Add 2-GPU runners: arm64 l4×2 nightly + Windows amd64 special runners - #2090
Merged
Conversation
arm64 l4×2 runners are restricted to nightly-only use per the runner team (ARM64 L4 capacity concerns). Add them as nightly-standard entries in ci-nightly.yml so they run the standard test suite against wheels from the latest successful main CI run. Windows amd64 2-GPU runners (t4×2 TCC, h100×2 MCDM) are added as special runners in the regular PR CI matrix, mirroring the existing Linux amd64 2-GPU special runners. Also update the Windows test job name to show GPU count (x2) for multi-GPU entries, matching the Linux job name format. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

Add 2-GPU test coverage on two new fronts:
arm64 l4×2 (nightly-only)
Per the runner team's request, arm64 2-GPU runners should only be used in nightly CI due to ARM64 L4 capacity concerns. These are added as
nightly-standardentries inci-nightly.yml, which downloads wheels from the latest successful main CI run and executes the standard test suite (pathfinder, bindings, core) — no rebuild needed.Windows amd64 2-GPU (PR CI)
Windows 2-GPU runners have no capacity restrictions, so these are added as special runners in the regular
pull-requestmatrix (mirroring the existing Linux amd64 2-GPU special runners).Other changes
GPU t4 (x2) (TCC)), matching the Linux format.Closes#276, closes#1700.
