- Add 4-level topology hierarchy setup (zone/block/rack/host) - Add KAI Topology verification utilities - Add topology constraint verification helpers - Include 2 foundational tests: * TI1: Topology infrastructure verification * BP1: Multiple cliques with different constraints - Update dependencies to KAI Scheduler v0.13.0-rc1 - Add Makefile target for selective test execution - Add topology-test skaffold profile Signed-off-by: Ron Kahn <rkahn@nvidia.com>
Add 5 tests for simple topology constraint scenarios: - SL1: PCS-only constraint (inherited by children) - SL2: PCSG-only constraint - SL3: No topology constraints (baseline) - PC1: Host-level constraint (strictest packing) - ZL1: Zone-level constraint These tests verify constraint behavior at different resource levels (PCS, PCSG, PCLQ) and topology domains (zone, rack, host, none). Builds on PR ai-dynamo#348 (infrastructure). Signed-off-by: Ron Kahn <rkahn@nvidia.com>
Add 5 tests for scaling and hierarchical topology patterns: - SP1: Full hierarchy with cascading constraints (PCS→PCSG→PCLQ) - SP2: PCS + PCLQ constraint combination - SP3: PCSG scaling with topology constraints - SP5: PCSG + PCLQ without parent PCS constraint - SP8: Large scaling ratio (6+ replicas) These tests verify: - Hierarchical constraint inheritance and overrides - PCSG-level topology constraint propagation - Large-scale PCSG replica handling - KAI PodGroup SubGroup structure with constraints Builds on PR ai-dynamo#349 (simple level tests).
