citation/legal text).

Runtime scripts

• slavedaemon.R: worker-loop script used by mpi.spawn.Rslaves().
• Rslaves.sh: POSIX launcher used by mpi.spawn.Rslaves().
• MacR64slaves.sh: legacy Intel-mac launcher retained for compatibility.

Metadata

• CITATION: citation metadata returned by citation("npRmpi").
• COPYRIGHTS: copyright notice.

User guidance

• MPI_SETUP.md: current, supported startup patterns for interactive and cluster/batch use.

Historical build/install notes and one-off development artifacts were removed from inst/ to keep installed payload minimal and current.

Canonical Implementation Directive (2026-03-05)

This repository follows a strict canonical execution rule:

1. One canonical implementation per method (outside explicit np.tree branching).
2. Unsupported configurations must fail fast with explicit stop(...) diagnostics.
3. No silent remap/coercion of user-selected options (for example bwmethod, regtype, kernels, cv.iterate, or bounds transforms).
4. No hidden alternate execution paths for the same method semantics.
5. All fit-defining options (for example degree, basis, bernstein.basis, kernels, and bounds) must be propagated and used by the canonical path.
6. np.tree=FALSE is the default; when np.tree=TRUE, behavior must remain semantics-preserving and option-compatible with the canonical path.
7. Remove or reject legacy/debug compatibility branches that add redundant runtime overhead once canonical behavior exists.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
