KVC v2 config from sweep_ts1_migration_v2.sh (reset-on-success + direct-append threshold 8192) layered on top of the RDMA-enabled mooncake stack, against the same outputs/inferact_50sess.jsonl subset that E1 uses. Pair-wise contrast tests H1 (KVC layer marginal contribution on top of 1P3D + kv-aware) and H2/H3 (RDMA reducing reseed slow-path tail).

# E2 — KVC v2 + RDMA, ts=1
|
|
#
|
|
# Tests hypotheses H2/H3 from ONBOARDING_NEXT_AGENT_ZH §3.1: validate
|
|
# that enabling real RDMA pushes TTFT p99 from the reported 1.28s
|
|
# (TCP loopback) down toward ~0.7s (still expected to lose to DP 0.43s
|
|
# because re-prefill segment of reseed slow-path remains).
|
|
#
|
|
# Mechanism = kvcache-centric; policy = kv-aware; topology = 1P3D.
|
|
# All --kvcache-* tuning flags from sweep_ts1_migration_v2.sh
|
|
# (reset-on-success + threshold 8192). RDMA on (mlx5_60).
|
|
#
|
|
# Uses the same outputs/inferact_50sess.jsonl as E1 — see
|
|
# scripts/sample_trace_subset.py — so the two runs are paired.
|
|
#
|
|
# Prerequisites:
|
|
# - source scripts/setup_env.sh
|
|
# - E1 must already have completed (releases GPUs)
|
|
#
|
|
# Usage:
|
|
# bash scripts/sweep_e2_kvc_v2_rdma.sh
