mukesh	1c33afec55	ADR-0032 + intra_* opposite directions in IPCQ install ... Add intra_N/S/E/W to install.py _OPPOSITE_DIR table so the intra-cube PE-to-PE namespace is symmetrical with intercube N/S/E/W. ADR-0032 documents the intercube allreduce algorithm (supersedes ADR-0029). Refresh ADR-0024/0025/0029 cross-refs and update test_intercube_sfr_config.py to cover the new intra_* mappings. Drop the obsolete test_ccl_round_robin_recv.py (replaced by intercube tests). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>	2026-04-27 16:43:01 -07:00
ywkang	e1084800ab	docs: add ADRs 0024–0031 for SIP-TP launcher stack ... ADR-0024 (SIP-level TP launcher): rank = SIP abstraction, engine-routed install, mp.spawn parity, epoch barrier, ShardSpec structural coords. ADR-0025 (IPCQ direction addressing): address-based matching for meta arrival and credit return; fixes 2-rank bidirectional ring deadlock. ADR-0026 (DPPolicy intra-device only): remove sip/num_sips fields; ShardSpec uses structural (sip, cube, pe); pe_index property removed. ADR-0027 (Megatron-style TP API): ColumnParallelLinear / RowParallelLinear on top of ADR-0024 launcher. Backlog until 0024/0025/0026 land. ADR-0028 (DTensor support): stub / future work. ADR-0029 (Hierarchical all-reduce): 3-level reduce using all_pes mapper and multi_pe_sip_local validator from ADR-0024. Backlog. ADR-0030 (IPCQ PhysAddr integration): blocked on ADR-0031. ADR-0031 (PhysAddr PE-resource extension): stub; local_offset range-based partition approach; specific ranges TBD.
