Context
PR #85 landed the Wave 1 chapel-ci scaffolding (six strict gates,
detachable-harness ADR, four silent-loss fixes in Imaging.chpl,
`--resume` hard-fail in static mode). Wave 1 chapel-e2e exercises
`mass-panic --numLocales=1` against a synthetic 2-repo corpus.
True multi-locale execution (`-nl 2` and higher) requires Chapel
built with `CHPL_COMM=gasnet` (or `ofi` / `ucx`). The stock
`chapel-2.8.0-1.ubuntu22.amd64.deb` ships with `CHPL_COMM=none`
and rejects `-nl >1` with:
```
error: Only 1 locale may be used for CHPL_COMM layer 'none'
```
Wave 2 scope
-
CI install path for multilocale Chapel — either:
- A `chapel-multilocale-2.8.0` .deb if upstream publishes one, or
- A build step that rebuilds Chapel from source with
`CHPL_COMM=gasnet` + `CHPL_LAUNCHER=…` flags
(slow — caches required to keep CI under a few minutes), or
- Self-hosted runners with multilocale Chapel preinstalled.
-
`chapel-multilocale` CI job — add to `.github/workflows/chapel-ci.yml`,
bumping the gate count from 6 to 7. Exercises `-nl 2` against the
same synthetic 2-repo corpus as `chapel-e2e` so the cross-locale
code path runs even on a single GH runner (locales oversubscribed).
Add to the Base ruleset's `required_status_checks` once green
(ruleset id 14968583).
-
Non-trivial corpus benchmark — once a multilocale runner is
available, exercise a ~50-repo cluster scan to verify the queue
scheduler's resumability claims and produce numbers for the
"~5–15% slower" assertion in `chapel/README.md` that's currently
labelled "estimate pending Wave 2 benchmark".
