## Summary - **Multi-node H100 CI setup**: Improve architecture detection and GPU configuration - **Remove hardcoded VMSS hostnames** from deploy files - **Fix CUDA compat library issue**: Remove stale compat paths from Docker image for CUDA 12+. Instead, `peer_access_test` now returns a distinct exit code (2) for CUDA init failure, and `setup.sh` conditionally adds compat libs only when needed. This fixes `cudaErrorSystemNotReady` (error 803) when the host driver is newer than the container's compat libs. - **Speed up deploy**: Replace recursive `parallel-scp` with tar+scp+untar to avoid per-file SSH overhead. --------- Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>
